SatNOGS (Satellite Networked Open Ground Station) project is a free software and open source hardware platform aimed to create a satellite ground station network. The scope of the project is to create a full stack of open technologies based on open standards, and the construction of a full ground station as a showcase of the stack.{{cite web|title=Hackaday: SatNOGS |url=https://hackaday.io/project/1340-satnogs-global-network-of-ground-stations}}{{full citation needed|date=December 2018}}{{Cite journal |last1=Poblet|first1=Marta |last2=Fünfgeld|first2=Hartmut |last3=McShane|first3=Ian |date=2014-11-30 |title=Telecommunications and disaster management |journal=Australian Journal of Telecommunications and the Digital Economy |language=en| volume=2 |issue=4 |doi=10.7790/ajtde.v2n4.73}}{{Cite web |url=https://digitalcommons.usu.edu/cgi/viewcontent.cgi?article=4125&context=smallsat |title=Overview of the Satellite Networked Open Ground Stations (SatNOGS) Project |last=Dan|first=White |date=2018 |website=32nd Annual AIAA/USU Conference on Small Satellites |access-date=19 December 2018}}
History
The SatNOGS project was initiated during NASA SpaceApps Challenge in 2014 at Athens Hackerspace.{{cite web|title=SatNOGS at NASA Space Apps Challenge|url=https://2014.spaceappschallenge.org/project/satnogs/}} The project then took part in and won the first place of the Hackaday Prize 2014 competition.{{cite web|title=SatNOGS Wins the 2014 Hackaday Prize|url=http://hackaday.com/2014/11/13/satnogs-wins-the-2014-hackaday-prize/|date=November 2014}} SatNOGS is currently a project of the Libre Space Foundation.{{Cite web|url=https://libre.space/projects/satnogs/|title=SatNOGS|website=Libre Space Foundation|language=en-US|access-date=2018-12-20}}
Overview
SatNOGS aims to provide a stack of technologies needed for a distributed network of low Earth orbit satellite ground stations. In order to implement such a stack the four following different sub-projects are developed{{clarify|date=December 2018}}
= Network =
SatNOGS Network is a web application for scheduling observations across the network of ground stations.{{cite web|title=SatNOGS Network source code|url=https://gitlab.com/librespacefoundation/satnogs/satnogs-network}}{{Cite web|url=https://teonite.com/blog/you-probably-have-never-heard-about-satnogs-and-this-is-why-you-should/|title=You probably have never heard about SatNOGS and this is why you should|date=2018-06-12|website=TEONITE|access-date=2018-12-20|archive-date=2018-12-21|archive-url=https://web.archive.org/web/20181221041316/https://teonite.com/blog/you-probably-have-never-heard-about-satnogs-and-this-is-why-you-should/|url-status=dead}}{{full citation needed|date=December 2018}}
= Database =
SatNOGS Database is a crowd-sourced application allowing its users to suggest{{vague|date=October 2017|reason= cryptic, in fact}} satellite transmitter information for currently active satellites. Its data is available via an API.{{clarify|date=December 2018}}{{Cite web|url=https://satnogs.readthedocs.io/en/stable/satnogs-db/docs/api.html|title=API — SatNOGS 1 documentation|website=satnogs.readthedocs.io|access-date=2018-12-20}}
= 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.{{cite web|title=SatNOGS Client source code|url=https://gitlab.com/librespacefoundation/satnogs/satnogs-client}}{{Cite web|url=https://www.gnuradio.org/grcon-2018/keynotes/|title=GNU Radio Conference 2018 Keynotes}}{{Dead link|date=March 2023 |bot=InternetArchiveBot |fix-attempted=yes }}
= Ground Station =
SatNOGS Ground Station is an open source hardware ground station instrumentation with a rotator,{{cite web|title=SatNOGS Rotator source code|url=https://gitlab.com/librespacefoundation/satnogs/satnogs-rotator}} antennas,{{cite web|title=SatNOGS Antennas source code|url=https://gitlab.com/librespacefoundation/satnogs/satnogs-antennas}} electronics{{cite web|title=SatNOGS Rotator Controller source code|url=https://gitlab.com/librespacefoundation/satnogs/satnogs-rotator-controller}}{{full citation needed|date=December 2018}} and connected to the Client. It is based on 3D printed components, readily available materials.{{citation needed|date=March 2019}}
Operation
A November 2019 SatNOGS blog post summarizes total statistics since establishment:{{Cite web|url=https://satnogs.org/2019/11/5yrs-hackadayprize/|title=5 years after winning the Hackaday prize|date=2019-11-14|website=SatNOGS|access-date=2019-12-19}}
- 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.{{Cite web|url=https://satnogs.org/about/|title=About • SatNOGS|website=SatNOGS|date=6 January 2015|access-date=2019-12-19}}
The European Space Agency utilized the SatNOGS network to gain initial status observations from the OPS-SAT CubeSat after launch in December 2019.{{cite tweet|user=esaoperations|author-link=European Space Agency|number=1207315749859209216|date=18 December 2019|title=And grateful thanks to @Coastal8049 and his fellow @SatNOGS team members for giving us our first indication the newborn #OPSSAT satellite was alive and well!}}
