Spacecraft Monitoring and Control for LuaJIT

Overview

This is an attempt at developping a set of tools for telemetry and telecommand processing in LuaJIT, centered around the CCSDS Mission Operations set of standards, namely XTCE and the MO Stack (MAL, COM, M&C services).

Also there are no tests.

Also it's awesome: the decommutation library can process 50Mb of raw telemetry in less than 15 seconds on my MacBook Air.

Content

This repo consists of decommutation library for LuaJIT in libdecom.lua (with various included dependencies) and a set of scripts:

• decom: A command line interface to the decom library. Takes a file and an optional decommutation model and outputs the results of the decommutation in the form of serialized JSON objects in a file.
• generator: Generates a Lua decommutation model from an XTCE file.
• concat: Makes a big file by concatenating multiple copies of a small file
• acqd: A telemetry acquisition daemon in Lua. Reads packets from a file and send them one by one over a ZeroMQ socket
• acqctl: command line interface to the acquisition deamon. Can only send a "go" command for now.
• decomd: A telemetry decommutation daemon in Lua. Gets packets from an acquisition daemon and publish parameter values in JSON or MessagePack over a ZeroMQ socket.
• decomd: A storage daemon for packets and parameters in Lua. Subscribe to parameter values from decomd and stores them in a file.

How stable is it?

It's all very much a work in progress. i will break code and change APIs without warning. Do not use this software for anything serious (yet). I mean it. You've been warned.

Requirements

The decommutation library requires LuaJIT 2.1+ as it relies on 64 bits bitop operations.

Documentation

There isn't any. But you can call the scripts with '--help' to get the basic options. For the rest, just look at the code.
