Key highlights

The 16U CubeSat Structure from EnduroSat is a flight-proven primary frame engineered for demanding, payload-heavy nanosatellite missions. Machined from Aluminum 6082 and weighing just 2.5 kg with screws and six mounted rings, this 16U structure pairs a lightweight build with a hard-anodized, pearl-finished surface for durability through integration, environmental testing, and launch. Full PC104 compliance and adherence to the CubeSat Standard mean off-the-shelf avionics stacks drop straight into the chassis without custom adaptation.

Integration teams benefit from a deliberately simple modular architecture: the CubeSat structure can be built up either vertically or horizontally, giving engineers flexible access to subsystems throughout assembly and rework. Deployment safety is covered by configurable kill switches, with an option for up to four. Backed by EnduroSat's heritage of more than 3,500 modules delivered to orbit, the 16U satellite structure is a dependable mechanical foundation for Earth observation, communications, and science payloads at the larger end of the CubeSat envelope.

Applications

Primary mechanical structure for 16U CubeSat missions
High-volume payload accommodation (Earth observation, communications, in-orbit demonstration)
Missions requiring PC104-compliant subsystem stacking
University and commercial nanosatellite programs scaling beyond 12U
Structural baseline for EnduroSat 16U platform-derived spacecraft
