blue arrow Mission Overview

SPOT 5 (Satellite pour l'Observation de la Terre) was a commercial Earth-imaging satellite from CNES in France. It was launched on 4 May 2002 and ceased operations after a malfunction in March 2015.

Mission Parameters
Orbit Height 832 km
Orbit Type Sun-synchronous circular polar
Orbit Duration 101 mins
Repeat Cycle 26 days

blue arrow Mission Objectives

SPOT 5, like all the SPOT missions, was aimed at supplying high-resolution, wide-area optical imagery. This was designed to improve the knowledge and management of Earth's resources, detecting and forecasting phenomena involving climatology and oceanography, and monitoring human activities and natural phenomena. SPOT 5 had the particular goal to ensure continuity of services for customers and to improve the quality of data and images provided by the previous SPOT missions by anticipating changes in market requirements.

High-Resolution Geometric (HRG)

SPOT 5 had two HRG instruments that were deduced from the HRVIR of SPOT 4. They offered a higher resolution of 2.5 to 5 metres in panchromatic mode and 10 metres in multispectral mode (20 metre on short wave infrared 1.58 – 1.75 µm). Both instruments were able to operate in two modes, either simultaniously or individually; they had a swath of 117 km2   if operated simultaniously with an overlap of 3km2. 

The HRG instrumant had an oblique viewing capability of 27° on each side of the local vertical.

High-Resolution Stereoscopic (HRS)

The HRS imaging instrument operated in panchromatic mode and pointed forward and backward enabling it to take stereo pair images to show map relief with scene lengths up to 600km. SPOT 5 provided imagery with a swath of 120 km2.

Other Instruments

Vegetation-2: With some minor improvements regarding instrument operations, the Vegetation-2 instrument (VTG-2) is identical in its technical specification to Vegetation flown on SPOT 4.  This instrument can cover almost all Earth’s surface in a day because of its swath size of 2250 km. It captures reflected light in four spectral bands (blue, red, near-infrared, and middle-infrared).

blue arrow DATA DESCRIPTION

ESA is offering access to the SPOTMaps 2.5 dataset for scientific research and application development. Access is only available to submitted proposals that are accepted.

As many as possible of the high-quality and innovative proposals submitted will be supported within the quota limit available therefore, only a limited amount of products can be made available to each project.

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

  • SPOT 1 - SPOT 5 ESA archive: The SPOT 1 to 5 ESA archive consists of imagery over Europe and Africa that has been collected over the years along with worldwide coverage.
  • SPOT 4-5 Take5 ESA archive: ESA collection of SPOT-4 and SPOT-5 Level 1C and 2A products acquired during the Take5 experiment.
  • Image 2006 European coverage: SPOT-4, SPOT-5 and IRS-P6 cloud-free coverage acquired in 2006 over 38 European countries.
