In addition to the purchase of the satellite antenna and any optional mounts, you must pay for a line rental and add some credits on your account. One credit is used each time you transmit information to the YS6 via satellite (e.g. boat status request, settings change) or the YS6 sends you a message via satellite, such as GPS location or an alert. One credit costs approx. £0.10.
You need also to purchase a pair of radio modems to make the connection between the central unit and the satellite antenna wireless. Note these charges only apply for satellite communication. Communication via 3G/4G is free for the first 2 years and £50 (+VAT) / year thereafter.
