Referring to Fig. 2, each launcher 300 is configured for speed-launching at least one UAV 400 in an automated manner in response to receiving a control command signal to do so, and thus each launcher 300 is configured for operating unattended, hi the embodiment illustrated in Fig. 2, the launcher 300 is configured for speed-launching one or a plurality of UAV's and comprises a plurality of launch housings 310, each launch housing 310 housing a UAV 400, which in operation of the respective launch housing 400 is in a ready for launch mode (RFL mode). In alternative variations of this embodiment, at least one launcher is configured for speed-launching one UAV and comprises a respective launch housing. The launch housing 310 further comprises a suitable launching system (not shown) configured for imparting a forward momentum to the respective UAV 400 sufficient to enable the UAV to become airborne and subsequently be capable of maintaining flight under its own power after exiting the respective launch housing 310. For example, the launching system may be configured for launching the respective UAV via any suitable pneumatic, hydraulic, pyrotechnic, elastic, mechanical or other arrangement.
In alternative variations of this embodiment, the launch housing 310 does not comprise any specific mechanism or arrangement to eject and push out the respective UAV 400 therefrom for launching the same. Rather, the UAV 400 is itself configured for exiting the launch housing 310 under its own power - for example the UAV may have VTOL, STOL or V/STOL capabilities, and/or may comprise auxiliary power packs (e.g. rocket assisted take-off systems).
The launcher 300 further comprises a suitable communication system 350, comprising at least a receiver for receiving command signals transmitted by the control center 200.

Such data may include human intelligence, for example observers 490 in the field may spot a suspected target T and radio or otherwise advise the control center 200 of the fact and location of the suspected target T.
Where the system 100 is used for guarding a perimeter against infiltration, wherein the target is an infiltrator, additionally or alternatively, breaches in the perimeter (e.g., a fence, wall, etc.) may be sensed optically and/or thermally and/or by sound and/or by touch/movement and/or electronically, and data indicative of the breach is suitably transmitted to the control center 200. Additionally or alternatively, human intelligence data may include data of a possible infiltration at a particular time and/or place, and this data is suitably transmitted to the control center 200.
Additionally or alternatively, the control center 200 may comprise a receiver for receiving satellite intelligence data from a satellite network 492, for example satellite image data (visible spectrum, infra red, etc) of a particular target zone at a particular reference time, and this image data may be analyzed to provide such intelligence data to the control center 200. Additionally or alternatively, the control center 200 comprises or is operatively connected to a suitable sensing module, for example any suitable SIGI T module for intercepting signals, optionally including at least one of an ELINT module and a COMINT module.
Additionally or alternatively, the control center 200 comprises a suitable detection system 270 (which may comprise, for example, a suitable radar system and/or a suitable ground based electro optic system) operatively connected thereto for detecting a target T within a particular radius of operation, around the control center 200 and/or around one or more additional zones, wherein a number of linked radar systems and/or ground based electro-optic systems may be provided for radar coverage thereof.

The UAV 400 is configured for being automatically launched from its respective housing 310 when in the aforesaid RFL mode, in which the respective UAV 400 is fuelled and/or has sufficient electrical power to enable operation of the propulsion system and for powering the additional on-board systems, for example the imaging system 410 a nd communications module 420. At least in this embodiment, each operative said launcher comprises at least one said UAV in RFL mode, and may have additional said UAV's in RFL mode, and/or is configured for placing more said UAV's in RFL mode in an automated manner.
Once launched, the UAV may be steered to the desired location in any number of ways. For example, the UAV may receive a particular flight plan to the target zone while still in the launcher housing prior to launch via a suitable communication, or may up-load the flight plan after launch via suitable data-link. Additionally or alternatively, the UAV may be pre-programmed with a plurality of flight plans, for example one each to particular predetermined target zones, and the desired flight plan is brought on-line in the UAV. Alternatively, the UAV is steered manually to the target zone via a UAV operator 205.
In variations of this embodiment where the launched UAV 400 comprised a payload, for example the imaging system or other payload, the payload may be operated by means of a payload operator 206, who optionally may also be the UAV operator 205.
In this embodiment, the payload operator 206 and the UAV operator 205 are comprised in the control center 200, and are located in the same location. In alternative variations of the embodiment, the payload operator 206, and/or the UAV operator 205, may be independent of the control center 200 and may be located at different geographical locations.
In this embodiment, the UAV 400 further comprises a suitable GPS or the like, and the communication module 420 is configured for transmitting the geographical location of the UAV 400 to the control center 200. Furthermore, the communication module 420 may further transmit the direction of the LOS of imaging system 410 with respect to datum coordinate system UCS of the UAV, the UAV's direction and altitude, and the attitude of coordinate system UCS with respect to an Earth-based coordinate system ECS such as used by the GPS system, and may also further transmit data regarding the magnification of image and other optical parameters. With this data it is possible to then calculate the position and thus the geographical location (with respect to the aforesaid Earth-based coordinate system) of whatever object is in the field of view FOV of the imaging system 410.
