About GEOSAT-1

GEOSAT-1 (formerly Deimos-1) is an Earth-imaging microsatellite, built for Elecnor Deimos of Spain, which launched on 29 July 2009 and remains operational. It is now owned and operated by GEOSAT.

It is part of a group of satellites collectively known as the Disaster Monitoring Constellation (DMC) and was the first private European Earth observation satellite launched.

GEOSAT-1 Objectives

The GEOSAT-1 mission objectives are commercial with the optical satellite images aimed at services and applications in maritime, agriculture, environment and forestry within the Iberian Peninsula region and Europe.

There is a common design of the GEOSAT-1 and UK-DMC-2 spacecraft. Both spacecraft are developed to carry out a commercially-focused operational imaging mission, supporting rapid-response, large-area mapping for a range of applications.

GEOSAT-1 Instruments

Multi-Spectral Camera (MSC/SLIM6)

The MSC instrument on board GEOSAT-1 is a multi-spectral imager with a resolution of 22 metres and 650 kilometres of swath, operating in green, red and near-infrared spectra. A key objective met by the instrument is delivering complete coverage of Spain and Portugal every five days.

GEOSAT-1 Data

DATA COLLECTIONS

ESA is offering, for scientific research and application development, access to Full archive and New Tasking of GEOSAT-1 data upon submission and acceptance of a project proposal. These products are available as part of the GEOSAT.

ESA will support as many high-quality and innovative projects as possible within the quota limit available, therefore, for the "on demand" TPM, only a limited amount of products can be made available to each project.
