SatNOGS


Summary

SatNOGS is an integral part of the Libre Space Foundation. The project aims to build a global network of satellite ground stations. It is designed as an open source participatory project based on the users operating a ground station that is accessed via a web page for all of the network users. A basic ground station can be made up of commercial off the shelf components that are commonly available with a static omnidirectional antenna, to more complex stations with multiple movable antennas.

Low Earth Orbit (LEO) satellites are our priority, and for a good reason. Hundreds of interesting projects worth of tracking and listening are happening in LEO and SatNOGS provides a robust platform for doing so. We support VHF and UHF bands for reception with our default configuration, which is easily extendable for transmission and other bands too.

Sticking to modular architecture based on network communications we ensure remote access and interchangeable design meeting all possible needs. We designed and created a global management interface (SatNOGS Network) to facilitate multiple ground station operations remotely. An observer is able to take advantage of the full network of SatNOGS ground stations around the world.

True to our values, we fuel our passion with Open Source practices in both software and hardware. Help us by contributing to the project, making it better one commit at the time.

If you would like to build your own ground station and have limited knowledge then it is recommended that you follow a non-rotator build with a simple RTL-SDR dongle and a Raspberry Pi. This will get you on to the network quickly and allow you to start scheduling observations. There are a few choices to be made but he community are available to help if you need it. More complex, movable, antenna systems can be steered with either the SatNOGS designed rotator or a commercial unit such as the Yaesu G-5500, Spid XY or similar. It is recommended that these types of builds are for more experienced operators but there is no reason why these can not be put into operation, they just require more work.

The reference design uses a Raspberry Pi + RTL-SDR dongle + either a VHF or UHF antenna. A Raspberry Pi image is available to make software installation simpler. Much of the decision making is down to personal choice but sometimes additional hardware is needed to help filter out local noise, such as strong broadcast stations. Both the community and Matrix / IRC offer support and assistance.
