Enhancing BDS-3 PPP-AR with observable-specific signal biases

Measurement Science and Technology, 2023
Abstract In global navigation satellite system (GNSS) data processing, precise point positioning (PPP) with ambiguity resolution (PPP-AR) is a versatile technique that aims to achieve centimetre-level accuracy by resolving integer ambiguities in carrier phase observations.

Enhancing PPP-AR with satellite attitude data from ORBEX files

2023
Over the past decades, Precise Point Positioning (PPP) has become a well-established technique for determining the user's position with the signals of Global Navigation Satellite Systems (GNSS). PPP is characterized by applying precise satellite products (orbits, clocks, and biases) and accurately modeling a wide range of error sources to estimate the ...

Static and Pseudo-Kinematic PPP-AR Performance in Antarctic Region

2021
<p>Because of the inclined-orbit of GNSS constellations that are not cover the Polar Regions, the polar gaps occur between certain latitudes and therefore in these regions the satellite observations are limited around the zenith direction.

Comparison of GNSS PPP-AR packages for post-processing seafloor geodetic data.

2023
GNSS/A is a proven method to localize seafloor geodetic stations and, thus, to monitor seafloor tectonic phenomena. This approach combines GNSS positioning of a surface platform with acoustic ranging between this platform and acoustic beacons on the sea bottom, with the objective to localize the beacons in a global frame within a centimeter or so.

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.

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.

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

Positioning performance of GNSS-PPP and PPP-AR methods for determining the vertical displacements

Survey Review, 2021
This study investigates the accuracy of vertical displacements monitored by Global Navigation Satellite Systems (GNSS) precise point positioning (PPP) with float-ambiguity solution and with ambiguity resolution (PPP-AR). For this purpose, a simulation was designed. The static GNSS observations were collected at a test point during different observation
