The Nanoracks CubeSat Deployer (NRCSD) is a self-contained CubeSat deployer system that mechanically and electrically isolates CubeSats, and has been in operation since 2014. The NRCSD consists of anodized aluminum plates, base plate assembly, access panels, and deployer doors.
The NRCSD deployer doors are located on the forward end, the base plate assembly is located on the aft end, and access panels are provided on the top. The inside walls of the NRCSD are a smooth bore design to minimize and/or preclude hang-up or jamming of CubeSat appendages during deployment. Deployable systems shall be designed such that there is no intentional contact with the inside walls of the NRCSD.
Satellites are integrated into the Nanoracks CubeSat Deployer, and the deployer is then mounted directly to Panel 5 of the Cygnus spacecraft by the teams at Nanoracks and Northrop Grumman at NASA’s Wallops Flight Facility.
Upon launch, Cygnus generally remains at the International Space Station for about 30 days, which it is then released from the Space Station, and raised to an orbit of 450-500 km (50-100 km higher than ISS). Once this maneuver is complete, the satellites are deployed before the Cygnus moves into a re-entry burn.
