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 an orientation device for an active antenna unit and relates to the field of communication devices. The orientation device is built in a case of the active antenna unit, and comprises: a first second directional antenna and a second directional antenna for receiving satellite signals, wherein the first and second directional antennas are separately installed in the case anda half of each of the first and second directional antennas is shielded by the metal portion of the case to form a half shielding effect of the received satellite signals; a first satellite positioning module and a second satellite positioning module for processing the satellite signals received by the first directional antenna and the second directional antenna respectively, and obtaining the statistical direction of the satellite disappearing zone of the first directional antenna and the second directional antenna; and a dual-antenna differential orientation module for processing the data of the first satellite positioning module and the second satellite positioning module and achieving the dual-antenna differential orientation of the active antenna unit. The invention also discloses anorientation method for the active antenna unit. The orientation device effectively utilizes the metal shielding effect of the case of the active antenna unit and improves the orientation precision.
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...
