描述

  • The B4QB2GGGB is a four-system full-frequency external handheld antenna covering BDSB1/B2/B3, GPS L1/L2/L5/L-Band, GLONASS L1/L2, GALILEO E1/E5a/E5b
  • Low height for easy integration: The overall size of the antenna is Ф43.6*H40.8mm. The antenna is low and easy to design for system integration. The light weight itself can effectively reduce the weight of the drone and increase the battery life of the drone;
  • High Phase center stablility: The antenna part adopts a multi-feed point design to achieve the coincidence of the phase center and the geometric center, minimizing the impact of the antenna on the measurement error;
  • High stability: The antenna unit has high gain and wide pattern beam, ensuring the reception effect of signals at low
    elevation angles. It can still receive stars normally in some situations with severe obstruction, such as aviation equipment can also work normally when flying at an angle;
  • Wideband multi-frequency operation: The antenna bandwidth covers satellite frequency bands (BDS B1/B2/B3, GPS L1/L2/L5/L-Band, GLONASS L1/L2, GALILEO E1/E5a/E5b), which can provide multi-channel positions for drones in complex flight environments. Positioning information to ensure flight safety.

    • Application

    The B4QB2GGGB antenna can be widely used in used Surveying, mapping, navigation and dispatching and other industries, especially suitable for many applications of light drones, such as aerial photography, remote telemetry, disaster monitoring, traffic patrol, public security monitoring, etc.
