PCT No. PCT/SE97/01566 Sec. 371 Date Mar. 18, 1999 Sec. 102(e) Date Mar. 18, 1999 PCT Filed Sep. 16, 1997 PCT Pub. No. WO98/12687 PCT Pub. Date Mar. 26, 1998A device for simulating in real-time a path of an object in a three-dimensional coordinate system. The device includes at least a first unit and a second unit each provided with a GPS receiver for receiving position and timing signals respectively from at least four GPS satellites, a transmitter/receiver for communication between the first unit and the second unit in the VHF or UHF frequencies, and a communication computer having memory capacity and providing a connection between the GPS receiver and the transmitter/receiver. A simulation computer is included at least with the first unit. The simulation computer communicates with the communication computer and simulates with an event driven protocol a path in the coordinate system of the object and communicating the path to the second unit. The communication computer controls the communication through the transmitter/receiver according to an STDMA method. |
