METHOD DETERMINING COURSE ANGLE AND COORDINATES OF LOCATIONS OF OBJECTS BY RADIO SIGNALS OF SPACECRAFT OF SATELLITE RADIO NAVIGATION SYSTEMS Russian patent published in 1998 - IPC

Abstract RU 2110077 C1

FIELD: space radio navigation and geodesy. SUBSTANCE: navigation radio signals of satellites are received by each of four antenna and receiver devices installed on objects. In this case antennas of these antenna and receiver devices form rectangular system of coordinates which axes are parallel to axes of objects. Pseudoranges are found, differences of ranges are determined by way of their mutual subtraction, coordinates of location and course angle are also calculated. Navigation radio signals of one and same satellite are received simultaneously by each antenna and receiver device. Increments of ranges are calculated by measurement of increments of phases caused by Doppler shifts of carrier frequency over measured interval with use of phase autoadjustments of frequency and differences of increments of ranges in mutually orthogonal bases are determined by way of mutual subtraction of measured increments of phases. EFFECT: improved authenticity of method. 1 cl, 2 dwg
