PROBA-V 1 km, 333 m, and 100 m products
The PROBA-V VEGETATION Raw products and Synthesis products provided coverage of all significant landmasses worldwide with, in the case of a 10-day synthesis product, a minimum effect of cloud cover, resulting from selection of cloud-free acquisitions during the 10-day period. It provided a daily coverage between Latitudes 35°N and 75°N, and between 35°S and 56°S, and a full coverage every two days at the equator. The VEGETATION instrument was pre-programmed with an indefinite repeated sequence of acquisitions. This nominal acquisition scenario allowed a continuous series of identical products to be generated, with the goal to map land cover and vegetation growth across the entire planet every two days.

WorldView-1 full archive and tasking
WorldView-1 high resolution optical products are available as part of the Maxar Standard Satellite Imagery products from the QuickBird, WorldView-1/-2/-3/-4, and GeoEye-1 satellites. All details about the data provision, data access conditions and quota assignment procedure are described into the Terms of Applicability available in Resources section. In particular, WorldView-1 offers archive and tasking panchromatic products up to 0.50 m GSD resolution. Band Combination Data Processing Level Resolution Panchromatic Standard(2A)/View Ready STANDARD (OR2A) 50 cm, 30 cm HD View Ready Stereo 50 cm Map-Ready (Ortho) 1:12.000 Orthorectified 50 cm, 30 cm HD Native 50 cm resolution products are processed with MAXAR HD Technology to generate the 30 cm HD products: the initial special resolution (GSD) is unchanged but the HD technique increases the number of pixels and improves the visual clarity achieving aesthetically refined imagery with precise edges and well reconstructed details. As per ESA policy, very high-resolution imagery of conflict areas cannot be provided.

PROBA-V QWG meeting 12
The main discussion points for the QWG meeting #12 are recalled: 1. Mission Status: the operational phase was discontinued on 30 June 2020 to limit the impact of the orbital drift and the new experimental phase started on 1st July 2020 with focus on acquiring data over Africa and Europe together with ad-hoc acquisition campaigns. Flight and Ground Segment overall performances are excellent with no sign of degradation.

PROBA-V QWG meeting 13
The status of the mission was recalled: Experimental Phase is running since July 2020 with the perspective to prepare the ground for the launch and exploitation of PV-CC mission. The latest delay in the schedule of the PV-CC launch (currently Q1/Q2 2022) changed the approach for exploitation, notably owing to the degrading Proba-V illumination conditions at the time of the launch. On the processing side, the main priority is to finalize the verification phase for the C2 and start the full mission reprocessing.
