A Study of DGPS Performance in Case of Limited Bandwidth Availability

Abstract:	In general, a Reference Station calculates differential corrections which are valid for that exact location (zero baseline) at that particular epoch (age of corrections zero). Some of the errors compensated for by the Reference Station vary with space and time, namely satellite ephemeris, tropospheric and ionospheric errors. Therefore, the corrections calculated at the Reference Station suffer certain accuracy degradation as the separation distance increases and the corrections become too old. In this paper the accuracy of a DGPS system in case of a delayed time of the received corrections has been investigated and analysed in different scenarios and conditions.
