A Message Transfer Service for Space Applications

2002, SpaceOps 2002 Conference

Abstract

Spacecraft applications that interact with on-board sensors, effectors, and major components have traditionally used private interfaces which are tightly bound to the interface details of the data links connecting these sub-systems. The latest spacecraft, which often include several powerful processors running real time operating systems, highspeed on-board networks, and intelligent peripherals, can support a more layered networked environment. Use of standard interfaces and networked elements is expected to yield reusable software and hardware components. Within CCSDS Panel 1K we have been developing such on-board interface standards. This paper will present a Message Transfer Service that defines a common API for use within a single spacecraft or among spacecraft flying in a constellation.
