✦ Synopsis
The kinematic global positioning system (GPS) is a system that successively executes the positioning of a mobile user with the accuracy of several centimeters by measuring the phase of the radio wave (carrier) from the GPS satellite while moving. A problem in the kinematic GPS system, however, is that the phase-shift corresponding to the integer multiple of the wavelength (cycle slip) produced during the phase measurement must be eleminated to realize a highly accurate positioning.
For this problem, this paper presents a method that can detect and eliminate the cycle slip with a high accuracy and robustness by more than four GPS satellite signals which is needed in the positioning. The detection/elimination of the cycle slip based on the update residual error of the Kalman filter and the detection/ elimination of the cycle slip based on the redundant GPS signal are integrated and a method to determine the cycle slip with a high accuracy is realized.
