It is an augmentation system ( similar to WAAS in the U.S. ) supposed to give you meter precision . Initially planned for 2009 , now 2020 for aviation if I am correct. But by coincidence I am going to a meeting with normally them in it tomorrow . I will ask their current status .
The "etc." . In my earlier post was referring to the various augmentation systems avail or planned , including fixed ones , to allow precision APP .
