The popular 3U CubeSat platform contains the core flight-proven subsystems and offers advanced capabilities in a mid-sized package. With precise Attitude Determination and Control, high-end communications architecture, increased electrical power and a robust Command & Data Handling System – the 3-Unit is the CubeSat platform of choice for more complex missions such as maritime safety & vessel tracking (AIS), air traffic monitoring (ADS-B), Signals Intelligence (SIGINT), Internet-of-Things services (IoT), Earth Observation (EO) and Science Experiments.
