Paper Abstract
When the Anti-Spoofing (A-S) is active, the civilian users have some difficulties in using the P(Y) code for precise
navigation and positioning. Z-tracking technique is one of the effective methods to acquire the P(Y) code. In this paper,
the accuracy of pseudoranges from C/A code and P(Y) code for dual frequency GPS receiver is discussed. The principle
of measuring the encrypted P(Y) code is described firstly, then a large data set from IGS tracking stations is utilized for
analysis and verification with the help of a precise point positioning software developed by authors. Especially, P(Y)
code pseudoranges of civilian GPS receivers allow eliminating/reducing the effect of ionospheric delay and improve the
precision of positioning. The point positioning experiments for this are made in the end.
