Phase Center Corrections for BDS IGSO and MEO Satellites in IGb14 and IGSR3 Frame
Ziyang Qu,Jing Guo,Qile Zhao +2 more
TL;DR: In this paper, the phase center variations (PCV) and phase center offset (PCO) values for GNSS medium earth orbit (MEO) and inclined geostationary orbit (IGSO) satellites are estimated to be consistent with GPS/GLONASS antenna offsets.

SLR validation and evaluation on BDS precise orbits from 2013 to 2018
TL;DR: In this article, the authors used satellite laser ranging (SLR) data over a 5-year time series to validate and evaluate the accuracy of the BeiDou Navigation System (BDS) using microwave-based precise orbits.

Simulation of Inter-Satellite Link schemes for use in precise orbit determination and clock estimation
Tomasz Kur,Maciej Kalarus +1 more
TL;DR: Establishing ISLs more often, with sampling interval on the level of 30 s or less, seems to be the most promising in improving the orbit determination, as well as reducing orbit errors in reference to GNSS-only solution from 30% to 40%.
Journal ArticleDOI
Augment BeiDou real-time precise point positioning using ECMWF data
TL;DR: In this article, the authors applied the tropospheric delay information derived from the European Centre of Medium-Range Weather Forecasts (ECMWF) analysis and prediction data, into the simulated real-time BeiDou-only and BeiDou/GPS PPP to augment the solutions.

Demonstrating developments in high-fidelity analytical radiation force modelling methods for spacecraft with a new model for GPS IIR/IIR-M
Santosh Bhattarai,Marek Ziebart,S. Allgeier,Stuart Grey,T. Springer,David A Harrison,Zhenhong Li +6 more
TL;DR: In this paper, the performance of various orbit model parameters in a full-orbit estimation process that uses tracking data from 100 stations is examined, and the results show that using a grid-based model for the orbit determination process reduces mean 3D orbit overlap values by 9% and the noise about the mean orbit overlap value by 4%, when comparing against orbits estimated using a simpler box-wing model of the spacecraft.
