GPS DOME (see Figure 1 and 2) is a compact, light-weight GPS anti-jamming module, designed to prevent loss of position fix and time in the presence of certain types of jammer. The unit may be installed on a range of installations that rely on GPS and connects between the antenna and the GPS receiver.
Two active GPS antennas, with nominal gain of 26dB, are connected to the SMA RF connectors; the primary and auxiliary antenna inputs. The RF Output provides connection to the input of the GPS Receiver.
