BDS短基线单历元差分定位算法
A BDS Single-Epoch Differential Positioning Algorithm for Short Baselines
摘要
Abstract
Aiming at the serious ill-posed problem of double-difference equations in BDS short baseline single epoch differential positioning,we use the TIKHONOV regularization criterion to improve the ill-posed problem,and then obtain the reliable floating point solution and its corresponding variance covariance matrix.The partial ambiguity fixed strategy,using the LAMBDA method to obtain an accurate fixed solution,is then applied to achieve centimeter results in BDS real-time positioning.关键词
