Analyze of the pseudorange noise error for compass B1 open signal based on the receiver

Abstract

Pseudorange noise error has a strong correlation with the parameters of receiver's antenna and RF, the technology of baseband signal processing. The pseudorange noise error of GNSS system should be analyzed based on the actual parameters of the receiver. In this paper, the relationship between the pseudorange noise error and the code tracking error of the receiver was first analyzed, the linear model of code loop was established, the process of non-coherent code tracking error was derivated, a new analysis method of pseudorange noise error was proposed based on the receiver. Then, the pseudorange noise error of Compass B1 open signal was analyzed based on the Compass universal receiver. The experiment showed that the analysis result for pseudorange noise error was correspond with the actual value, and the analysis method can provide a reference for GNSS system UERE budget. © 2013 Springer-Verlag Berlin Heidelberg.
