摘要
En 中文
The multipath effect often reduce global positioning system (GPS) positioning accuracy. Traditional GPS positioning methods usually ignore the multipath effect errors, resulting in poor positioning estimation accuracy. This article proposes a variable projection algorithm based on the Aitken method, which takes into consideration of the multipath effect error with the aim at improving the estimation accuracy, and uses the Aitken acceleration method to increase the convergence rate. In addition, the proposed method is robust to the step-size. Theoretical analysis and simulation examples show the effectiveness of the proposed method.
