Instantaneous ambiguity resolution for URTK and its seamless transition with PPP-AR

GPS Solutions, 2014
We extend the current Undifferenced network RTK (URTK) approaches by additionally using P1/CA augmentation information from reference stations. P1/CA augmentation information can shorten the convergence time and help to fix the ionosphere-free combination ambiguities in several epochs.

ARIADNE with Ambiguity Resolution: Visual Marker Based Rapid Initialization of PPP-AR

2018 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2018
Precise Point Positioning (PPP) offers advantages over Real-Time Kinematic (RTK) positioning in that it needs no ground base station or a rover to provide a communication channel with the base station. Therefore, PPP is expected to be applied in various fields, such as precise agriculture, intelligent transportation, construction, and mining. One major

Analysis of GPS-DCM Clock Corrections in Support of 1Hz PPP-AR Applications

The International Technical Meeting of the The Institute of Navigation, 2019
Decoupled-Clock Model (DCM) improves the accuracy of Precise Point Positioning (PPP) by enabling Ambiguity Resolution (AR). Clock and bias corrections are typically estimated at 30-seconds rate to reduce the computation time. However, high rate PPP-AR applications, typically use 1 Hz tracking data, and ideally require 1-s clock corrections. The quality

PPP-AR reference satellite selection based on the observation quality factors

Measurement Science and Technology
Abstract Precise point positioning ambiguity resolution (PPP-AR) can effectively improve positioning accuracy and convergence time. In PPP-AR, the double-difference ambiguity between satellite pairs must be fixed. Therefore, it requires the selection of one satellite as a reference to conduct single-difference observations.
