An isae-supaero image detector in the geo-kompsat-2b satellite (geostationary – korea multi-purpose satellite-2))
The LARGO7M detector is a 7-million-pixel image sensor that supplies 2500km x 2500km images centered on South Korea, with 250-m resolution in different spectral bands (colors) ranging from 370nm to 900nm. It is used to observe, quantify and predict short-term changes in the coastal environment around Korea. The GEO-KOMPSAT-2B satellite was put into orbit on February 18th, 2020.
Mission Lifetime: 10 years
Position: Geostationary orbit, 35,786 km above the Earth.
Spectral Bands: 12 bands – in the visible spectrum.
Ground resolution: 250m x 250m – above Korea.
Target surface area: 2500km x 2500km
ADS integrates the image sensor into its proximity electronics and then places it in the telescope. A filter wheel selects the 12 spectral bands by placing a colored filter in front of the 7-million-pixel image sensor.

An isae-supaero image detector in the coms satellite (communication, ocean and meteorological satellite)
The COBRA2M detector is a 2-million-pixel image sensor that provides 2500km x 2500km images centered on South Korea, with resolution of 500m in 8 different spectral bands (colors) ranging from 400nm to 900nm. It is used to observe, quantify and predict short-term changes in the coastal environment around Korea. The COMS satellite was put into orbit on June 27th, 2010.
Mission Lifetime: 7 years
Position: Geostationary orbit, 35,786 km above the Earth.
Spectral Bands: 8 bands in the visible spectrum.
Ground Resolution: 500m x 500m above Korea.
Target surface: 2500km x 2500km

An isae-supaero image detector in the sentinel 2a and 2b satellites
The VNIR S2 image detector is a low-noise, multi-strip image sensor (contract in partnership with ADS and ESA). This sensor is embedded in two Sentinel 2 satellites that observe all emerged land every 10 days, with resolution of 10m to 60m, in 13 spectral bands ranging from the visible to the mid-infrared spectra.
The data are mainly used in the areas of agriculture, forestry, land-use determination, habitat characterization and biodiversity. They are also used to observe and prevent natural disasters such as flooding, volcanic eruptions, ground subsidence and landslides. The Sentinel-2A and Sentinel-2B satellites were put into orbit on June 23rd, 2015, and March 7th, 2017, respectively.

An isae-supaero image detector in an airplane to establish an optical link with the geostationary satellite, artemis
The LOLA (Liaison Optique Laser Aéroportée – Airborne Laser Optical Link) project helped to establish an optical link through the atmosphere between a Mystère XX airplane and ESA’s ARTEMIS geostationary satellite (ADS as prime contractor). The CMOS APS 750 FAST sensor detects and follows the satellite with the weak optical power received. The communication beam’s wavelength is 850nm.
