Support GPS/GLONASS/BEIDOU/GALILEO and QZSS system

MA-900 supporting ultra precise applications such as automatic driving, high-rise building urban areas with poor signals, high precision requirements from agriculture and construction applications and land and marine applications.


Overview:
MA-900 integrates high performance GNSS 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 3~15V DC input power. MA-900 receives all existing public GNSS signals, including GPS, GLONASS, Galileo and BeiDou as well as GPS L2C/L5, QZSS L6, GLONASS G2 and BD2 B2/B3, which provides better positioning accuracy for a variety of GNSS applications such as AVL, vehicle navigation, aviation, and military.

Features:

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

Applications:

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