A Simplified BDS Broadcast Ephemeris and State Space Representative (SSR) Matching Method for BDS-Only Real-Time Precise Point Positioning (PPP) [PDF]
IEEE Access, 2019 As opposed to the GPS real-time precise point positioning (PPP) with sophisticated orbit/clock recovery method, BDS real-time PPP applications were limited by the fact that no internationally recognized BDS issue of data (IOD) calculation and matching ...

A Study of GPS Precise Ephemeris Interpolation for Maritime Precise Positioning Applications
Journal of Korean navigation and port research, 2009 Currently many vessels determine an overhead obstruction by a rule of thumb based on their draft for maritime navigation. Therefore they doesn`t have a good overhead obstruction clearance because vertical position of vessels varies on time by tidal. As a result, it is occurred maritime accidents that the mainmast of vessels is bumped against overhead ...

Broadcast Ephemeris with Centimetric Accuracy: Test Results for GPS, Galileo, Beidou and Glonass
Remote Sensing, 2021 Here we test the capability of the Broadcast Ephemeris Message, in both its GPS-like (Keplerian ellipse with secular and periodic perturbations) and Glonass-like (numerical integration of a 9D state vector) formats, to reproduce a corresponding precise ...
