Hardware

The following hardware is required:

Please check recommended bill of materials. This is very basic setup, but it is guaranteed to be working.

Software

  1. Install r2cloud

    • From the image. This is the easiest way to install r2cloud on Raspberry PI. It will require brand new SD card:

    • Download the latest official image

    • Insert SD card into the card reader and flash it. You could use Etcher to do this

    • Insert SD card into the card reader and create file r2cloud.txt in the root directory. This file should contain any random string. This string is a login token. This token will be used during initial setup.

    • Or from repository binaries. Suitable for Ubuntu or Debian:

    • Login via SSH and create r2cloud.txt file in /boot directory. This file should contain any random string. This string is a login token. This token will be used during initial setup.

    • Execute the following commands:

      sudo apt-get install curl lsb-release
      curl -fsSL https://leosatdata.com/r2cloud.gpg.key | sudo gpg --dearmor -o /usr/share/keyrings/r2cloud.gpg
      sudo bash -c "echo 'deb [signed-by=/usr/share/keyrings/r2cloud.gpg] http://apt.leosatdata.com $(lsb_release --codename --short) main' > /etc/apt/sources.list.d/r2cloud.list"
      sudo apt-get update
      sudo apt-get install r2cloud
  2. Open https://raspberrypi.local address.
  3. Accept self-signed certificate. This is unique certificate that was generated during installation.

What to do next?

  1. Configure the station
  2. Select satellites for observation based on their frequency / your personal preferences
  3. Wait for several observations to happen
  4. Analyze the results using "Spectogram" feature and number of frames. The more frames - the better!
  5. Tune your software configuration and hardware setup for better performance
  6. Install rotator to maximize signal strength
  7. Setup additional LNAs or band pass filters
  8. Help tracking just launched satellites
  9. Share the data with community using leosatdata.com integrations
