Features:
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.
