Problems solved by technology
Since the chassis of 5GAAU is generally made of a metal rear cover and a plastic front cover, if the satellite navigation positioning antenna is installed inside the AAU chassis, the antenna cannot effectively receive satellite signals due to the metal cover. thus affecting the measurement accuracy
In addition, the application of the sum-difference beam method requires the installation of four independent omnidirectional satellite navigation and positioning antennas, which increases the complexity of the system

The invention discloses a directional device of an active antenna unit, which relates to the field of communication equipment. The directional device is built-in and installed in a chassis of the active antenna unit, and includes: a first directional antenna for receiving satellite signals; The second directional antenna is separately installed in the chassis, and half of it is blocked by the metal part of the chassis, forming a half-sky blocking effect for receiving satellite signals; the first satellite positioning module and the second satellite positioning module respectively process the first directional antenna and the satellite signals received by the second directional antenna to obtain the statistical directions of the satellite vanishing zones of the first directional antenna and the second directional antenna; the dual-antenna differential directional module processes the data of the first satellite positioning module and the second satellite positioning module, Realize dual antenna differential orientation of active antenna units. The invention also discloses an orientation method of the active antenna unit. The invention effectively utilizes the metal shielding effect of the active antenna unit chassis, and improves the orientation accuracy.
Description
technical field [0001] The invention relates to the field of communication equipment, in particular to an orientation device, an orientation method and an application of an active antenna unit. Background technique [0002] A smart antenna refers to an antenna that has the ability to perceive the working parameters of the antenna. Using the sensing ability of the smart antenna, the operation and maintenance system can remotely understand the working status of the antenna, and promptly alarm when the parameters of the smart antenna change, reminding the operation and maintenance personnel to maintain, thereby greatly improving Operation and maintenance efficiency, reduce operation and maintenance costs, and reduce invalid operation and maintenance caused by blindness. Therefore, building an industrial parameter measurement device into a 5G Active Antenna Unit (AAU) is one of the future development directions of smart antennas. As an orientation device to detect the direction...
