AR170 High-Accuracy GNSS Active Antenna

High-Accuracy GNSS Active Antenna

Model: AR170
V1.0 2017-04-07

Survey grade waterproof antenna resists unwanted signal interference, designed to support ultra-high accuracy for land and marine applications.


AR170 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. AR-170 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.


  • Substantial and environmental-resistance structure
  • Proprietary antenna design provides the flexibility to reach a range of operational goals
  • IP67 grade waterproof
  • Supports GPS, GLONASS, Galileo, and BeiDou systems
  • Multi-Constellation and Single-Frequency for faster initialization


  • Geospatial Surveys
  • AVL
  • Single frequencies RTK positioning
  • Vehicle Tracking
  • Security Surveillance
  • Precise Guidance
  • Machine Control
