Research on Cycle Slip Detection Algorithm for Beidou Triple-Frequency Carrier Pseudorange Combination
Abstract We are concerned with the characteristics of the triple-frequency signal broadcast by the full constellation of the Beidou navigation satellite system. One carrier pseudorange combination (1,4,-5) and two triple-frequency geometric-free phase combinations (1,1,-2) and (1,-2,1) perform the cycle slip detection. We combine the minimum 2-norm to the integer cycle-slip search strategy to determine the cycle-slip value. The measured data show that the proposed method can detect and repair the normal cycle-slip, insensitive cycle-slip and continuous random cycle-slip.
Key words :
BDS
cycle slip detection and repair
triple-frequency observation
