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

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 ...

A decentralized algorithm for generating PPP-RTK network products

2023
PPP-RTK, a synthesis of the well-known precise point positioning (PPP) and real-time kinematic (RTK) techniques, requires precise satellite-related products and atmospheric corrections estimated in a global navigation satellite system (GNSS) network. For generating these products, one commonly sends all network data to a computation center and conducts

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 ...

Improving PPP-RTK with a Self-validation Grid-Based Ionospheric Model

2023
The rapid convergence of PPP-RTK depends on the ionospheric correction including the accuracy and prior information. However, the traditional grid-based ionospheric model often uses fixed ionospheric prior information without taking into account the spatiotemporal diversity of the ionosphere, thus weakening the performance of PPP-RTK and limiting its ...
