ABSTRACT:
A length of time required for the verification of data transmitted from a satellite or satellites is reduced. A distance r1 calculated from a time delay required for the propagation of a radio wave between a transmitting and a receiving site is obtained, as is a line-of-sight distance r2 which is calculated from the positions of a satellite and a point of reception. When a difference between these two distances is small, data from these satellites are regarded as valid data. However, when the difference is large, data is regarded as involving a large error. The position of the point of reception is determined by a positioning calculation which utilizes data from predetermined three or four verified satellites, or is entered by an operator. The position of the satellite is obtained from orbital data which is delivered by that satellite.
