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.
