26 June 2025 year Fr. 17:28 (UTC) From the starting ground on the Mahia Peninsula, UTC, using a launch vehicle «Electron» a launch was made 4 KA US mission «4x HawkEye 360».
«HawkEye 360» – it is a space network of civilian satellites, that uses radio frequency technology to monitor air, land and sea transportation, assistance in emergency situations and execution of civilian missions. Constellation of small satellites (under the name Hawk) will collect information about certain radio signals worldwide, to provide high-precision radio frequency mapping and analytics from low Earth orbit. 3 satellites will enter the cluster 12 HawkEye 360 and will work in polar orbit, and the fourth is Kestrel-0A – Experimental satellite, designed to evaluate new opportunities and future technological improvements.
The HawkEye group of commercial satellites 360 provides a whole new level of data, which has never been available before – precise mapping of radio frequency radiation. This unique ability to identify and geolocate radio frequency sources from space reveals previously unseen knowledge of activities around the world.
The constellation will consist of 4 clusters with three satellites each. The low Earth orbit and wide field of view of the satellites provide wide coverage. Satellites are capable of being tuned to a range of frequencies from 144 MHz up to 15 GHz (approximately VHF to Ku-band). HawkEye 360 quickly expands the group, to increase repeat visits and increase throughput, starting with the highly developed Cluster satellites 2.
HawkEye 360 uses its own algorithms for processing radio frequency data, created by satellites. The resulting analysis gives an idea of the spectral environment and the location of the emitters. HawkEye 360 represents the computed location of the object with probability 95%. Current signals, which can be tracked include marine radios, Push-to-Talk radio stations, L-band mobile satellite devices, X-band and S-band marine radar systems, AIS beacons, emergency beacons, etc. The signal library will grow over time.
