Harxon recently has launched D-Helix Antenna, a high performance, full constellation GNSS antenna for UAV applications.

The industrial innovative D-Helix Antenna is capable of superior tracking signals from GPS L1/L2/L5, GLONASS G1/G2/G3, BDS B1/B2/B3, Galileo E5a/E5b/E6/E1, and Inmarsat L band. The 4dBi high gain and wide beam width ensure a better signal receiving performance of satellite at low elevation angle, which is aiming to increase system positioning accuracy and data validity. The innovative quadrifilar helix design provides a stable phase centre of D-Helix Antenna. The low noise figure enhances transmission interference reduction and improves the signal quality. Also it provides exceptional coverage inside buildings, vehicles or other areas where weak signals and signal reflection occur.

D-Helix Antenna’s ruggedized design includes IP-65 protection from dust and water, as well as a standard SMA male connector for easy integration. The low wind-resistance design in a 45g small and lightweight form factor is ideal for UAV positioning and navigation.

Harxon D-Helix Antenna can be used in various UAV applications, for example plant protection with shelterbelts, high precision UAV power patrol, GIS surveying, and intelligent driving. It provides the centimetre-level positioning accuracy for a stable flightpath and prevents air turbulence, to enable a reliable positioning, height setting and heading information.
