Libre Space Foundation Raspberry Pi Case, on thingiverse

Introduction

The Raspberry Pi (version 3 and 4) is the reference platform for SatNOGS (see our Ansible guide to install SatNOGS on other Linux machines). You can try using various distributions for this (eg. Debian/Armbian, Arch, Fedora), but the one we suggest is our custom image based on latest Raspbian.

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.

Download

Raspbian SatNOGS Image: artifacts.zip (Release: 2022091000)

Download the latest Raspbian SatNOGS Image from above (or via the "Download" icon on the right side of the latest tag page on GitLab). This image has the SatNOGS setup script installed, the SSH server enabled and all required packages preinstalled. You will get an artifacts.zip file with the following content:

A Zipped image file
An Image info file
A SHA256 checksum file

Data integrity verification

You should verify the data integrity of the artifacts by comparing the SHA256 checksums. On Linux, run sha256sum -c sha256sums in the directory where the artifacts are downloaded and unzipped.

Example:

$ sha256sum -c sha256sums 
2022-09-10-Raspbian-SatNOGS-master-lite.info: OK
image_2022-09-10-Raspbian-SatNOGS-master-lite.zip: OK

Flashing

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

Getting console access

You can log in the Raspberry Pi by connecting it to a keyboard and monitor or through network via an SSH connection.

Keyboard and monitor

Once your Raspberry Pi is booted, log in with username "pi" password "raspberry".

Ethernet

If you are using wired Ethernet you should get connectivity right away. You just need to find the IP address of Raspberry Pi (e.g. in your router management interface). Log in with SSH using username "pi" password "raspberry", for example:

$ ssh pi@192.168.1.2

If your network supports zeroconf, then you can use the hostname of your Pi:

$ ssh pi@raspberrypi.local

Pre-boot wireless configuration

If neither keyboard/monitor, nor a wired Ethernet are available, you can set up a WiFi connection before boot by mounting the boot partition of the flashed SD card and editing files directly. Note your OS may mount boot partition in a different location. Windows users have line ending problems. Suggested actions:

$ $EDITOR /media/Raspbian_SatNOGS-boot/wpa_supplicant.conf

contents: (note key_mgmt options include NONE, WPA-PSK, WPA-EAP)

   ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
   update_config=1
   country=US
   
   network={
       ssid="NETWORK_NAME"
       psk="password"
       key_mgmt=WPA-PSK
   }

Pre-boot user creation

The latest version of Raspberry Pi OS, of which the SatNOGS image is based on, does not have the "pi" user already upon first boot.

If you wish to login using ssh upon the first boot with the prior default username / password of "pi" / "raspberry", then:

Create the file userconf.txt in the root of the boot partition of the uSD card.
Its contents should be the single line:
- pi:$6$/XOZsG1X0IAbhXB0$wYZHRkvib0SUKQA3KVAxofPR.JsFAbI2NCue2znGvhRsQobVdllFXyQZ7fMSvAoyEj8MfHtkMeSZT7IRIixg01
- (the format is username:encrypted-password)

Configuration

Raspberry Pi Setup

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; UTC is under the 'none of the above' submenu)
- set keyboard layout, again this is defaulting to a UK layout
- set wifi country
- expand filesystem (under the Advanced menu)
Configure network or WiFi (see this doc for network configuration instructions)
Finish and reboot

SatNOGS Setup

SSH to the Raspberry Pi with user "pi" and your new password.

Follow SatNOGS Client Setup instructions to configure the system.
