Abstract :
[en] PROBA-V has been successfully launched on 7th May 2013 and is providing a global monitoring in the
continuity of the SPOT-VEGETATION mission. The progress in terms of ground resolution between Spot VGT
and PROBA-V is a factor 3 (1 km to 1/3 km ground resolution product). The User Community requirements for
the next generation of global monitoring are a 100 m ground resolution product. This means an additional factor
3 improvement, but in a short time frame (5 years). After success of the PROBA-V mission, the Belgian Science
Policy (BELSPO) initiates a PROBA-V Successor feasibility study. This study was undertaken by VITO and
CSL to identify potential tracks to achieve a follow-on mission which is expected to be relevant for the User
Community. The mission analyses for each of these tracks was evaluated. Today the PROBA-V mission
lifetime is expected to expire by mid of 2018. Since the interest for global land monitoring is expected to
continue in the future, this study proposes mission requirements and a shortlist of optimal mission scenarios for
a follow-on mission in this short time frame. The goal of such a new PROBA-V mission is clear: it should
ensure the data continuity of global vegetation monitoring, while taking the opportunity to further improve the
data quality. Data continuity is essential for understanding long term trends of land use that may affect the
global equilibrium of the planet (in the context of scarcity for land or food, natural disasters, climate change).
As for added value, a fine example is the improvement of spatial resolution when comparing PROBA-V with
the spatial resolution in SPOT-VEGETATION products. An improvement in spatial resolution towards a full
100m product is considered by the user community as the main target for a PROBA-V follow-on mission.
