Onboard control system for moon artificial satellite

The authors present onboard control system for small spacecraft, working in mobile connection system in near-moon orbits. They consider requirement specifics, which making to onboard control systems for work in orbit of Moon. They provide analysis of current onboard control system architecture, new architecture choice, part of new system choice. Advantages of using SpaceWire prospective network technology are considered. Hardware realization steps of onboard control system are considered. Onboard control system new construction implementation, which allows to improve system energy and mass characteristics is examined.
