BSAT-4b

MEV-2 (Mission Extension Vehicle-2), built by Northrop Grumman, is a commercial satellite servicer that docks with ageing GEO satellites and assumes their orbital station-keeping, extending their operational life without taking them out of service. It docked with Intelsat 10-02 directly at the satellite's operational geostationary slot on 12 April 2021, without interrupting service to customers across Europe, the Middle East, Africa, and South America, and provided five years of life extension to IS-10-02.
