Signal in Space Error and Ephemeris Validity Time Evaluation of Milena and Doresa Galileo Satellites [PDF]
In August 2016, Milena (E14) and Doresa (E18) satellites started to broadcast ephemeris in navigation message for testing purposes. If these satellites could be used, an improvement in the position accuracy would be achieved.

Accuracy Evaluation of Broadcast Ephemeris for BDS-2 and BDS-3 [PDF]
Abstract The BDS-3 system was completed in July 2020 and began to provide services to users around the world. The inspection of its operation, especially the detailed evaluation of the orbit, clock error, TGD and other indicators, plays an important role in the subsequent positioning.
