Analysis of Accuracy Positioning Performance of Low-Cost and Geodetic GNSS Using Precise and Broadcast Ephemeris

open access: diamondIOP Conference Series: Earth and Environment
The accuracy of GNSS positioning is largely determined by the type of ephemeris data applied. These include broadcast ephemeris, which is accessible in real time, and precise ephemeris, which is released after post-processing by institutions like the ...

A method for estimating the rotation errors of BDS broadcast ephemeris using global satellite laser ranging data

open access: hybridMeasurement science and technology
The BeiDou-3 Navigation Satellite System (BDS-3) generates navigation messages from a regional ground tracking network and inter-satellite links, relying on predicted station coordinates and Earth rotation parameters (ERPs).

IRNSS Orbit Determination and Broadcast Ephemeris Assessment [PDF]

open access: green, 2015
The Indian Regional Navigation Satellite System (IRNSS) is an emerging satellite based navigation system offering an independent positioning and timing service over India and neighboring regions. Based on satellite laser ranging data collected by selected stations of the International Laser Ranging Service (ILRS) precise orbits have been determined for

Galileo broadcast ephemeris and clock errors, and observed fault probabilities for ARAIM [PDF]

open access: gold, 2023
(English) The characterization of Clock and Ephemeris error of the Global Navigation Satellite Systems is a key element to validate the assumptions for the integrity analysis of GNSS Safety of Life (SoL) applications. Specifically, the performance metrics of SoL applications require the characterization of the nominal User Range Errors (UREs) as well ...

The Carrier Phase Time Transfer with Broadcast Ephemeris

open access: diamondJournal of Physics: Conference Series, 2019
Abstract Time transfer method PPP is restricted by the real-time and precision of IGS production, and the real-time application have not been widely implemented. Standard Point Positioning(SPP) can satisfy the application for the real-time customer, but the precision is low and is not satisfy the high precision customer.
