Summary
The HAWK-3B satellite, also known as Hawk 3B, was launched on June 30, 2021, from Launch Complex 40 at Cape Canaveral Air Force Station using a Falcon 9 launch vehicle. It is owned by HE360 and manufactured by UTIAS (University of Toronto Institute for Aerospace Studies). The satellite uses the Defiant bus configuration and has dimensions of 0.5 meters in length, 0.4 meters in diameter, and a span of 1 meter. Its dry mass is 30 kg with a launch mass of 31 kg. Equipped with solar cells and batteries for power, it is designed for RF spectrum monitoring, SIGINT (signals intelligence), and traffic monitoring missions. The satellite's lifetime is projected to be three years, and it employs FEES or water thrusters as its motor system.
