Minimize Proba-V
Web Content Image

The Proba-V mission provides multispectral images to study the evolution of the vegetation cover on a daily and global basis. The 'V' stands for Vegetation. This mission is extending the data set of the long-established Vegetation instrument, flown as a secondary payload aboard France's SPOT-4 and SPOT-5 satellites launched in 1998 and 2002 respectively. The latter satellite's Vegetation instrument remains operational to this day, and is expected to remain operational until Q1/2015.

The mission, developed as part of ESA's Proba Programme, is an ESA EO mission providing global coverage every two days, with latitudes 35-75°N and 35-56°S covered daily, and between 35°N and 35°S every 2 days. The Proba-V imager's continent-spanning 2250 km field of view collects light in the blue, red, near-infrared and mid-infrared wavebands, ideal for monitoring plant and forest growth as well as inland water bodies. The Vegetation instrument can distinguish between different land cover types and plant species, including crops, to reveal their health, as well as detect water bodies and vegetation burn scars.

The SPOT Vegetation dataset has close to 10,000 registered users around the globe and has contributed to hundreds of scientific papers over 15 years. But with further SPOT satellites lacking the capacity to carry Vegetation instruments, Proba-V has been designed to meet the future needs of this group.

The Proba-V mission has been developed in the frame of the ESA General Support Technology Program (GSTP). The Contributors to the Proba-V mission are Belgium, Luxembourg and Canada.

The ESA Earth Watch Programme provides 1km data, which is complemented by a National Programme supplying products at 300m/600m resolution (available as ESA Third Party Mission).

Proba-V 100 m products now publicly available

13 March 2015

VITO has announced that Proba-V 100 m products are now publicly available as 1-day and 5-day syntheses from their Product Distribution Portal.

The 100 m products will open new possibilities for global and regional environmental monitoring, as well as for agricultural applications where information at parcel level becomes available.

Minimize Mission Objectives

The objective of the Proba-V Mission is to provide multispectral images to study the evolution of the vegetation cover on a daily and global basis, in continuation of the Vegetation instrument on board SPOT-4 and SPOT-5.

The data produced by Proba-V cover operational information needs related to:

  • Environmental & agro-climatic conditions
  • Effects of extreme events as drought and floods
  • Natural resources (soil, water, rangeland)
  • Crop and livestock production; prevalence of diseases
  • Desertification
  • Etc.

This information can in turn be used in a socio-economic context (trade and markets; consumer prices; food intake; nutrition and health status, demographics) or for preventing/mitigating food scarcity events. Examples of current operational use of the SPOT-VEGETATION data are e.g.:

  • the GMFS service under the Copernicus Service Element of the EW programme
  • The Geoland-2 Copernicus Service project
  • The Copernicus downstream Service MS-Monina
  • The National Service UK Forestry Commission
  • MARS project in JRC

The mission has been designed to meet the user requirements expressed by an International User Committee (IUC), incorporating representative users of the current SPOT-VEGETATION missions.

Minimize Satellite

Proba-V is a miniaturised ESA satellite tasked with a full-scale mission: to map land cover and vegetation growth across the entire planet every two days. It is the latest in ESA's Proba series of minisatellites, among the smallest satellites launched by the agency - each one less than a cubic metre in volume.

It operates on a sun-synchronous near polar Earth orbit at about 820 km guaranteeing the required swath of 2250 km with an instrument field of view of 102 degrees, compatible with the geographical coverage.

The Proba-V satellite carries a new Vegetation instrument, as single operational payload.

In the frame of the In Orbit Demonstration, the Proba-V platform also flies 5 technological payloads:

  • A X-Band transmitter based on the new GaN RF amplifier
  • An Energetic Particle Telescope (EPT), demonstrating a new type of radiation monitoring sensors and acquisition system
  • An Automatic Dependent Surveillance Broadcast (ADS-B) receiver, demonstrating potential air traffic surveillance from LEO satellites
  • A SATRAM radiation monitoring system, complementing EPT
  • HERMOD (fibre optic connectivity in-situ testing)

The main satellite features are listed below:
