Si-Tex GPK-10 GPS Sensor
Some skippers might be surprised to learn that the GPS portion of their plotter may be entirely housed in its antenna. Si-Tex is one of the first to separately market such a self-contained marine unit, ready to drive almost any position-desiring devices via the NMEA 0183 protocol. The $299, waterproof GPK-10 is only three inches high and four inches in diameter and comes with a 50-foot cable carrying power and sensor wires. The unit has WAAS correction technology usually accurate to about nine feet and is one of the first able to track 18 satellites simultaneously. While it is not (yet) possible to see that many satellites at once, this capability supposedly helps to speed up fix acquisitions.
