The ISIS 2-Unit Long Stack CubeSat structure is developed as a generic, modular satellite structure based upon the CubeSat standard. The design created by ISIS allows for a ~1,5U stack, giving CubeSat developers maximum flexibility in their design process.
The stack of PCBs and other flight modules can be build up first in the secondary structure and integrated with the deployer interface guide rails at the end of the process, ensuring accessibility of the flight avionics. In addition, the use of these profiles guide rails and detachable shear panels allows for access to all parts of the spacecraft avionics, even after final integration by removing one or more of the shear panels. The modular chassis allows for one ~1,5-Unit stack of PCBs or other module and a ~0,5U payload to be mounted inside the chassis.
