A Simulation Result of Time Difference Estimation Between GNSSs for Generation of Differential Correction

Abstract

As more GNSS became available besides GPS, there is a growing need to con-vert DGPS into DGNSS. In this paper, we proposed a method to estimate the time difference between GNSSs at the DGNSS reference station. And we per-formed a simulation to verify the proposed method and presented the results of estimating the set time difference. In addition, we used estimated time difference to calculate the correction, and found that the bias of the correction can be re-moved.
