Ephemeris Error Correction for Tracking Non-Cooperative LEO Satellites with Pseudorange Measurements

IEEE Aerospace Conference
Correcting the ephemeris of a poorly known "non-cooperative" low Earth orbit (LEO) satellite, by utilizing pseudorange measurements by a ground-based receiver is considered.

Analysis of Satellite Ephemeris Error in Differential and Non-differential Navigation with LEO Satellites

IEEE Aerospace Conference
Low Earth orbit (LEO) satellite ephemeris error is analyzed for standalone (non-differential) and differential navigation. First, the range residual due to ephemeris error is derived for a standalone stationary receiver making range-type measurements to ...

A Double-Difference Doppler Shift-Based Positioning Framework With Ephemeris Error Correction of LEO Satellites

IEEE Systems Journal
In signals of opportunity (SOPs)-based positioning utilizing low Earth orbit (LEO) satellites, ephemeris data derived from two-line element files can introduce increasing error over time.
