Abstract :
Cross-correlation properties of the Global Positioning System (GPS) coarse acquisition (CA)-code can significantly degrade measurement performance for high precision applications. The use of semi-codeless P-code measurements of the Link 1 (L1) carrier signal for the mitigation of CA-code cross-correlation errors is investigated. The trade-off between cross-correlation error mitigation and squaring loss (SL) of the semi-codeless tracking is discussed. Test results are used to demonstrate the efficacy of using P-code measurements for the cross-correlation error mitigation.
