The optical sensor unit 30 is configured to capture the image of the target and relay it to the digital control unit 200 for processing and analysis. This simulated launching training system 1000 also comprises a visor mounted display module 320. Activities are simulated and video input is provided through the visor mounted display module 330. Also, a provision is made to connect the visor mounted display module 320 and performance monitoring and report generator module 310 coupled with the digital control unit 200. This simulated launching training system also comprises an associated preparation bench or work stand to load, compress and lock the spring along with a simulated projectile. The performance monitoring module 310 is configured to analyse the simulated activities and the video input provided through visor mounted display module 330.

In another embodiment, this motion simulator 100 is also connected to the Portable Indoor Training System 300 for combining the features of indoor simulation and outdoor motion simulator, wherein both are connected to the digital control unit 200 for performance monitoring. In an embodiment, the simulated projectile launching mechanism 100 comprises a launching tube and a propulsion mechanism. The conventional object/weapon/explosive/propellant has been replaced with a hydraulically compressed and pneumatically locked spring to launch the projectile on electromechanical actuation. The effect of explosions, blasts and motions are simulated by combination of electro-pneumatic and audio-visual components. The launching tube comprises of a compressible spring which is configured to be locked along with the dummy projectile by means a hydraulic power pack and a pneumatic mechanism for holding it in a locked state. The lock release mechanism comprises of one pressure input unit, such as a compressor, cooperating with the launching tube. The mechanical propulsion system generates a predetermined high pressure to propel the projectile over a predetermined distance, upon pressing the trigger.

A first sensor, disposed within the launching tube, senses the unlocking of the spring and generates a spring unlocking signal which is transmitted to the control unit 200. The first sensor may be a contact-type or non-contact type sensor. Upon pressing of the trigger of the launching tube by the trainee, the pneumatic lock is released and upon receiving the spring unlocking signal, the control unit 200 activates audio-visual indications accompanied by a pneumatic blast at the rear of the launching tube. This also is accompanied by a means to simulate the flame.

The motion simulator 100 is communicatively coupled with the performance monitoring module 310.

The control unit 200 can be implemented as one or more microprocessors, microcomputers, digital signal processors, central processing units, state machines, logic circuitries, and/or any devices that manipulate signals based on operational instructions. Further, the control unit 200 is communicatively coupled with the motion simulator 100 and the performance monitoring module 310. The control unit 200 is configured to generate the launching instructions for the trainee upon receiving a command from the instructor, and is further configured to transmit the launching instructions to the performance monitoring module 310. It also can carry out additional functions such as digital video monitoring and processing, display of audio visual outputs pertaining to the performance of the trainees and transferring all the data thus collected to the performance monitor 310. The Control Unit 200 also can simulate emergency conditions to enhance the skills of the trainees. The command may also be given by an input device such as pressing a switch, by typing an instruction on an alpha- numeric device such as a keyboard, using other input devices such as a mouse-pointer, a stylus and so on, or simply by speaking out instructions in front of a microphone or any other futuristic technology.

Moreover, the camera unit 230 is disposed at the simulated projectile launching mechanism

100. The standalone and integrated optical tracking module 230 comprises of group of fixed and adjustable (pan, tilt and zoom) type of sensors. This module is communicatively coupled with the digital video monitor 220 and performance monitoring module 310. According to an embodiment, the performance monitoring module 310 includes a video monitoring module 220 which in turn is configured to analyze the video signal generated by the sensor unit 230 and is further configured to generate the required data set. The performance monitoring module 310 generates a report of the performance of the trainee based on the data set, the locking signal and the trigger signal, and other relevant data as may be obtained using other special-purpose sensors. The report can include performance parameters which include time corresponding to locking of the projectile in the simulated projectile launching mechanism, time corresponding to pressing the trigger and accuracy of the trajectory followed by the projectile towards the target. The report can be stored in a dedicated repository 250 cooperating with the performance monitoring module 310, and can be displayed on a screen visible to the instructor or can be configured for printing on a paper using a printer device cooperating with the repository 250 and the control unit 200.

