Broadcast ephemerides for LEO augmentation satellites based on nonsingular elements
GPS Solutions, 2021Low earth orbit (LEO) satellite constellations have the potential to augment global navigation satellite system services. Among the ongoing tasks of LEO-based navigation, providing broadcast ephemerides that satisfy the accuracy requirement for positioning, navigation, and timing is one of the most critical prerequisites.

Accuracy Assessment of Broadcast Ephemerides for Quasi-Zenith Satellite System
Lecture Notes in Electrical Engineering, 2018In this paper, we presented a method for assessing the broadcast ephemerides accuracy of QZSS by comparing the measured broadcast ephemerides with precise orbit and clock products provided by MGEX. By using this method, we carried out assessment of broadcast ephemerides for QZS-1 satellite and also compared the results with that of GPS system during ...

Precise On-Board Navigation of LEO Satellites with GNSS Broadcast Ephemerides
Proceedings of the Satellite Division's International Technical Meeting, 2020The availability of orbit information with high precision and low latency is a key requirement for many Earthobservation missions, predominantly in the field of radio occultation. Traditionally, precise orbit determination solutions of low-Earth orbit (LEO) satellites are done offline on the ground after dwonloading GNSS measurements and required ...

Broadcast versus precise ephemerides: a multi-GNSS perspective
GPS Solutions, 2014A consistent analysis of signal-in-space ranging errors (SISREs) is presented for all current satellite navigation systems, considering both global average values and worst-user-location statistics. The analysis is based on 1 year of broadcast ephemeris messages of the Global Positioning System (GPS), GLONASS, Galileo, BeiDou and QZSS collected with a ...
