Description

This antenna is a comprehensive external surveying solution designed to encompass GPS L1/L2, BD B1/B2/B3, GLONASS L1/L2, and Galileo E1/E2/E5a/E5b/E6 frequencies. It effectively fulfils the requirements for compatibility across multiple systems and facilitates high-precision surveying tasks using GNSS equipment. Its versatile applications span various domains such as Geodesy and mapping, Marine surveying, geological deformation monitoring, micro-displacement tracking, precise positioning, mobile mapping, controlling large-scale engineering machinery, and enhancing agricultural practices.

1. The antenna part adopts a multi-feed point design and a completely symmetrical antenna structure to realize the coincidence of the phase center and the geometric center and reduce the influence of the antenna on the measurement error.

2. The antenna gain is high, the direction pattern beam is wide , with good signal reception at the low elevation, to ensure that in some more serious occlusion occasions can still receive the satellite signal normally.

3. The low-noise amplifier adopts pre-filtering scheme to effectively suppress out-of-band interference and improve the reliability of the system.

4. The power supply circuit adopts lightning protection design, which can effectively protect the low noise amplifier and ensure the antenna can still work normally in the harsh outdoor environment.

5. Built-in voltage regulator circuit, the antenna can work normally in a wide input voltage range.
