Analysis Method of Code Tracking Performance for GNSS Signals Based on Generalized Tracking Loop
摘要
Abstract
Code tracking performance assessment method based on the generalized tracking loop is presented,which extends traditional code tracking theory and provides generalized theoretical expressions of code tracking variance for matched and un⁃matched tracking algorithms.Theoretical results take into account signal modulation, receiver setup ( e. g., front⁃end bandwidth, early⁃late spacing, integration time and loop bandwidth),tracking algorithms(e.g.,matching processing and single side band processing),noise and inter⁃ference.Analytical analysis is supported by test results of BOC and MBOC signals,which is compatible with matched and un⁃matched algorithms and provides a comprehensive view of code tracking performance for GNSS signals.关键词
