METHOD CONTROLLING POSITIONS OF MOBILE OBJECTS, FOR INSTANCE, ROLLING STOCKS, AND SYSTEM FOR ITS REALIZATION ( VERSIONS ) Russian patent published in 1998 - IPC

FIELD: control of relative positions of rolling stocks. SUBSTANCE: signals from navigation satellites are received on mobile object and at master station, distances from proper navigation satellites are measured on mobile object and at master station, signals from navigation satellites are received at least on two mobile objects, distances from proper navigation satellites are measured on mobile objects and received parameters are re-emitted, signals emitted from mobile objects are received at master station and coordinates, velocities of mobile objects and distance between them are found for each group of objects by same navigation satellites. Signals emitted from master station carrying information on coordinates, velocity and distances between objects are received on mobile objects. Versions of system controlling positions of mobile objects include master station with receiving antennas, receivers, computation unit, modulator, demodulator, control unit, transmitter and transmitting antenna, K mobile objects each carrying receiving and transmitting antennas, receivers, computation unit, modulator, control unit, demodulator, transmitter. EFFECT: enhanced precision in determination of distances between mobile objects. 3 cl, 7 dwg
