RISEffect of Temporal Physical Correlation on Accuracy Estimation in GPS Relative Positioning
Publisher: American Society of Civil Engineers
Abstract: Generally, in global positioning system (GPS) carrier phase relative positioning, the mathematical model does not describe the observations completely. This is mainly due to the lack of information about the physical ...
Efficient Algorithm for Inverse of the Fully Populated Covariance Matrix in Global Positioning System Relative Positioning
Publisher: American Society of Civil Engineers
Abstract: Stochastic modeling of the global positioning system (GPS) residual errors yields a fully populated covariance matrix for the GPS carrier phase double difference observations. Implementing this fully populated covariance ...
Efficient Between-Satellite Single-Difference Precise Point Positioning Model
Publisher: American Society of Civil Engineers
Abstract: This paper describes a new model for precise point positioning (PPP), which overcomes the drawbacks of existing PPP models. This model is based on between-satellite single-difference (BSSD), which cancels out the receiver ...
