Overview
SatNOGS aims to provide a stack of technologies needed for a distributed network of
low Earth orbit
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never mor ...
satellite ground stations. In order to implement such a stack the four following different sub-projects are developed
Network
SatNOGS Network is a web application for scheduling observations across the network of ground stations.
Database
SatNOGS Database is a crowd-sourced application allowing its users to suggest satellite transmitter information for currently active satellites. Its data is available via an
API
An application programming interface (API) is a way for two or more computer programs to communicate with each other. It is a type of software Interface (computing), interface, offering a service to other pieces of software. A document or standa ...

Client
SatNOGS Client is the software to run on ground stations, usually on embedded systems, that receives the scheduled observations from the Network, receives the satellite transmission and sends it back to the Network web app.
Ground Station
SatNOGS Ground Station is an open source hardware ground station instrumentation with a rotator, antennas, electronics and connected to the Client. It is based on

Operation
A November 2019 SatNOGS blog post summarizes total statistics since establishment:
* 300+ operational ground-stations
* 12,000,000+ observations
* 380+ satellites with 810+ transmitters monitored
* 51,000,000+ data frames
Tracking
The global array of ground stations contribute to an effective network for monitoring orbital satellites.
