The use of advanced materials enables the Trimble Zephyr and Zephyr Geodetic antennas to be extremely compact and lightweight. Although the antenna element and low noise amplifiers used today will need to be modified in order to be compatible with the future L5 second civil frequency, the underlying design of the new Trimble Stealth Ground Plane is independent of frequency. This will make it much more effective for use with the new frequency than more conventional ground planes. The GPS antenna element is the part of an antenna that is sensitive to energy transmitted from GPS. For precise GPS surveying, this element is usually a flat piece of metal called a patch antenna. It is usually round or approximately square, and its dimensions make it sensitive to the GPS frequency being tracked. W.
