These systems were designed for use in remote places and each has good coverage at sea, with Iridium providing service even in high latitudes.Īnd the hardware for these systems is relatively inexpensive. The second option for satellite internet at sea is the more robust solutions provided by Iridium, Inmarsat and Globalstar. As you can see from these maps, you are not going to travel more than a few hundred miles from shore before losing your connection. The second challenge of using a Hughesnet type system is that the satellites are geostationary, hovering at points within line of site of the continent. To compensate you will need a gyro stabilized antenna with an internal VRU that compensates not only for changes in heading, but for the pitch and roll of a vessel. While you may save money, you will run into connectivity issues as these systems are not designed to connect with a continually moving object.
An inexpensive option, and one that is used by many Americans that live far from city centers, are systems like Hughesnet or Wildblue. Once you have decided to invest in a sat system you have a few choices. So, for ocean voyages there is only one solution: satellite internet.
The remaining posts of this series will look at terrestrial based systems for accessing internet at sea but all such systems fail once your ship sails into deep water. To start our series on Breaking Free Of Corporate Internet at sea we will first take a look at VSAT technology.
