Doppler Processing for Satellite Navigation

Conference Proceeding

Publication Date



Doppler processing was the principle of operation for the first satellite navigation system, Transit, that became operational in 1964 and was phased-out in 1996 [1]. Its successor, the Global Positioning System (GPS) uses the principle of one-way ranging, which requires fewer satellites for a position solution compared to Doppler processing [2]. In recent years, Doppler processing has been revisited for several applications, including precise velocity [3]; positioning with low earth orbit (LEO) satellites using carrier Doppler shift only [4]; combining signal-of-opportunity Doppler measurements from multiple LEO satellite constellations [5]; and solutions combining both pseudorange and Doppler measurements [6]. This paper summarizes different Doppler processing techniques, performance as a function of geometry and error sources, and provides results for several examples ranging from computer models to actual observations from static and dynamic users.
