In-Orbit Demonstration (IOD)

In-Orbit Demonstration (IOD)

The In-Orbit Demonstration (IOD) Programme offers partners a fast-track, low-cost opportunity to test their service or technology on a CubeSat mission launched into low Earth orbit.

IOD helps accelerate to ‘proof of concept’ stage by providing an affordable in-orbit testbed and a range of operational and business support services to exploit the commercial potential of the mission.

Our Missions

Missions in progress


IOD-1 GEMS was launched to the International Space Station in April 2019. This mission is being carried out with Orbital Micro Systems who have expanded their operations from the United States due to the capabilities the UK has to offer. The service demonstrated by this satellite will look to improve weather observing and forecasting.

IOD-5 TARS was launched on 3 September 2020. This mission is in partnership with Kepler Communications as a final prototype to their GEN1 constellation for IoT services. The mission follows on from the successful launches of their first two demonstrators, KIPP and CASE.

IOD-3 AMBER is currently going through the design phases and will be manufactured in the next few months. The mission will adapt Horizon Technologies’ existing FlyingFish™ signals intelligence (SIGINT) system for a 6U CubeSat platform.
