RECEIVING EQUIPMENT FOR MEETING WHOLE ATTITUDE OF FLYING BODY

摘要

PROBLEM TO BE SOLVED: To meet the whole attitude of a flying body by providing a plurality of global positioning system(GPS) antennas at opposite positions on the surface of the flying body and by subjecting a reception signal of each antenna to signal processing separately. ;SOLUTION: A plurality of GPS antennas 1 and 2 are provided at opposite positions on the surface of a flying body. Lead-in wires led out from the antennas 1 and 2 are not connected directly, but are separated, and GPS reception signals are subjected to signal processing separately. In more detail, each of GPS receivers 3A, 3B, 4A and 4B executes front-stage processing of signal waves transmitted from a GPS satellite and a ground reference station and outputs raw measuring data. A navigational computation processing part 5 executes generalized computation processing of these raw measuring data and determines pseudo-range(PR) measuring data, delta range measuring data and other computation data. Since the reception signals from the antenna 1 and 2 in a plurality are separated and subjected to the signal processing separately in this way, no phenomenon of multipass takes place.;COPYRIGHT: (C)1997,JPO
