GROUND SEGMENT

XTAR-EUR and XTAR-LANT are controlled and monitored through an extensive, independent and secure Ground Control System (GCS) operated at MAC I configuration.

The XTAR fleet and payload control systems leverage a diversity of ground control connectivity, including facilities on the outskirts of Toronto, Canada; Mt Jackson, Virginia; Madrid, Spain and the Canary Islands, Spain. Geographically separated, these multiple GCS sites provide an exceptional level of security and operational redundancy to ensure continuous operations. Through operational agreements between XTAR and its HISDESAT partner, the two companies have agreed to provide a third level of backup by sharing resources during emergency operations.

The XTAR satellites operate with NSA-approved encrypted command and control links which are capable of simultaneous command and ranging. Ranging accuracy on both spacecraft maintains a synchronous, circular, equatorial orbit station to +/- 0.05° in orbit inclination and +/- 0.05° in longitude at the equatorial crossing.

The attitude determination and control system maintains the spacecraft attitude to within 0.02° in roll, pitch, and yaw. The satellites are designed to function optimally during all operational phases.
