The satellite deployer is designed to launch mini-satellites CubeSats from the station, using the JEM Remote Manipulator System, which works similar to a small robotic arm and was displayed in the Small Sat Deploy-Demo. CubeSats are approximately 4 inch cubes weighing no more than 2.7 pounds, producing its own power with solar panels and able to transmit signals.

The J-SSOD provides additional launch opportunities for these miniature satellites, while demonstrating new technologies for air, water and surface monitoring and also enables the crew to power up the satellites right before deployment which extends battery life and allows the crew to check functionality and make simple repairs.
