This is an active, multi-band GNSS antenna for high-accuracy positioning. It receives GPS L1/L2/L5, GLONASS G1/G2/G3, Beidou B1I/B2I/B1C/B2a/B2b, Galileo E1/E5a/E5b, SBAS L1/L5, QZSS L1/L2/L5 and IRNSS I5. It is designed for applications that need more accuracy than an L1-only antenna can give.
The antenna uses a quadrifilar helix structure. This gives it pattern control, polarization purity and high efficiency in a compact body. It does not depend on a ground plane. It has an integrated SMA connector, IP67-rated automotive grade components and an O-ring.
It is made for GIS, RTK and other high-accuracy GNSS uses, and for retrofitting existing products with minimal integration effort. Power consumption is low, and phase center variation is low across azimuth, elevation and different samples.
