On-the-fly ambiguity resolution by restricting coordinates predicted by Doppler

  • The main difficulty of kinematic positioning using carrier phase observations is the ill-posed problem of normal matrix. The float ambiguity and its covariance matrix are inaccurate, so impact the success rate of ambiguity resolution. A new method was put forward for resolving the ill-posed problem in kinematic positioning by restricting the coordinates predicted by Doppler observations. The float ambiguity and its covariance matrix were improved because the coordinates predicted by Doppler were more accurate than that determined by pseudo-range observations, so the success rate of ambiguity searching was advanced. The results indicate that the effect of the new method for on-the-fly ambiguity resolution of the short baseline is clear.
