# Mighty Satellite Ground Station

***DRAFT***

The Mighty Satellite Ground Station (MSGS) is a libre,
heavy duty, extra features design for tracking satellites.

MSGS is intended for use with the Libre Space Foundation's SatNOGS network,
and is based on their freely available files.

MSGS is a more robust version of the earlier
Satellite Ground Station, documents available here:

# Overview
Designed for artificial satellite tracking.

* Libre.
* Heavy duty.
* Completely documented design listing all parts and sources
  from Antennas to Zipties.
* All commodity-off-the-shelf (COTS) parts generally available in
  North American markets.
* Requires no special tools or skills to assemble.
  Just needs two adjustable wrenches, a screwdriver, and wire cutters.
* VHF and UHF antennas on crossboom.
* Software defined radio (SDR).
* Az/El rotator optimized for satellite tracking.
* 24/7/365 outdoor operation.
* Relatively low cost, but parts selected for quick deployment not price
  (e.g. no Arduino hacking, no soldering, no drilling, etc.
   which could lower price).
* Indoor computer and controllers.
* 110V AC power (e.g. not a solar system).
* Quick and easy mast deployment.
* Non-permanent mount, which can be easily moved.
* All parts shipping via courier (UPS, FedEx), no freight required.
* Easily serviced, upgraded, modified.


# Bill of Materials
The core document is the Mighty Satellite Ground Station Bill of Materials (BoM).
It is a spreadsheet in Libre Office format.

# SatNOGS
*A global network of satellite ground stations, designed as an open source
participatory project.*

* SatNOGS Website --- https://satnogs.org/
* SatNOGS Network --- https://network.satnogs.org/

The base design comes from the Libre Space Foundation.
The present design adds review of other designs in the SatNOGS network
and feedback from the #SatNOGS Matrix channel.
