Space Flight Laboratory (SFL) completes on-orbit commissioning of HawkEye 360 Clusters 4 and 5 microsatellites

Space Flight Laboratory (SFL) has completed on-orbit commissioning of six radio frequency (RF) geolocation microsatellites developed for HawkEye 360 of Herndon, Va. Cluster 4 launched on April 1, 2022, and Cluster 5 launched on May 25, 2022, bringing the number of microsatellites built by SFL for HawkEye 360 and now in orbit to 15. The HawkEye 360 Constellation detects and geolocates RF signals for maritime situational awareness, emergency response, national security, and spectrum analysis applications. In addition to expanding HawkEye 360’s global revisit and collection capacity, Clusters 4 and 5 microsatellites include enhanced antenna functions for greater flexibility in detecting and geolocating signals across a wide range of frequencies, stated the Virginia company. www.utias-sfl.net
