New Data on Two Satellite Algorithms Without an Atomic Clock

Leonard R. Kruczynski, Anil Tiwari, Ralph F. Eschenbach

Abstract:	In a previous paper we discussed the use of two-satellite position fixing with GPS by using additional inputs such as LORAN TDs, speed and heading. In that paper we discussed some of the algorithms we have used and showed some very preliminary data. In this paper we present more extensive data showing some of the operation under dynamics as well as some of the performance when transitioning between different navigation measurement environments. This data shows a greatly extended navigation capability during the period when there are too few satellites for continuous 2-D navigation.
