HawkEye 360 is an American geospatial analytics company headquartered in Herndon, Virginia. It is a commercial seller of radio frequency (RF) signal location data gathered by a satellite constellation. History In 2015, HawkEye 360 was started with the idea of using space and RF technology to generate usable data by advanced signal geolocation using small satellites. The main idea was to collect and geolocate RF signals for commercial use. In some time the company received initial seed financing from Allied Minds, a Boston-based venture capital firm, to expand the business. In 2016, HawkEye 360 began contracting the construction of their Pathfinder cluster of satellites with Deep Space Industries (DSI) and UTIAS Space Flight Laboratory (SFL). In November 2016, the company completed the initial Series A round led by Razor's Edge Ventures with major participation from defense industrial base leader, Raytheon. While waiting for the satellites to be built and launched, the company began exhibiting their technology through flight demonstrations and successfully received a patent for determining the location of RF transmitters. The company's advisory board includes former members of the National Geospatial-Intelligence Agency, retired Army and Air Force general officers, and former Intelligence Community leaders. In December 2018, HawkEye 360 launched the company's first set of small satellites, known as the Pathfinder cluster, into orbit as part of the Spaceflight's SSO-A SmallSat Express ride-share aboard a SpaceX Falcon9. The satellites, in both this first cluster and a later second cluster, were built by UTIAS Space Flight Laboratories (SFL) In April 2019, it released the first product - RFGeo, whose purpose is to identify and locate RF signals so customers can then view and analyze data. In October 2019, HawkEye 360 expanded the company's signal waveform library to include ultra-high frequency (UHF) band and L band frequencies, as well as an update to RFGeo. The company's signal expansion into the UHF band enables monitoring of push-to-talk radios, which have the potential to aid the discovery of cross-border smuggling operations and poaching. The update to RFGeo includes a process to extract vessels' MMSI identifiers embedded into their channel 70 broadcasts. Once this happens, a specific vessel can be matched to its broadcast, enabling by emitter tracking of objects. The RFGeo update also includes a catalog of previously collected RF Geo data, so customers can order and access archived data. In December 2019, the National Reconnaissance Office (NRO) granted HawkEye 360 a contract
