APPARATUS OF COMPUTING THE PSEUDORANGE MEASUREMENT NOISE OF REFERENCE STATION RECEIVER FOR GNSS AUGMENTATION SYSTEMS AND METHOD THEREOF

摘要

An apparatus of computing the measurement noise of base station receiver is provided to calculate measurement noise preciously in measuring the pseudo range from the base station receiver. In an apparatus of computing the measurement noise of reference station receiver, a pseudo satellite signal generating unit(10) produces pseudo satellite signal including the satellite orbit, the ionosphere/ convection zone, and the satellite clock error information. A base station receiver(40) produces the native information including the pseudo range from the satellite by receiving pseudo satellite signal. A native information measurement noise analysis unit(50) calculates measurement noise in calculating the native information by using the native information from the base station and the signal state of the pseudo satellite.
