Satellite service provider Inmarsat requested Fugro to move our DGNSS services from 1539 MHz to 1545-46 MHz.
As a result Fugro's AORW augmentation service (covering the Americas) was replaced with a close-to-identical service called WASAT at 1500 UTC on 31 December 2020.
Please view the technical bulletin.
