The software will then upload the latest satellite transponder data from the two SatcoDX servers (one is the main server and the other is a backup in case the main server is down). SatcoDX’s World of Satellites now has the latest satellite information. You can perform an update as many times as you wish to keep the software up-to-date with the latest data. The SatcoDX satellite list is constantly being updated since there are always changes occurring (new channels start operating, others stop transmitting or the parameters for existing channels change).
