GOMX-5 is a low Earth orbit technology demonstration satellite under development by the European Space Agency (ESA) and the Danish company GomSpace. The mission is designed to demonstrate a new 8U CubeSat platform for GomSpace, as well as an innovative maritime domain awareness payload detecting signals across UHF to X-band for maritime surveillance. ^{[1] [2] [3] [4]} The satellite also carries a radiation detector developed by Czech Technical University with ESA support. ^{[5] [6]} The satellite is equipped with an electric propulsion system, developed by the French company ThrustMe, for orbit raising and end-of-life disposal in compliance with ESA's space debris mitigation policy. ^{[7] [8]} GOMX-5 was launched in October 2026 on Falcon 9's mission Transporter-18. ^{[2] [3] [4] [9] [10] [11]}
