AX3703 is a miniature, light-weight, multi-frequency GNSS antenna, which receives GPS L1/L2, GLONASS G1/G2 and BDS B1/B2/B3 frequencies. Its outstanding performance in dynamic scenario and its light-weight are particularly suitable for drone and other moving platforms. Its rugged design makes it work well even in the most harsh environments.

Key Features:

  • Supports multi-constellation and multi- frequency
    • GPS L1/L2, GLONASS G1/G2 and BDS B1/B2/B3
  • Radom reduces the impact of temperature variation
  • Rugged design supports complex working environment
  • Super compact design with 87mm diameter (including ground plane)
  • Lightning proof design protects antenna in harsh weather condition
  • High gain, good low elevation roundness and wide-angle roundness polarization
  • Multipath suppression technique improves performance in challenging environment
  • Multiple feed design stabilizes carrier phase center and minimizes influence to measurement error
