The performance assessment of Precise Point Positioning (PPP) under various observation conditions
Measurement: Journal of the International Measurement Confederation, 2021Abstract Two different methods, absolute and relative positioning, are used in determining point positions with GNSS techniques. Precise Point Positioning (PPP) technique, which is one of the absolute positioning methods, is a powerful position determination method.

Assessment of Ionospheric Correction Behavior for Use with Precise Point Positioning (PPP)
The International Technical Meeting of the The Institute of Navigation, 2021Stanford and Hexagon performed this analysis to assess the accuracy and behavior of ionospheric corrections provided for use with Precise Point Positioning (PPP). In particular we are interested in the achieved level of precision as a function of ionospheric state, reference correction message latency, and network location and coverage.

Fixed ambiguity Precise Point Positioning (PPP) with FDE RAIM
Proceedings of the 2012 IEEE/ION Position, Location and Navigation Symposium, 2012Precise Point Positioning (PPP) has been one of the major research interests in the Global Navigation Satellite System (GNSS) research field in recent years. PPP is a promising method because it can provide centimeter level positioning accuracy by using only one GNSS receiver, without using local reference networks.

Real-Time Precise Point Positioning (RT-PPP) for Positioning and Mapping
2018Real-Time Precise Point Positioning (RT-PPP) has started to develop among Global Positioning System (GPS) community due to some reasons, such as reference stations are required, very economical and easy to operate from everywhere. By using a dual-frequency receiver with the support from GPS precise products, RT-PPP has proven to give centimetre to ...
