Cubesat platforms

Modular platform for turn-key solutions

Flight proven, cost-effective platforms

ISIS 3U cubesat platform

The ISIS CubeSat bus is a flight proven, cost-effective platform with a reduced time-to orbit platform that meets the performance required for a wide range of nanosatellite based applications; from satellite-based AIS ship tracking and Earth observation to astronomy and life sciences. The ISIS platform is delivered pre-integrated. As every mission is one-of-a-kind and therefore, we have focused on a CubeSat bus design that enables the right balance between flexibility, compatibility, and reliability, allowing your team to focus in the mission and payload reducing your total time-to-orbit.
