Improving Reliability and Assessing Performance of Global Navigation Satellite System Precise Point Positioning Ambiguity Resolution

Conventional Precise Point Positioning (PPP) has always required a relatively long initialization period (few tens of minutes at least) for the carrier-phase ambiguities to converge to constant values and for the solution to reach its optimal …

Examining the interoperability of PPP-AR products

Integer ambiguity resolution of carrier-phase measurements from a single receiver can be implemented by applying additional satellite products to mitigate the unmodeled satellite hardware delay. Interoperability of different PPP-AR products would …

Integer satellite clock combination for Precise Point Positioning with ambiguity resolution

While satellite clock combinations are routinely utilized within the IGS, they currently disregard the fact that some ACs provide integer clocks. Users have been expected to choose either a robust combined solution or select individual AC solutions …
