Choke ring-like performance
The GPS-700 series, including the single frequency GPS-701 and the dual frequency GPS-702, takes advantage of Pinwheel™ technology to provide exceptional multipath rejection. With a gain roll off to the horizon of 13 dB for the L1 signal and 11 dB for L2, the GPS-700 provides performance comparable to that offered by a typical choke ring and antenna combination. Signals arriving from low elevation angles are attenuated, virtually eliminating position errors due to troublesome signal reflections.
Stable phase center
For added reliability, the antenna's phase center remains constant as the azimuth and elevation angle of satellites change. With signal reception unaffected by the rotation of the antenna or satellite elevation, placement and installation of the GPS-700 can be completed with ease. In addition, the phase center is in the same location for both the L1 and L2 signals. This, combined with minimal phase center variation between individual antennas, makes the GPS-700 ideal for baselines of any length.
Rugged and lightweight
While providing equivalent multipath reduction, the GPS-700 is significantly smaller, lighter, and more economical than a combined choke ring and antenna solution. Both L1 and L1/L2 models share the same enclosure and mounting system for quick conversion from single- to dual-frequency operation. In addition, the GPS700 is waterproof to IEC 60529 IPX7 and meets the MIL-STD-810F specification for vibration and salt spray, resulting in an antenna suited to diverse applications, including marine environments, precision agriculture, and machine control.
