Review on vector tracking application to GNSS receiver

GNSS receiver based on vector tracking loop joints information from all channels to estimate user's position, velocity and time. In vector mode, signal tracking block and navigation processor are coupled together, so all channels can transmit and share information. The actual satellite ephemeris is adopted to verify the performance of tracking loop. Compared to STL, VTL improves weak signal tracking, anti-jamming ability and rapid signal recovery after a satellite blockage. This paper describes the development of vector tracking, vector tracking loop architecture, system modeling and algorithm. Major applications are summarized in terms of vector tracking. The aim of this review paper is to provide an extensive overview of existing vector tracking research and a guide for development in the future.
