The HEX20 12U CubeSat unit provides 8-12 units of payload space, requisite power, high-speed data link, and a comprehensive attitude and trajectory control suite. HEX20 12U platform is optimized for operations that require multiple large payloads, high power requirements and high LEO orbits for high accuracy earth observation, high throughput communications, deep space missions and defense missions Using advanced satellite subsystems, we have eliminated the single point of failures and ensured reliability and redundancy.
