Hi!
|
|
|
|
Many thanks for joining the galmon.eu project as an observer and station operator!
|
|
|
|
Here are some ground rules to follow once you have locally tested your galmon station:
|
|
|
|
* Please ask bert@hubertnet.nl or [ahu on
|
|
IRC](https://webchat.oftc.net/?channels=galileo) or
|
|
[@PowerDNS_Bert](https://twitter.com/PowerDNS_Bert) for a station ID and receiver
|
|
hostname.
|
|
* Please do not randomly pick a station ID!! Project data quality and integrity
|
|
depends on your cooperation.
|
|
* The rule is: one station ID per receiver. Do not under any circumstances
|
|
use the same ID on multiple receivers, even if you think it should be
|
|
fine. We have 2^64 IDs available, just ask for more IDs.
|
|
* Even if you think it should be fine to reuse the same ID, for example
|
|
because your observer page on galmon.eu will look nicer, DO NOT DO IT!
|
|
It messes up our algorithms which track the clock of your receiver.
|
|
* Please set the --owner and --remark fields - they help with administration.
|
|
These fields will show up on https://galmon.eu/observers.html
|
|
* Ublox8 based receivers support (GPS AND Galileo) + (BeiDou OR GLONASS). They can't
|
|
process all four systems at the same time. GPS and Galileo share a slot. BeiDou or GLONASS
|
|
share a second slot. See
|
|
[here](https://www.geospatialworld.net/blogs/gnss-frequency-bands-for-constellations/)
|
|
for some more information.
|
|
* If you want to know if you should add BeiDou or GLONASS, you can either use your own
|
|
preference or ask us what we are missing in your region.
|
|
|
|
Downtime
|
|
--------
|
|
The project is grateful for every bit you can provide. Don't feel bad about
|
|
downtime either because your family needs the power plug for Christmas
|
|
decorations (this happened) or for whatever reason.
|
|
|
|
A good way to increase uptime is to use the Systemd file to ensure automatic
|
|
startup on reboots. Some stations with bad power, bad hardware or bad cables
|
|
have had great success enabling the Raspberry Pi watchdog.
|
|
|
|
(need instruction here how to do that for various Raspberries, it differs)
|
|
|
|
Upgrades
|
|
--------
|
|
From time to time we upgrade the ubxtool receiver software. Old data also
|
|
works but typically if you upgrade, the value to the network increases.
|
|
|
|
Improving reception
|
|
-------------------
|
|
A good view of the sky can help tremendously, although as noted, we are
|
|
happy with every bit we receive. It helps to put your receiver on a "ground
|
|
plate" which is a fancy word for a piece of metal (or mesh even).
|
|
|
|
In addition, if you are in a northerly region, your view to the south is
|
|
most important. Conversely, if you are in the south, more action will be to
|
|
the north.
