Definitions

  • This invention relates generally to airborne projectiles having navigation capabilities and, more particularly, to airborne projectiles having radio based navigation systems to provide position data and a self-destruct feature which causes the projectile to self-destruct when the missile enters undesirable airspaces.
  • a typical missile may have any one of a number of targeting systems known to those skilled in the art.
  • ground-to-ground missiles such as cruise missiles, one type of which is the Tomahawk Missile
  • AMRAAM Digital Scene Mapping
  • Some surface-to-air missiles also use radar guidance systems to lock on to airborne targets.
  • some air-to-ground missiles use radar or laser based guidance systems to home in upon a target illuminated by a laser signal.
  • US Patent No. 5,689,420 discloses a range safety tracking and data processing system for airborne vehicles, which can trigger an onboard destruct package when it is determined that the global position of a vehicle violates certain Range Safety parameters.
  • This invention is directed to a self-destruct apparatus for an airborne projectile.
  • the apparatus includes a navigational system which determines the position of the projectile.
  • the apparatus also includes memory for storing a plurality of positions. Some of the plurality of positions are designated as acceptable positions for the projectile, and others of the positions defined as unacceptable positions for the projectile.
  • An electronic control unit searches for a location in memory which corresponds to the position determined by the navigation system to determine if the position of the projectile is acceptable or unacceptable.
  • the electronic control unit initiates a self-destruct signal which causes the projectile to self-destruct if the position of the projectile is unacceptable.
  • FIG. 1 is a block diagram of an electronic control system 10 for a projectile 8.
  • the electronic control system 10 includes an electronic control unit 12.
  • the electronic control unit 12 receives navigational information from a navigation system 14.
  • the navigation system 14 includes an antenna 16.
  • the antenna 16 receives electromagnetic signals 18 radiated by an electromagnetic transmitter, such as satellite 20.
  • An example of such a satellite 20 may be found with reference to one or a plurality of satellites 20 such as are found in a Global Positioning System (GPS), any ground-based electromagnetic transmitters such as may be found in a LOng RANge (LORAN) navigation system, or any other system known to those skilled in the art.
  • GPS Global Positioning System
  • LORAN LOng RANge
  • the antenna 16 provides electronic input signals to the navigation system 14 in accordance with the received electromagnetic signals 18.
  • the navigation system 14 may be an inertial type navigation system.
  • the navigation system 14 determines the position of the projectile 8. For example, the navigation system 14 may determine the position of the projectile 8 by determining the latitude and longitude in accordance with the electromagnetic signals 18 received from the one or a plurality of satellites 20. The navigation system 14 may also determine speed and bearing information of the projectile 8 as well. The navigation system 14 outputs this information to the electronic control unit 12. The electronic control unit also communicates with a memory 24.
  • the memory 24 typically stores a table of acceptable and unacceptable latitude and longitude coordinates. The latitude and longitude coordinates provide indices to the table locations. The memory locations corresponding to the latitude and longitude indices define acceptable and unacceptable positions of the projectile 8.
  • the electronic control unit 12 reads the memory location in accordance with the latitude and longitude coordinates provided by navigation system 14. If the coordinate position of the projectile 8 is acceptable in accordance with the table stored in memory 24, the electronic control unit 12 continues to provide guidance information to control the flight path of the projectile 10. If the memory location 24 indicated by the latitude coordinate location output by navigation system 14 is unacceptable as determined by the table stored in memory 24, the electronic control unit provides a signal to a self-destruct system 26.
  • FIG. 2 shows an exemplary table 30 which may be stored in the memory 24.
  • the inputs to the table can be found along the upper row and left column of the table.
  • Each row defines a coordinate latitude
  • each column defines a coordinate longitude.
  • an A indicates an acceptable position for the projectile 8
  • a U indicates an unacceptable position for the projectile 8.
  • Each latitude and longitude coordinate position preferably defines boundary points of acceptable and unacceptable positions.
  • the latitude and longitude coordinates output by the navigation system 14 are then matched to the latitudes and longitudes found in table 30 by associating each latitude and longitude coordinate position output by navigation system 14 with the nearest latitude and longitude found in the table 30. In this manner, entire areas can be designated as acceptable or unacceptable positions for the projectile 8.
  • the right column of table 30 also could be used to determine altitude, if desired. In this matter, three inputs, latitude, longitude, and altitude cooperate to determine acceptable and unacceptable positions of the projectile 8.
  • FIG. 3 depicts a plan view of operation of the electronic control system 10 to operate the self-destruct system 26.
  • a plane 36 launches a missile 38 in a geographical boundary defined as a no-fly zone 40.
  • the missile 38 receives electromagnetic signals 18 from satellite 20. As described with respect to FIG. 1, these signals provide navigational information to determine the coordinate position of the missile 38.
  • the path of the missile 38 is indicated by arrow 42. If the missile 38 goes beyond the boundary of no-fly zone 40, indicated in phantom, the missile 38 may enter the territory of a neutral country 44 or a non-combatant country 46. In order to prevent the missile 38 from entering either of these countries, table 30 of FIG.
  • the missile 38 is arranged so that the missile 38 self-destructs when it reaches the boundary of the no-fly zone 42. This prevents the missile 38 from entering the airspace of the neutral country 44, the non-combatant country 46, or the friendly country 48 and greatly improves the safety and operation of the missile 38.
  • the present invention enables the safe use of projectile 8, such as rockets or missiles, by including navigational instrumentation in the electronic control portion of the projectile 8.
  • the electronic control portion thus determines if the projectile 8 is located in an acceptable position as determined by latitude, longitude, and/or altitude. If the rocket is in an unacceptable coordinate location, the rocket self-destructs in order to prevent the missile from striking inadvertent targets.
