The Raspberry Pi 3 is the reference platform for SatNOGS. As of September 2017, there are two methods of installing the SatNOGS client on a Raspberry Pi:
- Using Fedora for ARM, and following the instructions at satnogs.readthedocs.io
- Installing the custom-built SatNOGS Raspbian image
- If you run into anything in the instructions that is unclear, please submit an issue against the documentation repository.
The latest Raspbian SatNOGS image artifacts can be downloaded from GitLab.
The current artifacts list consists of:
- A Zipped image file
- An Image info file
- A SHA256 checksums file
Data integrity verification
You should verify the data integrity of the artifacts by checking the SHA256 checksums. On Linux, run
sha256sum -c sha256sums in the directory where the artifacts are downloaded
$ sha256sum -c sha256sums 2017-09-10-Raspbian-SatNOGS-master-lite.info: OK image_2017-09-10-Raspbian-SatNOGS-master-lite.zip: OK
Follow the usual Raspbian flashing instructions, and boot your Raspberry Pi.
If you are using wired Ethernet you should get connectivity right away. If you are using wireless then see this doc for network configuration instructions.
SSH to the Raspberry Pi with user "pi" and password "raspberry" (no quotes). Run "sudo satnogs-setup" to set basic configuration. Select "quit" when you are finished, and the Raspberry Pi will reconfigure itself; this may take some time.
- Note: you can always reconfigure the software by running "sudo satnogs-setup -n" again.
- Note: You may find further details about the following options on the satnogs.readthedocs.io page.
- SATNOGS_API_TOKEN: The API token assigned to your ground station on the SatNOGS Network website.
- SATNOGS_NETWORK_API_URL: The API for the SatNOGS network site. If you're working on the stage environment, this is https://network-dev.satnogs.org/api/; if you're working on the prod environment, this is https://network.satnogs.org/api/.
- SATNOGS_RX_DEVICE: If you are using an RTL-SDR, this is
rtlsdr. Other devices supported by gr-satnogs include
hackrf; a complete list can be found here.
- SATNOTS_STATION_ELEV: The elevation of your ground station in metres.
- SATNOTS_STATION_ID: The ID assigned to your station in the SatNOGS network site (either stage or prod).
- SATNOTS_STATION_LAT: The latitude of your station. North is positive, south is negative.
- SATNOTS_STATION_LONG: The longitude of your station. East is positive, west is negative.
- HAMLIB_UTILS_ROT_ENABLED: Whether or not to enable the Hamlibs rotator daemon. Rotctld is a software daemon that provides a network server to control a rotator on a serial port. Note: even if you do not have a rotator, you'll want to enable this; see the next option for details.
- HAMLIB_UTILS_ROT_OPTS: Options for rotcld. If you don't have a rotator, set this to
-m 1; see here for details.
To update SatNOGS software, re-run
sudo satnogs-setup. This will pull the latest Ansible playbook and update if necessary.
Raspbian packages can be updated using the normal APT updating methods (e.g.
apt-get upgrade or
