The GomSpace GOMX-5 mission represents a significant milestone in advancing CubeSat technology, combining flight qualification of GomSpace’s new standardized satellite platform with demonstration of innovative payload capabilities for Maritime Domain Awareness (MDA). Developed to address growing market needs for cost-effective, reliable, and scalable small satellite solutions, the mission, targeted for launch in H1 2026, will validate a new 8U CubeSat configuration in orbit, utilizing GomSpace’s experience and technology portfolio to streamline spacecraft design while guaranteeing high performance.
The GOMX-5 platform introduces a modular architecture optimized for scalability and rapid deployment, offering a reference design adaptable for diverse missions. This mission will validate the modular design’s adaptability for diverse applications, including its integration of advanced subsystems such as deployable tracking solar panels, high-power management systems, and advanced communication links capable of S-band, X-band, and experimental Ka-band downlink capabilities. A modular payload computer, the GomSpace NanoMind HP Mk3, will facilitate seamless integration of mission payloads while maintaining a standardized core design for platform subsystems. This modular approach supports the development of dependable, off-the-shelf CubeSat configurations by lowering mission risk and improving the ability to reuse proven designs.
The primary focus of the GOMX-5 mission is to validate an advanced Maritime Domain Awareness payload. Designed to monitor maritime communication frequencies, the payload can detect and analyze signals across UHF, L-band, S-band, and X-band ranges. Critical applications like tracking ships, keeping an eye on illegal behavior, and assisting with geolocation services for marine surveillance are made possible by this capacity. GomSpace’s value offer to clients looking for tested, complete solutions for maritime monitoring applications will be strengthened by the demonstration of this payload in orbit.
Additionally, the GOMX-5 mission will serve as a testbed for ongoing software validation and on-orbit learning. GomSpace will employ its System Integration Lab (SI-LAB), a facility designed for comprehensive system testing, alongside its LabSat platform, a ground-based replica of the GOMX-5 satellite. This dual setup allows for rigorous pre-deployment validation of software updates, firmware releases, and operational procedures. By leveraging these tools, GomSpace will ensure that updates are tested in a controlled environment before being deployed in orbit. This process minimizes risks associated with live testing and demonstrates the rapid deployment and validation of new software features. GOMX-5, therefore, establishes itself as an orbital laboratory, paving the way for continuous improvements and innovations in satellite technology.
Furthermore, the mission will validate compliance with ESA’s Zero Debris Policy by showcasing collision avoidance and safe deorbiting strategies. Equipped with an onboard propulsion system, the GOMX-5 spacecraft will conduct orbit adjustment maneuvers designed to ensure deorbit within five years, contributing to global sustainability efforts in space operations. By achieving these objectives, GOMX-5 sets a benchmark for responsible and sustainable satellite missions.
Through GOMX-5, GomSpace underscores its dedication to advancing CubeSat reliability, innovation, and sustainability. The mission not only strengthens the company’s position in the small satellite market but also provides valuable flight heritage for emerging technologies. This demonstration mission paves the way for future constellations and operational deployments, reinforcing GomSpace’s role as a leader in next-generation satellite systems.
