Minimize Mission Operations Overview

A timeline providing the main Proba-V mission operations events is provided here after:

  • Launch and Early Operations Phase (7 - 17 May 2013): The PROBA-V satellite was launched on Tuesday 7 May 2013 at 04:06 CEST in Kourou (French Guyana) with ESA's new launch vehicle, the Vega launcher. PROBA-V was deployed into its Sun-synchronous near-polar orbit at 820 km altitude, just 55 minutes after launch. First raw image from the Proba-V sensor was succesfully acquired over France's west coast on 15 May 2013. Analysis of the first image quality confirms that the sensor was in good health and ready for the commissioning phase. 
  • Commissioning Phase (17 May 2013 - 3 December 2013): after the launch and initial in-flight verification phase, the 6 months Commissioning of the satellite started, where payloads and systems are gradually activated and their performance validated. This included a careful cross-calibration of the Vegetation imager with the previous generation of the instrument, operating on France's Spot-5 satellite, to ensure data compatibility. Radiometric and geometric calibration was also executed. With the successful Commissioning Phase the satellite started its nominal operations lifetime.
  • Operations Phase (3 December 2013 onward): the nominal OperationsPhase started after the Commissioning of the satellite with a nominal lifetime of 2.5 years (with potential extension up to a total of 5 years). 


Main Mission News

The main mission news are reported here below, additional news and mission information is available on the dedicated ESA page and VITO page.

  • Proba-V Collection 1 dataset reprocessing completed (February 2017):
    The Proba-V re-processing campaign, using the latest Processor has been completed.The new Collection 1 or C1 data set includes significant quality improvements with respect to previous data version Collection0 (C0):  re-fined radiometric calibration parameters, metadata compliancy to Climate and Forecasting convention (v1.6), and a new Cloud Detection Algorithm.  In addition, the intermediate L2a products will be made available with this reprocessing.

    The new C1 dataset is identified by the new version number "V101", replacing the old "V001"used previously.

  • Release of Proba-V L2A products to users (February 2017):
    the intermediate Proba-V Level 2A (L2A) Top-of-Atmosphere products were made available with the release of the Proba-V Collection 1 (C1) reprocessed dataset. A Level 2A product contains radiometrically and geometrically corrected TOA reflectance values, projected to a Plate Carrée grid. The L2A products are provided per band/camera. 

  • Release of GeoTiff products to users (September 2015):
    In order to facilitate the use of Proba-V data, all of the products were made available in both GeoTiff and HDF5 format. GeoTiff is a worldwide raster metadata standard that allows for embedding georeferencing information and is supported by most GIS software packages, such as Quantum GIS, ArcGIS, ERDAS IMAGINE, and ENVI. As for HDF5, also in GeoTiff separate Proba-V data can be stitched into a single file during ordering. 
  • Release of Proba-V 100 m to users (March 2015):
    Proba-V 100 m measurements of the central camera (500km swath, 5 days revisit time) were made available to the users as 1-day and 5-days synthesis products, both TOA and TOC reflectances are provided to the users. An example of Proba-V 100m image is provided here below, a gallery of Proba-V images is available in the VITO web site
  • Hand-over from SPOT-VGT to Proba-V (31 May 2014):
    The SPOT Vegetation mission, flown on SPOT-4 and SPOT-5 for 16 years, marked 16 years of service in May, the last SPOT-VGT mission was officially ended on 31 May 2014. As of June 1, 2014, Proba-V is the official SPOT-VGT successor mission, mapping land cover and vegetation growth across the entire planet every two days. The one year of overlap allows to perform a carfeul cross-calibration between the two sensors, ensuring a consistent time series for scientists to employ seamlessly.
