GEOSAT-2 (former Deimos-2) is an Earth-imaging satellite, built for GEOSAT of Spain, which launched 19 June 2014 and remains operational.
It is the second satellite of the GEOSAT Earth Observation system, following GEOSAT-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.
|Orbit Height||620 km|
|Orbit Type||Sun synchronous|
|Local Time at Ascending Node||10:30|
|Revisit Time||2 days worldwide|
GEOSAT-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.

ESA is offering, for scientific research and application development, access to Full archive and New Tasking of GEOSAT-2 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.
ESA offers registered users the access to the Online Dissemination server to the following data collections
