Objectives of the test bed
• Perform a trial from a practical point of view.
• Tracking (a) vessel/vessels during voyage, and perform
testing on seamless and continuous communication
ship to shore and shore to ship in the Arctic region
• Detect gaps in the satellite availability
• Detect gaps in the general communication availability
(NA)
• Test communication capacity (NA)

Norwegian Coastal Express
• The Norwegian Coastal
Express (Hurtigruten) represent
a fleet of Norwegian passenger and freight liners with daily
sailings along Norway's western
and northern coast.
• The coastal steamer MS FRAM
sails the Artic and Antarctic as a
regular cruise ship.

SAT Solution
• Very small aperture terminal (VSAT)
• Typically from 56 kbit/s up to 4 Mbit/s.
• VSAT access satellite(s) in geosynchronous orbit to relay
data.
• FRAM uses:
– Ku band
– C band
– ++
• Smartbox

Preliminary Conclusions with reservations
• Lack of continuous communication in the arctic area.
• Some areas less than 50% availability* (24h)
• Less availability in the north than further south*
• Weather/Sea state, partly taken into consideration
• Terrain conditions, not taken into consideration
• System stability/antennas onboard could an issue
• More studies needs to be done (SAT constellation, antenna
installation, areas, availability, capacity etc)
*in test bed area
