RECEPTION INDICATOR Russian patent published in 1996 - IPC

FIELD: radio navigation. SUBSTANCE: invention may find use for location of mobile onjects. Reception indicator has receiver 1, former 2 of characteristics point, first quantizer 3, intermediate storage 4, main storage 5, computing unit 6, timer 7, second quantizer 8, detector 9 of stop, speed pickup 10, multiplier 11, adder 12, threshold unit 13, program unit 14, permanent storage 15, path meter 16, second timer 17. In case of fade or failure of signals becuase of screening there is conducted assessment of possible drift of gates of automatic tracking system. If assessment does not exceed band of drawing-in of system of resolution of ambiguity of phase readings then operational mode of reception indicator is maintained. In opposite case reception indicator is transfered into mode it was before search and assessment of drift of gate of automatic tracking system is compared with band of drawing-in of system before search. EFFECT: enhanced speed of response by reduction of time of repeat determination of location. 16 dwg
