A Global Positioning System (GPS) unit is a device that helps someone locate, navigate, or track something. For the receiver of the unit to function at its best, it needs a GPS antenna. The 24 satellites that transmit to GPS systems, give a code that is pulled out by the GPS antenna. The GPS antenna then matches the code to measure speed and travel. The atomic clocks of the satellites are then synchronized precisely with the GPS antenna.

A GPS antenna plays a major role in the function and accuracy of a GPS unit. With more satellites in view of your GPS system, the less errors or dropouts that could occur. When a GPS antenna is in use, the more signal bars your system will produce. You will be able to get your unit to work virtually anywhere when using a GPS antenna. From dense tree cover, cave tunnels, or any weather condition, a GPS antenna will help your GPS system find the location you are looking for.

There are many GPS antennas out there on the market. They come with many different features that can meet your needs. GPS antennas may come weather proof, LNA powered, compatible with most all GPS receivers, and with a sturdy magnet able to attach to a magnetic surface. The voltage range for a GPS antenna can give input up to 5.5 VDC and they have a great out-of-band signal rejection. There are low noise figures as low as 0.8 dB, allowing your GPS antenna to provide an accurate signal and advanced acquisition times, with little to no outages.
