Velocity estimation based on satellite dual frequency EBPSK system
Zeyuan Lu, Lenan Wu, Zhang Yudong · 2014
To achieve accurate velocity estimation, the Dual EBPSK system model is proposed. EBPSK modulation is high in transmission efficiency. Two independent velocity estimation methods in the Dual EBPSK system are presented. Two velocity estimation results can be fused to get more accurate estimation. The validation of the two methods is proven by following analysis and comparison. Typical error in satellite positioning is analyzed. The validation of the proposed system is proven by the comparison.
