Recent advances and perspectives in GNSS PPP-RTK
Measurement Science and Technology, 2023Abstract 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.

On the Feasibility of Instantaneous Multi-GNSS Multi-Frequency PPP-RTK
2023 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2023Ambiguity resolution enabled precise point positioning (PPP-RTK) immediately provides centimeter-level positioning information, once the carrier phase ambiguities are correctly resolved. With the ongoing GNSS development and modernization, a steadily growing number of satellites can be observed on multiple signal bands.

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

Improving PPP-RTK with a Self-validation Grid-Based Ionospheric Model
2023The 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 ...

A decentralized algorithm for generating PPP-RTK network products
2023PPP-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
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 ...