Furthermore, the communication module 420 is also configured for providing identification data for the respective UAV 400, for example an IFF or IP code, so that data received from each UAV by the control center 200 can be associated with its respective UAV 400.
In one application of the first embodiment, and referring to Fig. 1, the system 100 is configured for facilitating guarding of a particular perimeter, for example defending the perimeter against infiltration, and the plurality of launchers 300 (individually designated as 300a, 300b, 300c, etc.) are deployed along the perimeter. For example such a perimeter may be a political border 900 between the host nation 910 on which the launchers are deployed and a neighboring nation or other geographical/geopolitical entity 930 which may be hostile or harbor hostile or undesirable elements with respect to the host nation 910. Each launcher 300 has an associated radius of operation R, which can be understood to refer to a characteristic range of the respective UAV 400, attained after a predetermined elapsed time t from launch from the respective launcher 300. The elapsed time t may thus be regarded as a desired response time for the UAV to reach a particular location. In this embodiment, the various launchers 300 are spaced from one another and from the border such that each radius of operation R (individually designated as Ra, Rb, Rc, etc. respectively corresponding to the respective launchers 300a, 300b, 300c, etc.) overlap with the border 900, and also with respect to one another at least close to the border 900, as illustrated in Fig. 5.
The control center 200 is also located in the host nation 910 (although in variations of this embodiment it may be elsewhere, for example airborne or at sea in neutral or international areas), but may be further distanced from the border 900, for example for site security considerations, particularly if the border zone in the vicinity of the border 900 is hostile.
The border 900 may comprise a fence or wall 920, comprising sensors 925 including proximity sensors and/or breaching sensors, respectively configured for sensing proximity of a foreign object (for example a body or vehicle) to the wall and for sensing breaches in the wall, and a communication module 930 for transmitting to the control center 200 sensor data indicative of such proximity or breach when such an event happens.
In this embodiment, all the launchers 300 are substantially similar to one another, at least in terms of the type of launching systems provided, and the type of UAV launched by each housing 310, and may also be similar to one another in having the same number of launch housings 310 per launcher, though in alternative variations of this embodiment, each launcher may have a number of launch housings that may the same or different with respect to the other launchers 300. In yet other variations of this embodiment, each launcher may be different from the other launchers, in terms of type of launching systems provided, and/or in terms of the type of UAV launched by each housing 310 of the launcher, and/or in terms of the number of launch housings 310 per launcher 300, and so on. Accordingly, the radius of operation R associated with each launcher 300 may be different from one another between the different launchers 300.
In this application of the first embodiment, a number of launchers 300 are in communication with the control center 200 via wireless transmitters 292, while other launchers 300 are in communication with the control center 200 via cables 295. In one method of operation of the system 100, designated with reference numeral 800 and referring also to Fig. 8, in step 810 the control center 200 receives intelligence data of a possible incursion or infiltration of the border 900 at a particular target zone at location A, for example via sensors 925. Alternatively, such data may originate from one or a combination of the following sources: human intelligence, electronic intelligence, satellite surveillance, etc. The CC Module 210 makes a command decision at 805 whether or not to investigate further, and in the affirmative, a command signal CS is sent out in step 820 to one or more launchers 300 for one or more UAV's to be launched. In the simplest implementation of step 820, the command signal CS is for launching a single UAV from the launcher closest to the location A, or if the launchers 300 have different UAV capabilities to one another, the launcher having the shortest response time T to the location A. The particular UAV 400 is automatically launched by the respective launcher 300 responsive to receiving the command signal CS and the UAV is automatically flown (by computer control) or manually flown (by UAV operator 205) to location A, with the respective imaging system 410 aboard the UAV 400 scanning the target area around the location A for signs of a candidate target such as an intruder.
When a candidate target has been acquired, e.g. detected digitally or in any other suitable manner and homed onto, the next step 830 is to identify the target, and this is followed by decision node 840 - whether this identified target warrants further tracking or not. For example if the target is a human infiltration agent, for example an intruder such as a potential terrorist, illegal alien, smuggler, thief, foreign troops, etc., for example, tracking of the target is continued, while if it turns out that the target is a border guard, a tourist, an animal etc., for example, or it may be decided that the target does not warrant further tracking. On the other hand, the target may be a non-human infiltration target, for example a dangerous animal (e.g., an animal suspected of carrying rabies or an infectious disease), or the target may be a non-human agent such as for example a non-authorized UAV or unmanned land or sea vehicle. In any case, if further tracking is required, then in step 850 the UAV maintains aerial surveillance of the target, in general by maintaining the target within the field of view FOV of the imaging system 410.
