Mitigation:

Automatic Beam Selection:

To ensure a seamless transition to the next available beam, it is recommended to set beam selection to automatic. The command for this is:

ASSIGNLBANDBEAM AUTO

Users that have manually assigned their receiver to track 143.5E are recommended to switch to automatic beam selection.

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 L-band.

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