The XPOD Separation System was developed for nanosatellites and small microsatellites. The XPOD is an enclosed "jack-in-the-box" container for separating nanosatellites from virtually any launch vehicle. Various models are available, including models compatible with the CalPoly CubeSat standard. Once a deployment signal is received from the launch vehicle, a power supply inside the XPOD activates a release mechanism causing a door to open and the spacecraft to be ejected. The XPOD implements a single-failure fail-operational design, and is customizable for spacecraft up to 16kg with arbitrary dimensions. Also available are semi-enclosed (or "open concept") designs that accommodate fixed appendages. XPODs come in various standard models – the XPOD Single, XPOD Triple and XPOD GNB. Specifications are subject to change. Unit is delivered with functional testing only. Environmental acceptance is not performed unless negotiated with the customer.
