GPS-701

The GPS-701 is a rugged, lightweight antenna designed for superior L1 performance in a variety of applications. It incorporates NovAtel’s patented Pinwheel™ technology to provide superior multipath rejection equivalent to that offered by a combined choke ring and antenna solution. However, at just 480 grams and with a diameter of 185 millimeters, the GPS-701 is significantly smaller, lighter, and more economical than a choke ring antenna. Built to withstand severe weather
and hostile environments, the antenna is waterproof to IEC 60529 IPX7 and meets the MIL-STD-810F specification for vibration and salt spray. The GPS-701 also features a highly stable phase center that remains constant as the azimuth and elevation of satellites change, offering flexibility in antenna placement and installation.
