Existing communication systems for LEO spacecraft are limited to the ground station overpass period (approximately 10 minutes per orbit). To use this extremely limited but vital communications link, satellite operators must invest in expensive ground segment infrastructure or lease dedicated facilities. The operational features of this arrangement dictate the use of on-board data storage and often lead to out-of-date data.
Our SB-SAT terminal revolutionizes the way satellite operators access LEO spacecraft by enabling continuous, near real-time communications. The spaceborne terminals relay signals to the Inmarsat IV network in geostationary orbit and then through the Inmarsat ground stations to the user or operator, making full use of Inmarsat’s mobile broadband system and proven infrastructure. The user application layer is fully accessible from anywhere on the globe through a secure internet connection. Guaranteed throughput is available at application-specific rates.
Typical applications are instant access to telemetry, tracking and command and payload data, rapid access to time-critical data such as space weather, radically improved anomaly investigation, and launch vehicle TT&C for increased launch geometry options among others.
