EMMT Beacon
A penetrator-deployed navigation and communications beacon for lunar surface and asteroid operations.
Precision navigation
One-way ranging and timing references for spacecraft, rovers, and crews operating beyond GPS coverage.
Resilient S-band comms
Telemetry and command over a hardened 2.2 GHz S-band link with ≥14.6 dB margin across mission scenarios.
Standards-native
CCSDS Proximity-1 and LunaNet (LNIS v5) compatible for interoperable cislunar networks.
Built for deep space
Radiation-tolerant COTS avionics and a passive thermal design for the −183 to +120 °C lunar environment and high-g penetrator impact.
