The ThothX Earthfence Deep Space Radar (DSR) is a fully digital, pulse compression radar system, able to track meter scale objects in geostationary (GEO) orbits up to 50,000 km and in beyond in XGEO. Earthfence GEO detects and ranges known geostationary assets and unknown targets such as orbital debris. Ranging data is accurate to better than 25 m, sufficient for use in spacecraft navigation, surveillance of space, space traffic management and collision avoidance.

Earthfence GEO is the world's first commercial DSR. ThothX is bringing this unique capability to Space Domain Awareness (SDA) markets. Space is increasingly congested, with new spacecraft being launched all the time. Telecommunications satellites cost billions of dollars and are now essential to our way of life. It’s vital to know their location as well as that of debris and other spacecraft that might pose a threat.

The ThothX Earthfence GEO radar tracks targets continuously over periods of hours or days in order to develop high resolution orbits and range rates. Target detection is validated by means of radar cross section, spacecraft dimension and antenna configuration.

ThothX provides Earthfence GEO radar data from our sensor provider at the Algonquin Radio Observatory in Canada. We are expanding worldwide to create a global GEO radar ranging capability for SDA.
