Communication

1 Fast alert downlink

Once transient astronautic objects are caught sight by WXT in orbit, scientific alert message for event report will be downlink to ground stations as soon as possible via the short-message-broadcast service of Beidou navigation system or VHF network service.

 

2.ToO uplink

EP satellite is able to maneuver in-orbit to set the FXT pointing to transient astronautic objects found and located by other ground-based facilities, via uplinked telecommands from ground stations. The near-real-time telecommands uplinked is realized through the short-message-broadcast service provided by Beidou navigation system, with the telemetry telecommand system as an alternative backup.
