Maritime

In the Maritime Industry, several different ways of communication are used.
When a vessel is close to the coast, it communicates via VHF (very high frequency) and UHF (ultra high frequency) radio transmissions. When there is coverage cell phone communication is possible.
When the vessel is further away from the coast it communicates via VHF and MF (medium frequency)/ HF (high frequency) with other vessels. To communicate with the coast, vessels communicate via satellite because of the global coverage.

Vessels use GPS satellite tracking systems for highly accurate navigation and positioning, and for determining a vessel's precise speed and heading. The transmitter is covered with a water resistant dome. The GlobalTrack system can be combined with a PDA. For example in the Maritime Fishing Industry , the precise speeds and position of the vessel can be tracked. With this information fishing vessels can maintain trailing nets at desired depths. This contributes to a higher productivity: catch quantities can be transmitted to shore facilities to prepare for processing, sale and transport upon arrival. Besides monitoring the positioning of the vessel, two-way communication is possible.

Maritime vessels tracked on this satellite-based system, provides information such as :

• The location of a vessel can be tracked around the clock;
• In combination with your existing ERP system, not only position information can be send. Data such as arrival time (ETA), weather conditions and course changes can be received;
• Incidences of piracy can be avoided;
• Emergency messages can be sent to the coast.
