Abstract


In view of the low precision of the pseudo code ranging, the carrier ranging and the ambiguity of the whole week, the observation is very difficult, a method using carrier smoothing pseudo range measurement is proposed. The method of using carrier phase measurement values to improve carrier ranging pseudo code ranging precision, and at the same time, pseudo code ranging can lock the auxiliary carrier phase, improve the efficiency and accuracy of carrier phase observation, meet the requirement of real-time system. In the end of the paper, the simulation results show the improvement of the carrier smoothing pseudo range to the pseudo range observation.

Keywords


Pseudo code ranging, Carrier ranging, Carrier smoothing pseudo range.
