Performance analysis of atmospheric constrained uncombined multi-GNSS PPP

The general objective of this study is to analyze the performance of Precise Point Positioning (PPP) convergence and initialization while stochastically constraining the atmosphere. One specific objective of this study is to review the performance of …

Assessing the accuracy of PPP

The Precise Point Positioning (PPP) GNSS data processing technique has developed over the past 15 years to become a standard method for growing categories of positioning and navigation applications. The technique relies on single receiver point …

Do we need ambiguity resolution in multi-GNSS PPP for accuracy or integrity?

With the advent of quad-constellation, triple-frequency and external atmospheric constraints being provided to the PPP user, the novelty and focus of this paper is in the quest to answer the question: Do we really need ambiguity resolution in …

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 …

Integrity Monitoring for Precise Point Positioning

The Precise Point Positioning (PPP) GPS data processing technique has developed over the past 15 years to become a standard method for growing categories of positioning and navigation applications. This includes but is not limited to crustal …

Reduction of Precise Point Positioning Convergence Period

Precise Point Positioning (PPP) has become a popular technique to process GNSS receiver data by applying precise satellite orbit and clock information, along with other minor corrections. Although PPP presents definite advantages such as operational …

Relative Positioning Using RTK Measurement Filtering and PPP

Typical RTK performance is limited to baselines of

On the use of Network RTK to Replace Static Relative Positioning for Geodetic GPS Surveys

It has become a trend to replace the traditional single baseline RTK approach by using network RTK services, whilst there is still lack of authoritative guidelines and specifications with this most recent development of GNSS positioning. For this …
