Well the time has come to bite the bullet and start the process of registration to receive the vast quantity of data being transmitted from the EUMETSat service, the organisation being based in Darmstadt, Germany.
The data is free to receive but, as this operation is costing hundreds of millions of pounds to run they are understandably reluctant to have their very valuable data wafting around to all and sundry without some kind of control. Some of the data is free for all but others require a license and you must agree to certain conditions concerning your usage of the final product. Not unreasonable I think.
The first thing to do is to get yourself to the EUMETSat EO Portal where you can start the registration process by creating an account https://eoportal.eumetsat.int/userMgmt/login.faces . You are not committing to anything by creating an account and you can come back and add services and licenses at a later date.
The amount of data which flows down seems to be staggering and , before you start filling in forms, please go to the GEO website and have a nose round to get a feel of what is available, what you need and what is going to clog your hard drive and bring your PC to its knees.
Before filling in the licence agreement, go here and read the guide to filling in the registration documents. Without it you will be completely lost.
