The Preliminary Results for Five-System Ultra-Rapid Precise Orbit Determination of the One-Step Method Based on the Double-Difference Observation Model
TL;DR: The double-difference observation model of five-system ultra-rapid precise orbit determination; based on a one-step method; is derived and embedded into Bernese v5.2; thereby forming a new prototype software platform.
Journal ArticleDOI
Galileo real-time orbit determination with multi-frequency raw observations
TL;DR: Real-time GNSS orbit determination with multi-frequency raw observations is feasible and extendable with proper treatment of IFCB, indicating a loose correlation between these two parameters.
Journal ArticleDOI
Assessment of the GNSS PPP performance using ultra-rapid and rapid products from different analysis centres
TL;DR: The performance of precise point positioning (PPP) mainly depends on satellite orbit and clock accuracy, and ultra-rapid and rapid orbit/clock products have been creating by analysis centres for this purpose.
