Precise point positioning study to use different IGS precise ephemeris

2011 IEEE International Conference on Computer Science and Automation Engineering, 2011
The fundamental principle and considered fundamental factors of GPS precise point positioning are discussed, the experimental research show that the error of GPS precise point positioning is greater to use broadcast ephemeris, and broadcast ephemeris can obtain only the accuracy of meter level, the positioning error of Z direction is greater than X ...

Fugro Marinestar Precise Point Positioning status update

Hydrographische Nachrichten, 2023
Fugro Marinestar Precise Point Positioning (PPP) utilises a global network of 111 reference stations to provide centimetre-level positioning in real-time to maritime users. The system estimates precise orbit, clock and satellite phase bias corrections for GPS, Galileo, BeiDou and GLONASS satellites. Factors such as ionospheric activity, scintillations,

Precise Point Positioning for Next-Generation GNSS

2020 European Navigation Conference (ENC), 2020
Precise Point Positioning (PPP) provides accurate absolute position information without the direct need of measurements from a reference station at the user. The current challenge of GPS L1/L2-based PPP is its long convergence time of more than 20 minutes being caused by the need to estimate atmospheric parameters, and the relatively large code noise ...

Performance Evaluation of Galileo Precise Point Positioning

2019
Galileo Satellite Navigation System has been put into trial operation at the end of 2016. Whether Galileo Satellite Navigation System can be used independently for navigation and positioning needs to be analyzed and evaluated because it is not yet in full constellation, especially the performance of Galileo Precision Point Positioning is worth studying.

Multifrequency algorithms for precise point positioning: MAP3

GPS Solutions, 2013
We present the new MAP3 algorithms to perform static precise point positioning (PPP) from multifrequency and multisystem GNSS observations. MAP3 represents a two-step strategy in which the least squares theory is applied twice to estimate smoothed pseudo-distances, initial phase ambiguities, and slant ionospheric delay first, and the absolute receiver ...

Performance of Real-Time Precise Point Positioning

Marine Geodesy, 2013
The IGS Real-time Pilot Project (IGS-RTPP) provides real-time precise orbits and clocks, which support real-time positioning for single stations over large areas using the Precise Point Positioning (PPP) technique. This paper investigates the impact of real-time orbits, network configuration, and analysis strategies on real-time PPP implementation and ...

Gps precise point positioning with kinematic data

Pollack Periodica, 2011
Nowadays most of the users needing geodetic accuracy use the Global Positioning System (GPS) with static measurements or with RTK (Real Time Kinematic) measurements. Few seconds are available to measure a detail point, therefore only the RTK method can satisfy the expectations.

Single-Point GPS Positioning Accuracy Using Precise GPS Data

Australian Surveyor, 1997
Abstract Over the last few years, increased attention has been given to the use of precise GPS satellite ephemerides and clock corrections together with calibrated ionospheric models as an efficient and economical alternative to conventional differential GPS (DGPS).

Real-Time Precise Point Positioning Using BeiDou

2015
Satellite positioning is evolving rapidly, with the deployment of Galileo and BeiDou systems, in addition to the modernisation programmes for GPS and GLONASS. At the time of writing, the BeiDou constellation consists of 5 Geostationary Orbit (GEO), 5 Geosynchronous Orbit (IGSO) and 4 Medium-Earth Orbit (MEO) satellites.
