Revision as of 08:01, 26 November 2017

This page assumes you have an account and a ground station registered on either network.satnogs.org or network-dev.satnogs.org. Make note of your station ID and API Key.

Intro

The Raspberry Pi 3 is the reference platform for SatNOGS. You can try using various distributions for this (eg. Arch, Fedora), but the one we suggest is our custom image based on latest Raspbian.

Fedora

Instructions for installing on Fedora can be found here.

Raspbian

Download

You can download the latest Raspbian SatNOGS image following the links from the latest tag on GitLab.

Artifacts list

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

Example:

$ sha256sum -c sha256sums 
2017-09-29-Raspbian-SatNOGS-master-lite.info: OK
image_2017-09-29-Raspbian-SatNOGS-master-lite.zip: OK

Flashing and Setup

Follow the usual Raspbian flashing instructions, and boot your Raspberry Pi.

Once your Raspberry Pi is booted, log in with username "pi" password "raspberry" and run:

sudo raspi-config

You will want to be sure to do the following:

Set a strong, unique password
Change localization settings:
- by default the rpi locale is configured for EN-GB, change as appropriate (ie: to EN_US.UTF-8)
- set timezone (we recommend UTC so your logs match the times in Network)
- set keyboard layout, again this is defaulting to a UK layout
- set wifi country
Finish and reboot

Next, run

sudo apt-get update && sudo apt-get -y upgrade

Networking

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.

Setup

SSH to the Raspberry Pi with user "pi" and password "raspberry" (no quotes).

Run "sudo satnogs-setup"
Select "Update" to update the configuration tool
Set basic configuration
Select "Apply" and the Raspberry Pi will configure itself; this may take some time
Select "Back" to exit

Note: you can always reconfigure the software by running "sudo satnogs-setup" again.

Basic setup

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 usrpb200, usrp2, airspy or hackrf; a complete list can be found here.

SATNOGS_STATION_ELEV: The elevation of your ground station in metres.

SATNOGS_STATION_ID: The ID assigned to your station in the SatNOGS network site (either stage or prod).

SATNOGS_STATION_LAT: The latitude of your station. North is positive, south is negative.

SATNOGS_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. If you don't have a rotator (like the No rotator setup), enter False.

HAMLIB_UTILS_ROT_OPTS: Options for rotcld. For a yaesu rotator, use -m 601 -r /dev/ttyACM0 -s 9600 -T 0.0.0.0

Advanced Setup

SATNOGS_CLIENT_URL: If you to try a development version of satnogs-client, you can change the URL here. The URL needs to be in PIP format. Here are some examples:
- git+https://gitlab.com/librespacefoundation/satnogs/satnogs-client.git@0 -- the '0' branch (the current development version) of satnogs-client
- git+https://gitlab.com/jdoe/satnogs-client.git@new-feature -- the 'new-feature' branch of jdoe's fork of satnogs-client

Changing this setting is not recommended unless you're developing satnogs-client itself.

Updating

To update SatNOGS software, re-run sudo satnogs-setup. Select "Update" to pull the latest Ansible playbook and then "Apply" to apply any updates.

Raspbian packages can be updated using the normal APT updating methods (e.g. apt-get upgrade or aptitude).

WARNING: An update can potentially interrupt a running observation!

Testing

To see if satnogs-client has started successfully, check the logs with journalctl:

journalctl -u satnogs-client.service

You should see entries running approximately once per minute that look like this:

You can also try visiting satnog-client's web interface. In your browser, go to http://(ip address of your raspberry pi):5000. You should see something like this:

If you see that, great -- you're ready to schedule your first observation! If not, check out the Troubleshooting page.
