Weight Determination and Accuracy Analysis of Combined GPS/BeiDou Single Point Positioning
摘要
Abstract
The Variance Component Estimation (VCE) method is used to determine the weight of observations from different satellite systems in the combined GPS/BeiDou single point positioning (SPP) .A proper observation weight ratio between GPS and BeiDou pseud-orange measurements is acquired .The positioning accuracy of combined GPS/BeiDou SPP is analyzed using both static data and kinematic data collected under open sky and blocked envi-ronment .The results indicate that the combined GPS/BeiDou SPP can significantly improve the positioning accuracy for both the static and kinematic tests over GPS-only SPP .关键词
