Regional Coverage

Sealink Premium can be selected with regional or global Ku-band coverage, or global C-band. Marlink operates the most extensive VSAT network in the market with several overlapping beams in most regions. This means vessels will rarely (if ever) be outside of Ku-band coverage, and in most regions are served by two or more Ku-band beams, providing robust satellite resiliency.
