About
The Canisterized Satellite Dispenser (CSD) is Planetary Systems Corporation’s reliable, testable, and cost-effective deployment mechanism for small secondary and tertiary satellite payloads. Unlike open rail-style deployers, the CSD fully encapsulates the payload during launch, providing privacy and mission assurance for both the primary payload and the launch vehicle. It is easy to load, integrate, and operate, requires no consumables, and allows the payload to be stowed, ejected, and re-stowed in seconds during integration and testing. The CSD offers the largest internal volume in its class, leaving more room for solar panels and other deployables, and its array of mount points allows mounting to any face, reducing interface structure mass and enabling dense payload packaging on the launch vehicle. It is available in 3U, 6U, and 12U sizes with roughly 2 kg-per-U mass capability, and has been used to deploy CubeSats including the POPACS mission.
