# Satellite Ground Station
|
|
The Spacecruft Satellite Ground station is a libre design for tracking
|
|
satellites.
|
|
|
|
It is intended for use with the Libre Space Foundation's SatNOGS network,
|
|
and is based on their freely available files.
|
|
|
|
This design will work for daily, but not continuous operation.
|
|
This design did ~8,500 observations in ~3 months for SatNOGS,
|
|
then the Yaesu Az rotator failed, due to over-running the system.
|
|
|
|
A more robust system, designed for 24/7/365 continuous operation,
|
|
see the Mighty Satellite Ground Station (MSGS) repository:

# Overview
|
|
Designed for artificial satellite tracking.
|
|
|
|
* Libre.
|
|
* 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.
|
|
* 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 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.

# TODO
|
|
|
|
* Rotator cable assemblies requires to cut off 6-pin connectors and
|
|
strip leads. Crimping O connectors is better, but ideally is an easy plug.
|
|
|
|
* Yaesu GS-232B in SatNOGS client uses an old Debian Buster hamlib package,
|
|
which requires a patch or it will stutter.
|
|
|
|
* See "Evaluate or Find" tab in BoM spreadsheet.
