| Abstract: | Instrument bias is one of the main error sources in determination of Total Electron Content using GPS measurements, the receiver instrument bias between P1 and P2 is called Differential Code Bias （DCB）. In this article, the algorithm of receiver DCB computation using GPS measurements is discussed and is implemented through software. The Results of actual observation data show the algorithm is correct. |
