EOS SAT-1 is an optical Earth observation satellite for agricultural land monitoring by EOS Data Analytics, Inc. (hereinafter — EOS Data Analytics), a global AI-powered satellite imagery analytics provider. The space optics instrument and satellite manufacturer Dragonfly Aerospace built the satellite and equipped it with two high-resolution DragonEye cameras.
The satellite operates within the EOS SAT constellation, the first agriculture-focused satellite constellation among companies utilizing remote sensing technologies.
Overview
EOS SAT-1 is developed for EOS Data Analytics, a global provider of AI-powered satellite imagery analytics founded by Max Polyakov. It is the first satellite within the company's constellation EOS SAT. It will have a daily imaging capacity of up to 1 million square kilometers and capture imagery in 11 agri-related spectral bands.{{cite web |title=Let the Science Talk: How the EOS SAT Constellation Empowers Sustainable Agriculture |url=https://www.sciencetimes.com/articles/42047/20230126/let-the-science-talk-how-the-eos-sat-constellation-empowers-sustainable-agriculture.htm |access-date=25 March 2023}} Satellite cameras will produce panchromatic and multispectral images.
Ev
Once fully operational, the seven small optical EOS SAT satellites will cover up to 100% of the countries with the largest cropland and forest areas, 98.5% of such lands worldwide. The satellite constellation will monitor up to 12 million square kilometers daily.{{cite web |last1=Elizabeth |first1=Howell |title=Watch SpaceX launch 1st rocket of 2023 with EOS SAT-1 and 113 other satellites today! |url=https://www.space.com/watch-spacex-1st-rocket-launch-2023-transporter-6-rideshare-satellites. |website=Space.com |date=2 January 2023 |access-date=25 March 2023}}

Launch
The satellite was launched on January 3, 2023, on the SpaceX’s Transporter-6 mission.{{cite web |title=Replay! SpaceX launches 1st rocket of 2023 with EOS SAT-1 - Space.com and EOSDA Broadcast |url=https://www.youtube.com/watch?v=_XVzO2uQ_P4 |website=YouTube |publisher=VideoFromSpace |access-date=25 March 2023}} The Falcon 9 rocket lifted off from the Cape Canaveral Space Force Station (CCSFS) and launched 114 spacecraft into orbit, including the EOS SAT-1 satellite.
Mission progress
Since the launch into low Earth orbit, the EOS SAT-1 satellite has established contact and sent telemetry and data on the status of its systems to Earth.{{cite web |title=The Ukrainian EOS SAT-1 satellite made contact and transmitted telemetry |url=https://mezha.media/en/2023/01/05/the-ukrainian-eos-sat-1-satellite-made-contact-and-transmitted-telemetry/. |website=mezha.media}}
The satellite is fully operational.
