Satellite tracking using GPredict and RTL-SDR

SatNOGS is an open source initiative to build a network of ground stations around the world to track satellites. Thousands of low Earth orbit (LEO) satellites are its principal focus. Its goal is to provide a toolset and tech stack (hardware and software) that is low cost and easy to build.

The project supports VHF and UHF bands for satellite reception with the default configuration. Its software automatically tracks, receives, and records satellites as they pass overhead while automatically scheduling observations and recording them to an online database shared among other participating ground observers.

For the purpose of simplicity, we will not cover how to build the whole hardware part of the system, which includes a high gain antenna, tracking motors, and a standard RTL-SDR dongle as a receiver. In our recipes, we will only use the dongle and a low-cost antenna. You are welcome to get more ambitious with the hardware. More details are at the...
