UAV
Unmanned aerial vehicle (UAV) is a kind of unmanned aerial vehicle operated by radio remote control equipment and its own program control device. With the gradual maturity of UAV research and development technology, manufacturing costs are greatly reduced, and drones are gradually popularized in the market, which has immeasurable benefits in improving life production efficiency, reducing workload and production costs, improving accuracy and operational safety. At present, it has been widely used in agricultural plant protection, power inspection, express transportation, police law enforcement, geological exploration, environmental monitoring, forest fire prevention and film and television aerial photography and other fields.
The role of GNSS
The UAV positioning antenna is equivalent to the "eye" of the UAV. The high-precision positioning technology includes compatibility with GPS, BDS, GLONASS, GALILEO and satellite-based augmentation systems, antenna beamforming, providing multi-system and multi-azimuth strong satellite signals to provide centimeter-level (its to millimeter level) positioning accuracy. At the same time, it can effectively deal with the interference between systems in the working environment of the UAV in the multi-communication frequency band, so that the UAV can always maintain stability during flight, and provide high safety during automatic cruise, which can effectively avoid the "explosion" of the UAV and ensure the reliability and controllability of the UAV in the work.
