TerraStar Beam IOR Maintenance Notification

28 September 2023


There is a period of planned maintenance scheduled for Thursday 28th of September between 10:00 – 10:30 UTC temporarily affecting the TerraStar service availability on the IOR beam. Customers can expect a 15-minute service outage during the 30-minute maintenance period.

The maintenance is required to move IOR services to INMARSAT’S next-generation I-6F1 satellite. This new satellite is at 83.5E which will bring additional redundancy in the Asia-Pacific region. Upon completion of this maintenance, all TerraStar services on the IOR beam will be provided from the new I-6F1 satellite at the new location shown in red in the image below.

Refer to the mitigation section below for information on how to ensure seamless TerraStar, performance during this outage.

IP Delivery for Corrections:

All TerraStar-L & TerraStar-C PRO subscriptions include IP delivery. Using an internet-connected device (such as a modem or PC), a user can feed TerraStar corrections directly to the receiver without the need for an L-band connection or as a redundant method of delivery in addition to an L-band.

More information on IP delivery is available here: IP Delivery for Global TerraStar Corrections
