The EnduroSat 1U Cubesat structure is a CubeSat structure that provides a safe environment for the payload and sub-systems during all phases of the mission. The CubeSat structure is modular with 3 elements (top, bottom, and legs) that can be adapted as needed - for instance, a 1U Structure can be converted to a 1.5U structure by changing only the leg elements. This design approach allows the top and bottom elements to be used for different form factors. The system also come with kill switches and 2 separation springs already integrated.
