ComSpOC signed a data provider agreement last week with Thoth Technology, operators of the Algonquin Radio Observatory (ARO), to formalize efforts to advance the state of radar tracking of Geostationary (GEO) satellites and debris. This endeavor will upgrade a 46-meter radio astronomy antenna to include radar for surveying debris at geostationary altitude, and expand the space catalog to include objects that until now, have not been tracked.

This site is a welcome addition to ComSpOC’s growing ground-based sensor network of over 50 optical sensors, long and short baseline RF interferometric sensor networks on two continents, and two phased array radars. ComSpOC integrates this data to develop high fidelity space situational awareness (SSA) products that track and characterize resident space objects with the results distributed via its Spacebook subscription. Space debris is a growing threat and through this agreement, ComSpOC and Thoth aim to map the most complete picture of the GEO belt to help ensure safe operations.

Paul Graziani, AGI’s chief executive officer and ComSpOC founder, has high hopes for the path forward: “We are very excited to work with Thoth on this venture. Having a 46m dish equipped with radar to survey the Geo-Belt on a daily basis will significantly increase the size and quality of our GEO belt catalog, which in turn will enhance ComSpOC’s ability to provide accurate, actionable, and timely collision assessment and warnings.”

About ComSpOC

In 2014, AGI established a Commercial Space Operations Center, which was subsequently incorporated as ComSpOC Corp. ComSpOC Corp. is an AGI affiliate. ComSpOC fuses satellite-tracking measurements from a geographically diverse set of optical, radio frequency (RF), radar and space-based sensors to generate HiDEph and other SSA data products. These results are available via subscription to the next-generation space catalog, SpaceBook™, which currently includes over 8,000 space objects, and 100% of all GEO objects.