Further tracking can be manually performed, for example by the UAV operator 205 controlling the UAV in cooperation with the payload (imaging system) operator 206 (which in at least some embodiment may be the same operator), typically at the control center 200 though the operator 206 may be stationed at a different location and communicates with the UAV to control operation thereof via suitable communication means.
Alternatively, the tracking may be automated, for example by means of a suitable computerized system and/or an electro-optical auto tracking system.
The fact, details and other data of the target, including its location in real time, may be relayed by the control center to any desired party, for example ground forces such as border patrol, police etc. that are responsible for confronting and dealing with the target.
In step 860, tracking may be terminated, for example when suitable ground forces such as border patrol, police etc. arrive at the location of the target, which has been continuously tracked and relayed to the ground forces via control center 200 by the UAV, and the ground forces may then deal with the target, for example by neutralizing or apprehending any potential threat. The ground forces may include one or more of personnel and vehicles (manned or unmanned), and/or air vehicles and/or sea vehicles as appropriate.
In step 870 the UAV is recovered. For example the UAV may be flown to a recovery site, where it is landed and refurbished, to be subsequently re-used in the original or a different launcher 300 when needed.
In a further optional step 855 prior to step 860, another UAV 400 may be automatically launched from the same or a different launcher 300 in response to receiving a suitable command signal to take over or to assist tracking of the target. This may occur, for example, when the original UAV is damaged, or when the original UAV lacks sufficient fuel or electrical power to maintain tracking operation. In such cases, the operational status of the original UAV is monitored, and the next UAV is launched such that its response time T is less than the estimated time to failure of the original UAV. Thus, location data of the original UAV is used to guide the second UAV to the target and take over tracking, such that tracking and surveillance of the target is effectively continuous and uninterrupted.
In a variation of this method of operation, a number of UAV's may be launched sequentially or substantially concurrently in step 820. This may provide multiple redundancy in tracking - for example if one UAV suddenly fails the other UAV's can still provide tracking data. Alternatively, it may turn out that what was initially considered to be a single target is in fact a group of targets that may potentially scatter in different directions, and thus the multiple UAV's may provide tracking of each separate target if there are sufficient targets launched (of course, once the target is identified in step 830 as comprising multiple targets, additional UAV's may be automatically launched and homed in to their location via the data provided by the first UAV. Alternatively, and depending on the terrain on which the target is located, it may be possible for the target to enter a structure having multiple exits, and the strategic solution for ensuring continuation of surveillance is to cover all the exits by providing a UAV to survey each such exit.
In another variation of step 820, designated as step 820' in Fig. 8(a), three UAV's (designated with reference numerals 400a, 400b, 400c) are launched in response to the command signal CS, and is particularly useful where the exact location of the suspected target T is not known with certainty and/or where it is suspected or known that the suspected target T may move quickly from the last known location within the time taken for the nearest UAV to arrive at this location. In alternative variations of this embodiment, two UAV's or alternatively more than three UAV's may be launched in step 420' instead of three. In such cases, a probability zone PZ may be defined around the last known location of the suspected target T, or centered around the area where the suspected target is general located. Thus, perimeter P is displaced by a dimension S from the center C of the probability zone PZ such that the perimeter P defines a threshold beyond which it is considered unlikely (within a predefined probability which may differ from case to case) that the suspected target will have traveled, even if traveling at a known, predicted or estimated maximum speed, irrespective of direction, in the time period between detection of the target and the arrival of at least one of the UAV's. While the shape of the probability zone PZ is illustrated as circular, it is not necessarily so, and the probability zone may take on any suitable shape, which may generally depend on the nature of the suspected target, its means of mobility, and the nature of the terrain.
In step 820' the three UAV's are launched, each one to a different part of the probability zone PZ. For example: UAV 400a and UAV 400b are each directed to generally opposed extremities, target points La and Lb respectively, of the probability zone PZ at the perimeter P, while the third UAV 400c is directed to a target point Lc at or near the center C of the zone. The three UAV's may be launched from the same launcher 300 or from different launchers 300, optimally according to availability of UAV's in each launcher and according to satisfying the criteria of minimizing the response time of each UAV to its designated target point.
For example, La and Lb may lie along the generally direction that the target was observed to be traveling when detected. Alternatively, La and/or Lb and/or Lc may be locations in the probability zone PZ having relative high probability of finding the suspected target there. If the suspected target is located by one of the UAV's, steps 830 to 870 may be implemented with respect to this UAV, and the other two UAV's may be recovered as per step 870, or at least one of these two UAV's may be used to provide multiple redundancy in tracking, as disclosed above, mutatis mutandis.
