Abstract

This paper presents a vector tracking loop (VTL)-based carrier tracking algorithm assisted by desired trajectory of vehicles during short signal outages. The VTL-based carrier tracking algorithm is first derived. The desired trajectory of vehicles is then introduced to assist the VTL, ensuring that the carrier numerically controlled oscillator (NCO) keeps working during signal outages. The performance improvement of the proposed algorithm is verified in two different scenarios. It is shown that the VTL assisted by desired trajectory has higher frequency precision than that with no assistance. Besides, the proposed method can maintain the navigation solving and restrain the frequency error from increasing.
