Product Details

(1) Overview

OBC (On-Board Computer) serves as a hardware platform for running satellite operation flight software, controls the satellite and collects and stores the status of the bus and payload and sends it to the ground station.

At AP Satellite Inc., we developed the OBC by designing the module by its features and building the standardized interface. This allowed us to reduce development time and cost as well as development risk so we can supply a satellite OBC that can be used for a wide range of international space projects including low-earth satellite, geostationary satellite, exploration satellite and lander.
