About

The Remote Terminal Unit (RTU) is a highly reliable and fully redundant unit that serves as a critical bridge between the On-Board Computer (OBC) and various platform and payload electronic interfaces.

This versatile solution is designed with flexibility in mind, capable of handling a wide array of necessary functions such as standard I/O, Attitude and Orbit Control System (AOCS), and propulsion.

The RTU is part of Beyond Gravity’s traditional command and data handling product line, backed by over 40 years of experience in space electronics and a portfolio with more than 3,500 successful years in orbit.
