A Novel Un-Differenced PPP-RTK Concept [PDF]

Journal of Navigation, 2011
In this contribution, a novel un-differenced (UD) (PPP-RTK) concept, i.e. a synthesis of Precise Point Positioning and Network-based Real-Time Kinematic concept, is introduced. In the first step of our PPP-RTK approach, the UD GNSS observations from a regional reference network are processed based upon re-parameterised observation equations ...

PPP-RTK and Inter-System Biases: The ISB Look-Up Table as a Means to Support Multi-System PPP-RTK [PDF]

Journal of Geodesy, 2016
PPP-RTK has the potential of benefiting enormously from the integration of multiple GNSS/RNSS systems. However, since unaccounted inter-system biases (ISBs) have a direct impact on the integer ambiguity resolution performance, the PPP-RTK network and user models need to be flexible enough to accommodate the occurrence of system-specific receiver biases.

Ground-based PPP-RTK for pseudolite systems

Journal of Geodesy, 2021
Global navigation satellite systems (GNSS) can provide high-accuracy positioning services in the open environment, while they have poor performance in shadowed regions. Pseudolite (PL) systems, with flexible deployment, can carry on the role of GNSS to provide high-accuracy positioning services in the case of GNSS failure.

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.

On the Feasibility of Instantaneous Multi-GNSS Multi-Frequency PPP-RTK

2023 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2023
Ambiguity 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.
