Non-scientific measuring instruments

The satellite also carries a Canadian instrument known as AIS (Automatic Identification System) - as an experimental payload for ship surveillance in VHF band to derive position, speed and other information about ships.

DATA COLLECTIONS

ESA is offering, for scientific research and application development, access to archive and new tasking data from ResourceSat-2 data upon submission and acceptance of a project proposal. These products are available as part of the GAF Indian Satellite Imagery products.

ESA will support as many high-quality and innovative projects as possible within the quota limit available, therefore only a limited amount of products can be made available to each project.

Following collection is available:
