Hemisphere GNSS Announces New Survey-grade GNSS Antennas

Hemisphere has launched two low-profile, multipurpose antennas that will arguably exceed expectations in all GNSS applications. With innovative 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, the company announced.

The A25 and A45 have been designed to support millimetre 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.

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

The ruggedised housing utilised by both antennas is made of an aluminium base that has been pretreated for the marine environment and will withstand salt, fog, and spray. The antennas easily pass the two-metre pole drop test.

The A25 is a multi-GNSS precision antenna, ideal 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, ideal for a variety of applications including surveying, RTK positioning and navigation, precision guidance and machine control.

Both antennas were featured by Hemisphere GNSS at Intergeo 2014 in Berlin, Germany from 7-9 October 2014 at stand C2.007. For more information about Hemisphere GNSS’ antennas and other products, see www.hgnss.com/Products-Solutions.
