Impact and mitigation of neglecting PPP-RTK correctional uncertainty
GPS Solutions, 2021The corrections needed to realize integer ambiguity resolution-enabled precise point positioning (PPP-RTK) at a single-receiver user are often treated as if they are deterministic quantities. The present contribution aims to study and analyze the effect the neglected uncertainty of these corrections, which are subject to time delay, has on the PPP-RTK ...

SSR Assist for Smartphones with PPP-RTK Processing
ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2017Japanese Quasi-Zenith Satellite System (QZSS) provides the Centimeter Level Augmentation Service (CLAS) using Compact State Space Representation (SSR) correction data. It enables Precise Point Positioning (PPP) in Real-Time Kinematic (RTK) networks. This method is called PPP-RTK GNSS positioning, which realizes centimeter-level positioning accuracy and

Single-Frequency PPP-RTK: Theory and Experimental Results
2013Integer ambiguity resolution enabled Precise (cm-level) Point Positioning (PPP) is feasible if corrections from a GPS network of CORS stations are applied to the single-receiver phase and code data of a user. The concept of PPP-RTK requires a proper definition and quality of the PPP-user network corrections, which are satellite clocks, satellite phase ...

Multi-GNSS PPP-RTK: Mixed-Receiver Network and User Scenarios
2016In this contribution, we present full-rank observation equations of the network and user receivers, of mixed types, through an application of S-system theory. We discuss the important roles played by the inter system biases (ISBs), and we show how the three-component structure of PPP-RTK is affected by the inclusion of the ISBs as extra parameters in ...
