Hemisphere GNSS has announced two low profile, multipurpose antennas that it says will exceed expectations in all GNSS applications. With unique filtering patterns and precise attention paid to mitigation of multipath and interference, the A25 and A45 antennas complement all GNSS products, from L1 GPS to multi-frequency, multi-constellation.

Both antennas are being featured at the InterGeo 2014 Conference and Trade Show in Berlin this week, at stand C2.007.

The A25 and A45 have been designed to support millimeter accuracy for land and marine applications. Both antennas support present and future GNSS signals, including GPS, GLONASS, BeiDou, QZSS, and Galileo. The A25 supports the previously mentioned signals at a single-frequency level, while the A45 supports these signals at a multi-frequency level.

“We’ve designed these antennas to excel in challenging environments such as near buildings or under foliage,” said Lyle Geck, senior manager of product marketing at Hemisphere GNSS. “They have superior multipath mitigation, stable phase centers and strong SNR’s, even at low elevations.”

The ruggedized housing used by both antennas is made of an aluminum base that has been pretreated for the marine environment and will withstand salt, fog, and spray. The antennas pass the two-meter pole drop test.

The A25 is a multi-GNSS precision antenna, designed for a variety of applications including GIS, single-frequency RTK positioning and navigation, and precision guidance. The A45 is a survey-grade, multi-GNSS precision antenna for a variety of applications including surveying, RTK positioning and navigation, precision guidance, and machine control.
