Design and implementation of dual-mode four frequency vector receiver

This paper studies the application of vector tracking algorithm in GPS and BDS receiver with the high speed. Firstly, it proposes an architecture of GNSS receiver with four frequency. Secondly, it expounds transfer and measurement equation of vector tracking navigation filter. Then it briefly compares and analyzes performance and positioning accuracy of four frequency vector GNSS receiver with normal GPS receiver within a simulant scenarios of first cosmic velocity scenarios, and results show that the vector tracking technology has obvious advantages and applications for ground in this complex environment.
