FIELD: radio engineering.
SUBSTANCE: signal in client transmitter of object is subjected firstly to time-pulse, then to phase modulation. At receipt stations signal is subjected to autocorrelation processing. On basis of differences in time delays of radio signal receipt object coordinates are determined. Signal is sent to space in the moment necessary for client by packets of 10 pulses with temporary shift of position of each pulse of packet. Each pulse consists of fixed binary phase-manipulated 512 digit M-series of elements, picked with consideration of minimal level of side leafs in frequencies band 5MHz. radio receipt is performed only by three stationary base stations. Temporary delays of radio signal receipt are determined at same stations. Time-pulse modulator is connected to code series generator via Gauss filter.
EFFECT: higher efficiency, broader functional capabilities.
