GEISAT Precursor’s Launch




On June 12th, 2023, at 21:35 UTC / 23:35 CEST, the satellite GEISAT Precursor has been successfully launched from the Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base in California, with the Transporter-8 mission onboard a SpaceX Falcon 9 rocket, a rideshare flight of small satellites to a Sun Synchronous Orbit.

The satellite is a 16U CubeSat, dedicated to CH4/GHG & Environment, and offers a resolution of 2 m in PAN+RGB+NIR bands and 5 m resolution in shortwave infrared bands, with a total of 10 bands and a swath of up to 14 km (at 500 km altitude).

The satellite is 20 centimetres wide and 40 centimetres high, with deployable solar panels and a total mass of 21 kg. It is designed to have a nominal lifetime of at least four years.

The heart of the satellite is the iSIM-90 instrument, a small camera capable of providing High-Resolution images for Earth Observation. One of the optical channels is dedicated to the visible spectrum plus NIR, while the second optical channel is dedicated to the SWIR spectrum. Both combined will be used for  methane detection applications.

The GEISAT Precursor Mission represents the first SATLANTIS end-to-end solution for methane emissions detection, point source identification, and quantification. It will be followed by a Constellation of satellites dedicated to measuring CH4 and other greenhouse gas emissions.

GEISAT Precursor was selected in 2023 to join the Copernicus programme (the European Union’s Earth Observation flagship programme) as “Copernicus Contributing Mission” (CCM), in the Category I for the Atmospheric Composistion domain.
