The impact of inter-satellite links on the ECOM model performance for BDS‑3 MEO satellites
Inter-satellite link (ISL) plays an essential role in current and future Global Navigation Satellite System (GNSS). A recent study, conducted by Wuhan University's GNSS Research Center and published in Satellite Navigation in May 2024, explored the significant effect of ISL data on the orbital characteristics of the BDS-3 MEO satellites.

Global geodetic parameters determination: Using satellite laser ranging observations to GNSS satellites
Satellite laser ranging (SLR) is one of the space geodetic techniques that uses lasers to measure the distance between ground stations and satellites with retroreflectors. This precise measurement provides critical data for determining the geocenter motion, terrestrial scale and Earth Rotation Parameters (ERP)—parameters fundamental to the International Terrestrial Reference Frame (ITRF).
