Survey Antenna – External Measuring Antenna

Category:

The measurement antenna structure is sophisticated and finely crafted, serving as an external antenna for various modular surveying devices. The system’s antennas cover a variety of frequency points, including single-system single-frequency, single-system dual-frequency, dual-system quadruple-frequency, triple-system sextuple-frequency, triple-system septuple-frequency, and full-frequency, meeting the current demand for multi-system compatibility and high-precision measurement in GNSS surveying equipment. It is widely used in fields such as land surveying, marine measurement, geological deformation monitoring, micro-displacement monitoring, precision positioning, mobile mapping, large-scale engineering machinery control, and precision agriculture.

 

APPLICATION

  1. The antenna employs a multi-feedpoint design, achieving alignment of the phase center with the geometric center to minimize the impact of antenna-induced measurement errors.
  2. With high gain and a wide directional beamwidth, the antenna ensures the reception of satellite signals at low elevation angles. This feature allows the receiver to maintain normal signal reception even in environments with significant obstructions.
  3. Equipped with anti-multipath choke plates, the antenna reduces the impact of satellite signal multipath effects on the measurement accuracy of the receiver.
  4. The waterproof and UV-resistant outer cover provides protection for the antenna during prolonged outdoor use, ensuring its durability and functionality in the field.
