Deimos-2

Mission

blue arrow Mission Overview

Deimos-2 is an Earth-imaging satellite built for Elecnor Deimos of Spain which launched 19 June 2014 and remains operational.
It is the second satellite of the Deimos Earth Observation system, following Deimos-1. The expected mission lifetime is at least seven years.

A high resolution satellite, it became the first European fully-private satellite capable of providing sub-metric multispectral imagery.

Deimos-2 Mission Parameters
Orbit Height 620 km
Orbit Type Sun synchronous
Local time at ascending node 10:30
Revisit time 2 days worldwide

blue arrow Mission Objectives

Deimos-2 was designed to provide a cost-effective and highly responsive service to cope with the increasing need of fast access to sub-metric imagery.
It provides near-real time image tasking, downloading, processing and delivery to the end user.
It has a collection capacity of more than 150,000 km2/day with a two day average revisit time worldwide - one day at mid-latitudes.

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

blue arrow DATA DESCRIPTION

ESA is offering, for scientific research and application development, access to Full archive and New Tasking of Deimos2 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.

Collections available:

ESA offers registered users the access to the Online Dissemination server to the following data collections

  • Deimos-1 and 2 ESA archive: Level 1 product that ESA collected over the years. The dataset regularly grows as ESA collects new products.
