7.3.3. Aviation<br />

Satellite navigation has been used in aviation ever since the GPS system was<br />

first developed. Pilots can use satellite navigation in various phases of the flight,<br />

from taxiing, through takeoff, flight and landing, which is particularly important<br />

in difficult weather conditions. The growing congestion in airports and on most<br />

busy routes is becoming an increasing problem in air transport. As a result,<br />

traffic management gains importance and it would be hard to imagine it<br />

without satellite positioning of airplanes. Moreover, in congested airports<br />

satellite navigation can improve ground operations.<br />

Thanks to GPS devices (or other satellite positioning systems) it is possible to<br />

provide traffic controllers with precise and up-to-date information about the<br />

bearings, the speed or the heading, especially in those areas where ground infrastructure<br />

is not sufficiently equipped in radar and communications devices 9 .<br />

The overriding goal is to improve safety in commercial flights. But satellite navigation<br />

can also be applied in recreational or sports flights of balloons, gliders etc.<br />

Another specific area of application for satellite devices in aviation is their<br />

installation in SAR and ambulance helicopters which, by their very nature, frequently<br />

take part in rescue operation in bad weather or in otherwise difficult<br />

conditions. Thanks to such application, the safety of these helicopters can be<br />

greatly improved.<br />

7.3.4. Maritime and inland water transport<br />

Initially, the civilian application of satellite navigation was only limited to<br />

maritime transport. This was due to the considerable size of the devices, both<br />

the terminals and the satellite aerials. The fundamental application in this mode<br />

of transport is supporting open sea navigation, in order to improve safety at sea<br />

and prevent collisions. This is true for both cargo and passenger fleet, as well as<br />

tourist cruises, for instance in sailboats.<br />

Satellite navigation also improves operations in seaports, especially in bad<br />

weather conditions. This is also true for inland waterways, especially in difficult<br />

or narrow sections, in case of congestion or bad weather. Moreover, wherever<br />
