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.[2][3][4][5]

Overview

EOS SAT-1 is developed for EOS Data Analytics, a US-Ukrainian company founded by Max Polyakov.[6] 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.[7] 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.[8]

History

The satellite was launched on 3 January 2023, on the SpaceX’s Transporter-6 mission.[9] 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.[10]

Specifications

A single EOS SAT-1 satellite scene covers a territory that is 42 km in width and can be over 1000 km in length. The altitude of the satellite's sun-synchronous orbit is 520–560 km.[11]

Orbit average power: 140 W.

Design lifetime: 5–7 years.

Mass: 176.6400 kg.

Bus voltage: 24.5 — 33.6 V.

GSD (ground sample distance), resolution:

  • panchromatic 1.4 m
  • multispectral 2.8 m

Swath width: double optical payload with a 44 km swath width for an altitude of 500 km.

Spectral bands — 11 agri-related bands:[12]

  • RGB
  • 2 NIR bands
  • 3 RedEdge bands
  • WaterVapor
  • Aerosol
  • Pan
