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 ìpatchî antenna. It is usually round or approximately square, and its dimensions make it sensitive to the GPS frequency being tracked. When a GPS receiver/antenna combination is tracking satellites and making code and carrier phase measurements, the actual points in space between which those measurements are taken are the instantaneous phase centers of the GPS satellite and GPS receiver antennas. This is a function of the apparent azimuth and elevation of the satellite being tracked, and the way that the antenna is fed, that is, how it is electrically connected to the rest of the circuit. Because multiple sate.
