Recent advances and perspectives in GNSS PPP-RTK

Measurement Science and Technology, 2023
Abstract Precise point positioning-real-time kinematic (PPP-RTK), otherwise known as integer ambiguity resolution-enabled precise pointing positioning, has attracted much attention in recent years and has become state-of-the-art in the global navigation satellite system (GNSS) high-precision positioning community.

Impact and mitigation of neglecting PPP-RTK correctional uncertainty

GPS Solutions, 2021
The 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, 2017
Japanese 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

2013
Integer 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

2016
In 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 ...
