Minimize Mission and Sensor Description

The main PROBA-V payload is the Vegetation sensor: a multispectral pushbroom spectrometer with 4 spectral bands and with a very large swath of 2285 km to guarantee daily coverage above 35° latitude.

The payload consists of 3 identical cameras, each with a very compact Three Mirror Anastigmat (TMA) telescope. Each TMA, having a FOV of 34°, contains 4 spectral bands: 3 bands in the visible range (Blue, Red and NIR) and one band in the SWIR spectral range. The swath Total FOV is 103°. VGT-P is restricted to imaging land and dedicated calibration zones. On-board the spacecraft, there is for each camera a land sea mask that allow to remove the pixels that contain only sea and it dictates when each camera should be in imaging mode.

An illustration of the PROBA-V platform and a table summarising the main instrument parameters of the Vegetation instrument, compared to its predecessor (SPOT-VGT) are provided here below.

Minimize Mission Requirements

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

  • Data and service continuity: filling the gap between SPOT-VGT and the Sentinel-3 mission, 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 behavior to strong meteorological events (severe droughts) and climate changes (long-term behavior 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.).
