Satellite Bias Corrections in Geodetic GPS Receivers

D. Matsakis, S. Mitchell, E. Powers

Abstract:	As described in Hegarty et al. (2005), GPS reception can have nanosecond-level biases as a function of satellite and receiver setting, and these could also vary between individual units even when observing the same signals. The bias problem is made even more complicated by the fact that all manufacturers don’t infer their ionosphere corrections with the same signal set. Although bias correction tables exist, and are often implemented, individual receiver differences remain an issue. This paper presents the observed satellite biases of three different geodetic receiver models utilized at two facilities of the US Naval Observatory.
