A Fast Fixed Algorithm of GPS Single Epoch Ambiguity Resolution Based on DUFCOM and DC Algorithms

  • In order to solve the problem of low efficiency in high frequency GPS real time data processing when the number of observed satellites exceeds 6-8 while using the DUFCOM method,combining DC algorithm with the advantage of extremely high efficiency,a fast fixed algorithm of GPS single epoch ambiguity resolution by screening and classifying processing for the observed satellites is proposed.The results from the example show that the fast fixed algorithm could avoid the influence of resolution efficiency of double-difference integer ambiguity for the second-level satellites acting on first-level satellites,which improve the efficiency for ambiguity resolution greatly,and achieve the aim to high frequency GPS real time kinematic data processing.
