Rad-Tolerant Low Power Avionics for Deep Space Small Spacecraft

Completed Technology Project

Project Introduction

This effort is focused on the development a low power, low mass and radiation tolerant integrated avionics platform for small spacecraft applications including: orbiters, landers, and deployables/daughtercraft. This avionics will demonstrate multiple subsystems in a spacecraft integrated into a single assembly sharing an embedded multicore processor which is 8x faster then the current flight processor. The assembly will integrate Command and Data Handling (CDH), telecom, Guidence Navigation & Control (GNC), Motor Control, and Power. This is a fully rad-hard platform.

 Small Spacecraft Avionics (SSA) is an avionics platform designed to fill the gap between cubesats and large flight avionics.  The avionics is designed to operate in dual or single string configuration.  SSA integrates CDH, GNC, motor control, and telecom into a single assembly.  SSA supports  SpaceWire interconnects to the payloads as weill as PMBus interface to the power subsystem.  SSA provides an integrated avionics solution in a  small form factor to allow missions to perform deep-space flagship-quality science in a small spacecraft and reduce cost and schedule.  SSA is designed to enable low-cost small spacecraft by providing a commidity avionics solution which can support a variety of missions out of the box.
