EOS SAT-1 is an optical Earth observation satellite for agricultural land monitoring by EOS Data Analytics, a 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. It is the first satellite within the planned EOS SAT agriculture-focused satellite constellation.
Overview EOS SAT-1 is developed for EOS Data Analytics, a US-Ukrainian company founded by Max Polyakov. It is the first satellite within the company's planned 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. Satellite cameras will produce panchromatic and multispectral images.
Satellite constellation 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.
History The satellite was launched on 3 January 2023, on the SpaceX’s Transporter-6 mission. 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. 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.
