overview

This antenna can simultaneously receive signals from Beidou B1/B2/B3, GPS L1/L2, GLONASS L1/L2, and GALILEO L1/E5b frequency bands. It can be perfectly matched with mainstream domestic and foreign boards and can be used in conjunction with high-precision dual frequency positioning chips and boards to achieve sub meter level positioning accuracy through plug and play; Cooperate with ground-based auxiliary stations to support RTK for obtaining millimeter level high-precision positioning. Widely used in aerospace, precision agriculture, vehicle positioning, unmanned driving and other applications, GNSS high-precision positioning is particularly suitable for the high-precision positioning and orientation field of unmanned aerial vehicles.

Antennas have the following characteristics:

Antennas have the characteristics of high vertex gain, wide beam width in directional patterns, and wide-angle circular polarization. They have good reception performance for low elevation signals, ensuring normal reception even in situations with severe occlusion;

The antenna adopts a multi feed point design scheme to ensure that the phase center coincides with the geometric center, reducing the impact of the antenna on measurement errors. The phase center deviation of the antenna is in the millimeter level;

The antenna has a unique lightning and anti-static circuit design, with an overvoltage protection circuit and a high-performance out of band filter design to ensure that the antenna can work normally in various harsh environments;

The antenna cover is made of UV resistant high-strength ABS+PC material, with a waterproof performance of IP67 and a weight of only 20g.

The low-noise amplifier adopts a two-stage filtering scheme, which can effectively suppress strong out of band interference signals and improve the reliability of the system.
