Disclosed are an antenna attitude measurement sensor and a method for antenna attitude measurement based on said sensor. The sensor comprises a solar position sensor (3), a triaxial gravitational acceleration sensor (4), a GPS module (5), a central processing unit, a power supply module, and a storage and output module. The antenna attitude measurement method comprises the following steps: a. installing an antenna attitude measurement sensor; b. acquiring the antenna's geographical location, hanging height, pitch angle γ, roll angle &thetas;, azimuth angle Φ of incident sunlight relative to the solar position sensor, and a standard time corresponding to the acquisition of Φ; c. calculating the angle of perpendicular incidence α and the angle of horizontal incidence &bgr;; d. calculating the antenna azimuth angle δ; e. storing and outputting data. The antenna attitude measurement sensor and attitude measurement method measure the antenna direction by means of utilizing sunlight in combination with other antenna-aligning measurement information, thus avoiding orientation inaccuracy caused by electromagnetic interference in the traditional magnetic-orientation method, therefore ensuring measurement-data accuracy of antenna working parameters. A reliable foundation is thus provided for the construction, maintenance and optimization of communication base station antennae. |
