Satellite service provider Inmarsat requested Fugro to move our DGNSS services from 1539 MHz to 1545-46 MHz.
As a result Fugro's AUSAT augmentation service (covering eastern Asia and the Western Pacific) will be replaced with a close-to-identical service called OCSAT on 15 November 2021.
The changeover period begins on 4 October 2021, providing a six-week period of dual operation.
It is important to verify that automatic switchover has occurred, and for users whose equipment requires manual configuration, to make the changes manually.
Please view the technical bulletin.
