Description
SpaceVNX+ [1] is a standard for small form factor equipment modules and units which is being designed specifically for space applications. Its modules are substantially smaller than a 3U Eurocard. SpaceVNX+ provides a standard platform for the implementation of the entire range of avionics applications on-board a spacecraft, from simple remote terminal units to high-performance payload data-handling units. SpaceVNX+ is intended to be complementary to larger form factor standards such as SpaceVPX [2] and ADHA [3]. This paper considers the critical design drivers for SpaceVNX+ that make it suitable for space applications, including thermal, size, modularity, connectivity, reliability and redundancy, and electrical constraints. The design of SpaceVNX+ is being driven by these considerations.
