Harxon has released the multi-constellation D-Helix Antenna at the 2017 Intergeo trade show, held Sept. 26-28 in Berlin, Germany. The Harxon booth is located at Hall 4.1, Stand C4.013. The industrial, innovative D-Helix Antenna is capable of superior tracking of signals from GPS L1/L2 L-Band, GLONASS L1/L2, BDS B1/B2/B3 and Galileo. The innovative quadrifilar helix antenna design of low wind-resistance is ideal for UAV positioning and navigation. The increased antenna gain and beamwidth ensure a better signal receiving performance of satellite at low elevation angle. The low noise figure enhanced transmission interference reduction and improve the signal quality. The D-Helix antenna can be used in UAV patrol, UAV plant protection, unmanned patrol robot and unmanned surveying vessel. According to the company, it provides the centimeter-level positioning accuracy for a stable flightpath and prevents air turbulence, to enable a reliable positioning, height setting and heading information. The antenna has been recognized by many industry experts and received inquiries from potential partners at the first launch day. Other showcased products from the Harxon GNSS family include its survey antenna, rover radio, frequency hopping modules, smart antenna and H-RTK, are also appropriate for the fields of surveying and mapping, precision agriculture and UAVs.
