Product Description

Product description                                               GNSS FULL-Band UAV Antenna---GNSS-B78L-TK

     This antenna can simultaneously receive signals from the GPS L1/L2/L5, GLONASS G1/G2, and BeiDou B1/B2/B3 frequency bands. It is compatible with mainstream boards both domestically and internationally, and can be paired with high-precision dual-frequency positioning chips and boards to achieve sub-meter level positioning accuracy with plug-and-play functionality. When used with ground-based auxiliary stations, it supports RTK for millimeter-level high-precision positioning. It is widely used in aerospace, precision agriculture, vehicle positioning, and unmanned driving applications that require high-precision GNSS positioning, particularly in the field of high-precision positioning and orientation for drones.
The antenna has the following characteristics:

• The antenna has the characteristics of high vertex gain, wide beam pattern and wide angle circular polarization, which can receive low elevation angle signals well and ensure that the satellite can be received normally in some places with serious occlusion.
• The antenna adopts multi-feed point design scheme to ensure that the phase center coincides with the geometric center and reduce the influence of the antenna on measurement error. The phase center deviation of the antenna is at the millimeter level;
• The antenna has a unique lightning protection and anti-static circuit design, with overvoltage protection circuit, using high performance out-of-band filter design, to ensure that the antenna can work normally in all kinds of harsh environment.
• The antenna cover is made of UV resistant high strength ABS material, and the waterproof performance is IP67. The antenna base is designed with titanium aluminum material to effectively reduce the weight of the antenna.
• The low noise amplification part adopts a two-stage filtering scheme, which filters the received signal first and then amplifies it. It can effectively suppress strong interference signals outside the band, avoid causing amplifier saturation and improve the reliability of the system.