On the other hand, if by the time the three UAV's reach their target points La, Lb, Lc the suspected target is not located by any of the UAV's, step 825' is then implemented, in which the probability zone PZ is split into three search zones Za, Zb, Zc, one zone for each UAV, and which each UAV 400a, 400b, 400c implements a search-and-locate mission M in its respective zone Za, Zb, Zc (Fig. 7). For example, each mission M may follow a zigzag path that eventually covers the full respective zone such that the zone comes under observation by the respective imaging system 410 of the respective UAV.
It is to be noted that the probability zone PZ is not necessarily of a static and fixed form. For example, if further intelligence data regarding the suspect target is received while the UAV's are on their way to the probability zone PZ or while they are carrying out their missions M, the shape and extent of each respective zone Za, Zb, Zc may be changed, as well as the number of zones searched and/or the form of the mission M changed. Additionally or alternatively, if the suspected target is not detected within a particular time, it may be necessary to expand and/or displace the probability zone PZ to account for the possibility that the suspected target may have traveled further and out of the probability zone PZ. One possible way to address the expanded probability zone PZ is by extending each mission M accordingly. Another way is to define a new search zone Zx between the original perimeter P of the probability zone PZ and the expanded perimeter P' of the expanded probability zone PZ, and to launch one or more additional UAV's to search this zone Zx. Of course, this process may be repeated as often as necessary, each time expanding the probability zone PZ as required. In some cases, it is possible to concurrently have a number of groups of UAV's, each group operating with respect to a respective different probability zone. In such cases, it is also possible to transfer UAV's from one group to another according to specific needs or requirements. For example, it may be that a UAV of one group happens to be closer to a target zone of one particular probability zone than the original UAV that was dispatched to that zone. In another example, rather than launching a new UAV to a particular target zone it may be possible to divert a UAV, that was originally deployed for a different probability zone, to the aforesaid target zone.
In these or other applications of the system 100, the respective UAV's 400 may at least in some cases be tactical, mini- or micro- UAV's and/or operated from high altitudes such as to minimize the probability of being detected in flight by the suspected target, and thus reduces the probability of the suspected target from taking evasive action to avoid detection or being tracked. Furthermore, such small-sized UAV's may be maneuvered through confined spaces, for example wooded areas and urban areas in a fast, slow or hovering flight, and in a controllable manner, at least in some cases with greater effectiveness, more safety and lower probability of detection than would be the case with manned air vehicles.
Additionally or alternatively, at least in some cases larger UAV's may be used where endurance may be required - for example where it is expected that the ground forces cannot arrive and take over for long periods.
In another application of the system 100, one or a plurality of launchers 300 may be provided atop masts or rooftops in an urban zone. For example, a launcher 300 may be installed on a rooftop of a building housing a bank and/or of a nearby building or at any other strategic locations. In case of a robbery or attempted robbery, the launcher 300 automatically launches one or more UAV's which can then follow the getaway vehicle used by the criminals until a helicopter can take over surveillance and/or until the vehicle is apprehended. The command signal for activating the system 100 and launching the UAVs may be generated and transmitted, for example automatically on activation of the bank alarm system, or via a coded signal sent directly by law- enforcement agents in the area.
In another application of the system 100, one or a plurality of launchers 300 may be additionally or alternatively provided atop vehicles, for example law enforcement vehicles or military vehicles, which may be moving such as on patrol. When required, a UAV from such a vehicle is launched responsive to receiving the command signal CS from the control center 200.
In another application of the system 100, one or a plurality of launchers 300 may optionally be provided atop vehicles, for example emergency and rescue forces vehicles (e.g., fire fighters, environmental agencies etc), which may be deployed to answer an emergency situation. When required, a UAV 400 from such a vehicle (and/or from static locations such as illustrated in Fig. 1, for example) may be launched responsive to receiving the command signal CS from the control center 200. The launcher 300 may stay on the vehicle or may be removed and re-positioned for later usage. The UAV may include as payload, in addition to or instead of the image sensor, a contamination sensor configured for detecting and/or identifying toxic or otherwise dangerous chemical, biological, radiological or nuclear agents, and the UAV is operated to fly into a target zone that is suspected to include such agents. Such a target zone may be associated with a perimeter defining the site of an attack, or may be a building or complex that stores or processes such agents, and the target zone may include a body of such agents, for example smoke or a cloud of particulate matter, or precipitation or a mist, for example. The UAV then uses the contamination sensor to collect and identify any possible contaminants at the target zone, and to enable associated risks to be evaluated. Furthermore, the UAV may stay airborne and track the movement of the body of agents, until they are sufficiently dispersed as to be rendered harmless, or until other resources may be brought into play to deal with the contamination. Optionally, a plurality of UAV's may be launched to monitor and track the body of agents if this expands or moves in multiple directions at the same time.
Thus, in this application of system 100, the suspected contamination agents operate as infiltration agents at the target zone.
