摘要
文中提出了一种利用伪卫星测距信息和惯导测量量相结合进行平面定位与授时的算法。该算法不仅可以在很短时间内估计出惯导定位误差、接收机与伪卫星基站间的时间不同步量,且所估计出的定位误差和时间不同步量的精度均可达到与测量噪声相同的量级。文中对所提出的算法进行了计算机仿真,仿真结果证明了该算法的正确性和实用性。
This paper proposes a new algorithm that can achieve plane positioning and time-transfer by the measurement information of pseudolites and INS. Using this algorithm, we can estimate the error of INS positioning and the time offset between the user receiver and pseudolite stations. Furthermore, the precision of positioning and time-transfer can reach the corresponding magnitude with measurement noise. In addition, the validity and practicability of the proposed algorithm has been proved by the simulation results.
