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.[2] 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.[3]
Specifications
A single EOS SAT-1 satellite scene covers a territory that is 42 km in width and can be over 1 km in length.
The altitude of the satellite's sun-synchronous orbit is 520–560 km.[4]
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:[5]
- RGB
- 2 NIR bands
- 3 RedEdge bands
- WaterVapor
- Aerosol
- Pan.
Launch
The satellite was launched on January 3, 2023, on the SpaceX’s Transporter-6 mission.[6] 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.[7]
The satellite is undergoing 3-month testing before it becomes fully operational. EOS Data Analytics plans to provide the first EOS SAT-1 satellite images in April 2023.
