Hexagon | NovAtel's marine-grade GPS-713 antennas offer high-precision multi-constellation and multi-frequency GNSS tracking with a highly stable phase center, providing the functionality of choke ring designs without the additional size and weight. Providing enhanced Inmarsat interference rejection, they are ideal for installation in the presence of high-powered Inmarsat transmitters typically found on marine vessels.
The rugged antennas are housed in a durable waterproof enclosure, and are designed to MIL-STD-810G specifications for vibration, corrosive environments and salt fog, as well as IEC 60945 specifications for maritime navigation equipment and EU RoHS directives.
Both the GPS-713-GGG-N and GPS-713-GGGL-N models receive L1/L2/L5 GPS, L1/L2/L3 GLONASS, B1/B2a/B2b/B2l BeiDou and E1/E5a/b Galileo frequencies. The GPS-713-GGGL-N also supports L-Band from 1525 to 1560 MHz.
