GPS Phase Estimation Beyond the Maximum Likelihood Theory

Mohamed Youssef and Phani K. Sagiraju

Abstract:	This paper analyzes errors found on pseudorange and delta range measurements that have been initiated as a code/carrier phase measurements due to multipath and deep attenuation. The objective of this paper is to draw some practical observations and to come up with a methodology that distinguishes between the impacts of deep attenuation versus multipath. With such knowledge, a GPS receiver can execute in a real time the right impairment mitigation technique.
