Satellite service provider Inmarsat requested Fugro to move our DGNSS services from 1539 MHz to 1545-46 MHz.
As a result Fugro's ASAT augmentation service (covering the Americas) was replaced with a close-to-identical service called AMSAT at 1500 UTC on 30 December 2020.
It is important to verify that automatic switchover has occurred, and for users whose equipment requires manual configuration, to make the changes manually.
