Notes on setting up galmon.eu ground stations.

# Galmon
|
||||
Galmon is a system to monitor GNSS.
|
||||
Ground stations on Earth use `galmon` software to collect data
|
||||
from each GNSS satellite.

# Ground Stations
|
||||
There are two main GNSS chipsets that the `galmon` software support.
|
||||
UBX and Septentrio.
|
||||
The former is more widely used and easier to set up.
|
||||
This doc covers just the latter for now.
|
||||
|
||||
## Septentrio
|
||||
The Septentrio device is available as apparently very high quality
|
||||
standalone (unobtanium?) hardware that can plug directly into ethernet,
|
||||
amongst other configurations. Septentrio also resells their chips to
|
||||
third party integrators that make their own more readily available
|
||||
boards, such as the one used in the following setup.

||||
