This is an active, multi-frequency GNSS antenna for high-accuracy positioning. It receives GPS L1/L2/L5, GLONASS G1/G2/G3, Galileo E1/E5a/E5b, BeiDou B1I/B2I/B1C/B2a/B2b, SBAS L1/L5, QZSS L1/L2/L5 and IRNSS I5. It is made for applications that need more accuracy than an L1-only antenna can give, such as GIS and RTK.
The antenna uses a quadrifilar helix structure. This gives it good pattern control and polarization purity, and high efficiency in a small body. It is ground plane independent. The housing has an integrated SMA connector, an IP67 rating, automotive grade electronics and an O-ring.
It needs little integration effort and can be used to retrofit existing products.
