PROBA-V objectives


The main mission requirements of PROBA-V remote-sensing satellite are:

  • Data and service continuity: filling the gap between the SPOT-VGT and the Copernicus Sentinel-3 missions, with spectral and radiometric performance identical or better than SPOT-VGT
  • Spatial resolution: 1 km mandatory, improved Ground Sampling Distance (GSD) is highly desirable: 300 m (VNIR bands), 600 m (SWIR band). Image quality and geometric accuracy, equal to or better than SPOT-VGT
  • Provision of daily global coverage of the land masses in the latitudes 35° and 75° North and in the latitudes between 35° and 56° South, with a 90% daily coverage of equatorial zones - and 100% two-daily imaging, during day time, of the land masses in the latitudes between 35° North and 35° South.
Additional details on PROBA-V Mission Requirements can be found in the MRD.

PROBA-V principally addresses key observations in the following application domains:
  • General land use in relation to vegetation cover and its changes
  • Vegetation behaviour to strong meteorological events (severe droughts) and climate changes (long-term behaviour of the vegetation cover)
  • Disaster management (detection of burnt areas and water bodies)
  • Biophysical parameters for model input devoted to water budgets and primary productivity (agriculture, ecosystem vulnerability, etc.).

The minisatellite provides data to the instrument’s worldwide user community of scientists and service providers within ESA's Earth Observation Programme. Vital uses of PROBA-V Vegetation data include day-by-day tracking of extreme weather, alerting authorities to crop failures, monitoring inland water resources and tracing the steady spread of deserts and deforestation.
