GL-111
integrates high performance GPS ceramic patch antenna and unique filtering features with innovative proprietary circuit design and advanced double filters, which reduce interference from out-of-band signals. The design of the ceramic antenna element also helps to reduce the multipath effect. With especially-designed rugged/IP67 water ingress enclosure, the GNSS antenna is suitable for installing in harsh environment. The high-performance active antenna is compatible with most GPS/GNSS receivers with 3~5V DC input power. GL-111 receives all existing public GNSS signals, including GPS, GLONASS, Galileo and BeiDou, which provides better positioning accuracy for a variety of GNSS applications such as AVL, vehicle navigation, aviation, and military.
