A method to assess the quality of GNSS satellite phase bias products GPS Solut. (IF 4.9) Pub Date : 2024-03-25
Abstract As part of the International GNSS Service (IGS), several analysis centers provide GPS and Galileo satellite phase bias products to support precise point positioning with ambiguity resolution (PPP-AR). Due to the high correlation with satellite orbits and clock offsets, it is difficult to assess directly the precision of satellite phase bias products. Once outliers exist in satellite phase

A comparison of two PPP-RTK models: S-basis choice, network product precision, and user positioning performance GPS Solut. (IF 4.9) Pub Date : 2024-03-25
Abstract PPP-RTK combines the advantages of both precise point positioning (PPP) and real-time kinematic (RTK) techniques. While constructing PPP-RTK models based on undifferenced and uncombined observations offers apparent benefits, these observation equations suffer from a rank deficiency issue. To address this problem, the Singularity-system (S-system) theory can be utilized. This theory imposes

Abstract Precise Point Positioning-Real Time Kinematic (PPP-RTK), a synthesis of PPP and RTK techniques, is a highly precise positioning technique that has been extensively studied in the GNSS community. The Zenith Wet Delay (ZWD), an important estimated parameter in PPP-RTK, significantly impacts the user positioning performance. It is crucial to determine the optimal ZWD processing methods for PPP-RTK
