blue arrow Mission Overview


Deimos-1 is an Earth-imaging microsatellite built for Elecnor Deimos of Spain which launched on 29 July 2009 and remains operational.

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


Deimos-1 mission parameters
Orbit Height 663 km
Orbit Type Sun-synchronous near-circular
Orbit inclination 81°
Revisit time Daily coverage at a resolution that enables
effective monitoring of the rapidly changing environment

blue arrow Mission Objectives

The Deimos-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 Deimos-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.

blue arrow Instruments

Multi-Spectral Camera (MSC/SLIM6)

The MSC instrument on board Deimos-1 is a multi-spectral imager with a resolution of 22 metres and 625 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.

blue arrow DATA DOWNLOAD

You can directly download Deimos data from a number of online dissemination systems. All data is freely available to registered EO-SSO users.

Download data from the Third Party Missions through the ESA TPM Online Dissemination system:

  • TPM LOADS - offers access to Deimos-1 and 2 collections


ESA is offering, for scientific research and application development, access to Full archive and New Tasking of Deimos1 data upon submission and acceptance of project proposal. These products are available as part of the Deimos Imagery.

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.
