Abstract

To generate accurate correction data, DGNSS reference receiver should have capability to minimize the error of code and carrier phase measurements provided by delay and phase lock loop. The reason is that the correction data generated by DGNSS reference receiver include the measurement error, which is one of the non-common errors incapable of elimination on differential technique. In this paper, the optimal narrow loop noise bandwidth is derived for minimizing the error of raw measurements provided by delay and frequency lock loop of DGNSS reference receiver. This paper carries out the theoretical analysis of the derived loop noise bandwidth. Finally the analysis results are verified by the experiment using software receiver.
