The regional [[Mission control center|operations centers]] for the satellites were located in [[Silver Spring, Maryland]] for AfriStar and [[Melbourne, Australia]] for AsiaStar.<ref>{{cite web|title=Form 10-K Worldspace, Inc.|url=https://www.sec.gov/Archives/edgar/data/1315054/000119312508071173/d10k.htm|date=December 31, 2007|website=sec.gov

Telemetry, command and ranging (TCR) [[ground station]]s consisted of an [[X band|X-Band]] uplink command and control system and an [[L band|L-Band]] telemetry monitoring system. A backup mode was also provided using an [[S band|S-Band]] link from [[Bangalore]], [[India]]. Each satellite had two TCR stations with sufficient geographic distance between them so that if natural disasters or any unforeseen events were to make one inoperable, a back-up station would be available. The TCR stations for AfriStar were located in [[Bangalore, India]] and [[Port Louis, Mauritius]], and the ones for AsiaStar in Melbourne, Australia and Port Louis, Mauritius.

In addition to the TCR stations, a communications system monitoring station (CSM) was associated with each satellite to monitor continuously the quality of the downlink services. The CSM facilities were located in [[Libreville, Gabon]] and [[Johannesburg, South Africa]] for AfriStar and Melbourne, Australia for AsiaStar.<ref name="sec.gov"/>
