Node 1: A new high performance 5G communications system for nanosatellites

Abstract:

In this paper, Node 1 system is introduced, as the Open Space Network foundation that will take the first step in building the base infrastructure for the next space revolution. Node 1 is the first space supercomputer and an advanced SDR, with the fastest data speeds plus the most advanced sensors; it will allow innovators, to connect and share resources via de SOS (Space Operating System) with Distributed Computing systems, Networks or Collaborative Systems and enhance their spacecraft's through CubeSat standard connectivity. Node 1 is a two-board system: the 256 cores Massively Parallel Processor Array (MPPA) running at 600 MHz named as the Mission Control Computer (MCC); and the Space AI Communications Card (SAI-CC), that is the most powerful SDR communications system available for commercial space, both fully compatible with CubeSat standard. A discussion over the most important functionalities of the MCC is introduced, also a detailed revision of the SAI-CC will be presented. The description of the Space Operating System (SOS) as an innovative proposal to have a collaborative open environment in space will be the last part of this work.
