摘要： 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.

摘要： A relative speed of a vehicle with respect to a satellite is detected from a deviation of a tuning frequency caused by the Doppler effect, and a vehicle speed is determined from the relative speed. A piezoelectric oscillation gyro detects an angular speed of rotation of the vehicle, which is integrated to determine an azimuth. A travel is detected in terms of the vehicle speed and the azimuth, and the detected travel and information from available GPS satellites are substituted into a navigation equation to solve it for a solution. Alternatively, altitude information detected by an altitude sensor and the angular speed of rotation of the vehicle as detected by the piezoelectric oscillation gyro may be is inputted. The angular speed of rotation is integrated to determine the azimuth. Information from two GPS satellites and information representing azimuth .phi. and altitude .DELTA.z are substituted into the navigation equation to solve it for a solution. Kalman filter is employed. Even when available GPS satellites is two or one, the determination of the position of the vehicle is enabled. The need for a vehicle speed sensor is eliminated, and the accuracy of positioning is enhanced.
