SATELLITE NAVIGATION SYSTEM FOR DETECTION OF OBJECT POSITION Russian patent published in 2000 - IPC

FIELD: navigation systems using differential correction methods. SUBSTANCE: method involves reception of navigation signal, which is emitted by each of accessed navigation satellites of main or additional orbiting sets, simultaneously by means of antenna-feeder devices of navigation equipment, reference transmitter-receiver and integral monitoring device, which belong to monitoring correction station. Monitoring correction station contains following functional parts: reference receiving-transmitting device, which detects real value of differential corrections and broadcasts information about differential corrections for user's equipment, integral monitoring device, which monitors broadcasting of navigation signals from accessed satellites and differential correction signal, measures precision of transmitted value of differential correction by means of parallel detection of position of monitoring correction station taking into account received differential correction and their subsequent comparison to known coordinates of monitoring correction station. In addition, it achieves control of operation modes of monitoring correction station and its testing using simulator of navigation satellite signals. In addition, monitoring correction station has data recorder, which detects and stores basic parameters of its operations, redundant equipment, which has complete set of monitoring correction station in hot state. EFFECT: possibility of continuous monitoring of navigation fields, generation of information about integrity of navigation data, increased fidelity of detection of object position using redundant number of navigation satellites. 1 dwg
