SatNOGS is an integral part of the Libre Space Foundation . The project aims to build a global network of satellite ground stations. Designed as an open source participatory project which is straightforward to build using commonly available parts and some 3D printed elements. A ground station is built to interact with a website that holds key satellite information. The web interface allows a user to schedule a satellite observation of any of the networked ground stations.
Here you can find more information on how to get started with SatNOGS, building and operating a satellite ground station and joining the SatNOGS Network.
A SatNOGS ground station can be made in a variety of ways. The reference design uses a Raspberry Pi and RTL-SDR dongle with either stationary antennas or either a SatNOGS rotator or a commercial amateur radio rotator. There is provision to use amateur radio transceivers or alternative SDR technology. The image below explains the system.The image below explains the system.
