摘要
本文对卫星导航中的权重估算模型进行研究,通过分析卫星导航中的误差特点,利用有限数据建立误差的估算模型,在不消耗额外资源的同时得到卫星的权重,提高了卫星导航稳定性stability和可靠性。用软件实现估算模型并进行试验验证,证明了该估算模型的可行性和有效性。
The weight estimation model for satellite navigation is studied in this paper. A method which uses limited data to establish error estimation model is obtained by analyzing the characteristics of errors in satellite navigation. The method which gets the weights of satellites without consuming additional resources improves the stability and reliability of satellite navigation. The weight estimation model based on software has been made an experiment. The result shows that the weight estimation model is feasible and effective.
