THE IMPACT OF ORBITAL AND CLOCK ERRORS ON POSITIONING FROM LEO CONSTELLATIONS AND PROPOSED ORBITAL SOLUTIONS [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023
Two approaches are discussed for the estimation and prediction of the orbits of low earth orbit (LEO) satellites that can be used for navigation. The first approach relays on using a ground monitoring network of stations.

Precise LEO orbit determination using regional PPP-B2b augmentation services

Measurement
Abstract The PPP-B2b service broadcasted by BDS-3 GEO satellites can provide centimeter to decimeter-level positioning accuracy in China and surrounding area. As a free satellite based-augmentation system, BDS PPP-B2b service also potentially benefits the low earth orbit (LEO) space users to improve the orbit determination accuracy.

A New Strategy for Improving Multi‐Frequency PPP‐RTK Ionospheric Correction Availability and User Performance in Low‐ and Middle‐Latitudes

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract High‐precision regional ionospheric correction products are essential for achieving accurate and fast‐convergence solutions in Precise Point Positioning Real‐Time Kinematic (PPP‐RTK). For users in low‐ and middle‐latitudes, PPP‐RTK server narrow‐lane (NL) ambiguity resolution (AR) typically requires more than 10 min, which largely affects the ...

A Novel Robust High‐Precision Ionospheric Delay Modeling for PPP‐RTK Using Crowdsourced Data

Space Weather, Volume 24, Issue 2, February 2026.
Abstract The performance of PPP‐RTK is critically dependent on the quality of ionospheric corrections derived from a reference network. While the proliferation of mass‐market Global Navigation Satellite System (GNSS) devices offers a promising crowdsourcing opportunity to densify or replace this infrastructure, it introduces the formidable challenge of
