A 16-parameter GEO Broadcast Ephemeris [PDF]
Journal of Geodesy and Geoinformation Science, 2018 Currently, the broadcast ephemerides used in GEOs are same as those of the MEOs and IGSOs in the BeiDou navigation constellation. However, a trade-off strategy, i.e.

A Real-Time Detection Method for BDS Signal in Space Anomalies [PDF]
Sensors, 2019 Signal In Space (SIS) anomalies in satellite navigation systems can degrade satellite-based navigation and positioning performance. The occurrence of SIS anomalies from the BeiDou navigation satellite System (BDS) may be more frequent than for the Global

Distribution of clock correction and ephemeris parameters in broadcast navigation messages [PDF]
GPS Solutions, 2021 AbstractThe distribution of clock correction and ephemeris (CCE) parameters in navigation messages broadcast by operational satellite vehicles (SVs) of the Global Navigation Satellite System (GNSS) is studied. For this purpose, two evaluation metrics are proposed, namely atypical navigation message structures and time to complete CCE sets (TTCS).

Galileo broadcast ephemeris and clock errors, and observed fault probabilities for ARAIM [PDF]
, 2023 (English) The characterization of Clock and Ephemeris error of the Global Navigation Satellite Systems is a key element to validate the assumptions for the integrity analysis of GNSS Safety of Life (SoL) applications. Specifically, the performance metrics of SoL applications require the characterization of the nominal User Range Errors (UREs) as well ...
