A simple combination procedure for a more economical processing of code tracking and carrier phase measurements obtained from the GPS Navstar Satellites is presented. The position processing algorithms are simplified by combining code measurements with integrated Doppler measurements into a combined pseudorange...

Recently, direct acquisition of GPS P-code has received considerable attention to enhance the anti-jamming and anti-spoofing capabilities of GPS receivers. This paper describes a P-code acquisition method that uses block searches with large-scale FFT to search code phases and carrier frequency offset...
In this work, we consider multipath error estimation as a regression problem and propose a unified framework for both code and carrier-phase multipath mitigation for ground fixed GPS stations. We use the kernel support vector machine to predict multipath errors, since it is known to potentially ...
