Satellite Anomaly Recovery
In the event of a satellite anomaly, the ANT61 Beacon serves as a critical backup communication system, restoring functionality even when the primary systems fail. It independently collects and transmits real-time telemetry, allowing mission control to diagnose the issue, issue recovery commands, and regain control of the satellite. Additionally, the Beacon’s inter-satellite communication capabilities enable continuous two-way data exchange, ensuring connectivity with other satellites in the constellation for coordinated recovery efforts.
Continuous telemetry
The ANT61 Beacon provides continuous, real-time telemetry collection, offering operators vital insights into satellite health, including orbital parameters, radiation events, and system status. It operates autonomously or can be integrated into your existing network, sending data via inter-satellite links, ensuring a continuous flow of information even when the satellite is outside of coverage. This ensures that mission control can monitor the satellite’s performance from anywhere in orbit.

Firmware updates & remote maintenance
The ANT61 Beacon supports secure, remote firmware updates via its inter-satellite communications, enabling satellite operators to perform critical maintenance and restore functionality without direct access to the satellite. Whether a single satellite or a larger constellation, the Beacon ensures continuous communication between satellites and mission control, enabling remote diagnostics, firmware updates, and performance optimization across your entire fleet.
Backup communications
The ANT61 Beacon offers an independent, secure two-way communication system for satellite missions. In addition to providing backup communication for satellite anomaly recovery, the Beacon leverages its inter-satellite communication capabilities to enable constant, reliable satellite-satellite and satellite-ground connections. This ensures that even in the event of a satellite failure, the communication system remains operational, allowing mission control to issue commands, retrieve data, and coordinate recovery efforts in real-time.


Constellation support
Designed for satellite constellations, the ANT61 Beacon ensures seamless inter-satellite communication, providing a robust network for continuous telemetry exchange and system coordination. Whether for emergency recovery or routine health monitoring, the Beacon enables efficient communication between satellites, ensuring that data flows smoothly across the entire constellation. Its advanced inter-satellite link functionality supports real-time coordination, boosting the reliability and success of multi-satellite missions by maintaining connectivity even when individual satellites experience anomalies.
