GPS
|
| Position information for the vessel, and thus all the environmental measurements, is provided by a Garmin, Int. (GPS 17-N) Global Positioning System (GPS) sensor. The is primarily designed for marine applications. It is well adapted to harsh environments with the sensor’s antenna housed in a rugged waterproof design. It has a 12-channel receiver that allows for continuous tracking of all visible satellites. On average, the accuracy of the position given by this GPS is less than 3 meters. In addition, to providing position information for the vessel, this unit also provides a "differential" GPS capability which provides an absolute measure of the vessel's speed. Having such information is necessary in order to correct the wind speed observations for the movement of the vessel itself. The GPS sensor is installed onto a small mast on the roof of the main bridge. |
