Title:
AZIMUTH MEASUREMENT DEVICE, ANTENNA, AZIMUTH MEASUREMENT SYSTEM, AND MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2017/211177
Kind Code:
A1
Abstract:
An azimuth measurement device (100), antenna (400) employing the measurement device (100), azimuth measurement system, and azimuth measurement method. The measurement device (100) comprises a sensing device (1) used to detect the geomagnetic field distribution surrounding the measurement device (100), a drive device (2), and a measurement motherboard (3). The measurement motherboard (3) outputs a control instruction to control the drive device (2) to drive the sensing device (1) to perform spiral motion, and receives and processes a geomagnetic signal detected by the sensing device (1) to perform calibration and compensation, thus removing influences of the surrounding environment of the measurement device (100) on azimuth measurement. The measurement device (100) of the present invention has the advantages of high measurement accuracy and a low cost.