The training system 1000 is also provided with an audio- visual module 130 cooperating with the performance monitoring module 310. The audio-visual module 130 outputs audio and visual signals corresponding to the launching instructions as well as a pre-recorded sound associated with launching of the projectile to simulate launching of the projectile based on the locking signal and the trigger signal. The audio- visual module 130 includes a speaker device for audio and a light-emitting device, selected from the group consisting of an incandescent bulb, a CFL lamp, an LED array and an LED screen, an LCD screen, an OLED screen and the like, which glow and/or display text or images when the input is operated by the instructor, to be visible to the trainee. The audio-visual module 130 also includes a speaker which outputs instructions given by the instructor in audio format. The instructions spoken into a microphone by the operator can be transmitted directly by the microphone, or if the instructions are input by the instructor in any non-audio form using any input device from those listed above, the speaker may output a pre-recorded audio corresponding to the instructions. After the projectile is launched along its trajectory, the control unit 200 is configured to play, through the audio-visual device 130, pre-recorded audio clips to simulate explosion, motion through the air and blast. Additionally, emergency conditions can be simulated during the training sessions to enhance safety consciousness and preparedness of the operator in actual scenario, by employing the audio- visual module 130 to simulate the scenarios. The control unit 200, with the various possibilities of input devices and methods, coupled with the audio-visual module 130, with its wide range of possible output means, is an effective aid which helps in training the instructor besides helping the operators in decisionmaking. The training system 1000 is also provided with a portable stand configured to receive at least a portion of the simulated projectile launching mechanism 100.

The launching tube can be mounted on the portable, extendable stand. According to an embodiment, the portable stand is 360 degree rotatable about a vertical axis.

A radium-coated compass rose is also provided around the portable stand. The radium-coated compass rose can have discrete or markings of angles at an interval of 30deg starting from 0° to 359°. The radium-coated compass rose enhances the situational awareness of the trainees/operators in terms of directional orientation. It can be effectively employed in any featureless terrain in both day and night.

In an embodiment, the training system 1000 comprises a crossover range transceiver 280 configured to facilitate communication between the control unit 200 and an operator station associated with a pair of a trainee and a corresponding instructor.

In another embodiment, the training system 1000 comprises a voice communication module 240 which facilitates transfer of voice signals from the control unit 200 to a voice recorder coupled to the launching system 1000.

In yet another embodiment, the training system 1000 comprises a built-in test equipment 220 which monitors health of the system and displays/records in the form of coding. It works in the wireless means of communication.

In still another embodiment, the training system 1000 comprises an indoor training unit 300. The indoor training unit 300 cooperates with the control unit 200. The indoor training unit 300 comprises a visor-mounted display unit 320, an orientation sensor, a computing and comparator module 340.

In an embodiment, the recorded visuals are stored in various photographic as well as videographic formats. The visor-mounted display unit 320 displays at least one combination of one each of the visuals of the plurality of terrains, the plurality of targets and the plurality of projectile motions and diurnal and weather changes to be experienced by the trainee. The orientation sensor senses three-dimensional orientation of the motion simulator for projectile launching mechanism 100, particularly the orientation of the launching tube, as the motion simulator for projectile launching mechanism 100 is held in hand or on shoulders or as mounted on the portable stand by the trainee. The orientation is measured in terms of angle in horizontal and vertical planes. The computing module 340 computes displacement of a projectile based on the orientation of the simulated launching tube. This displacement is measured in terms of distance travelled, i.e., range, although other parameters of the projectile motion such as initial velocity, time of flight, acceleration, velocity, parabolic trajectory maximum height and so on. The computing module 340 can also be configured to take earth's curvature into account while calculating the range. The comparator 340 is configured to compare the computed displacement by the computing module and displacement corresponding to the plurality of projectile motions stored in the repository 40 to determine the visuals of projectile motion to be displayed, based on the comparison. The control unit 200 is communicatively coupled with the repository 250. The control unit 200 is configured to transmit a combination of visuals of a terrain and a target from the repository 250 to the visor-mounted display unit 320 for displaying as per instructions received from the instructor, and transmit the visuals of the projectile motion from the repository 250 to the visor-mounted display unit 320 stored as determined by the comparator 340. Thus, the visor- mounted display unit 320, in combination with the speakers playing pre-recorded audio clips to simulate explosion, motion through the air and blast, simulate the field conditions such as a variety of terrains, for the trainee to be trained in an indoor training environment. Again, in case of the indoor training unit 300 as well, a trainee receives instructions from an instructor who transmits instructions through the inputs devices configured on the digital control unit 200. The training system 1000 may also be configured to provide a screen projecting realtime simulated projectile motion corresponding to the trainee's actions, to be observed or monitored by the instructor. In one embodiment, the training system 1000 employs a multisource power supply unit 400. In an embodiment, the power supply unit 400 includes one source or multiple sources of electricity viz. renewable energy such as solar energy, rechargeable batteries (9V and 12 V and similar), online UPS and petrol/diesel generators. All the powered modules and other components of the training system 1000 have been designed to operate in both wired and wireless modes. This provides flexibility for deployment in any kind of terrain and topography and also ensures uninterrupted operations.

The modular construction of the training system 1000 enables integration of different genre of simulators onto a single platform thus optimizing the resources. The training system 1000 comprises various standalone and integrated modules which are easily modifiable to match the specifications of similar equipment as per present or future requirements.
