Abstract
In the second phase of the Tianlai project, a large parabolic cylindrical antenna array with a size of 100 m × 100 m will be built. Three kinds of pitching schemes for the cylindrical antenna were developed. In order to measure the elevation angle in different pitching schemes universally, the GNSS-based (Global Navigation Satellite System based) elevation-angle-measurement method is proposed in this paper. First of all, the geometrical and physical principles of the new measurement method are analyzed. Then, five kinds of measurement system layouts are designed and compared from high accuracy, low-power consumption, low cost, anti-interference, and high reliability. Next, an experimental scheme of the GNSS-based elevation-angle-measurement method is developed, and the experiment is carried out. Finally, the error of the elevation angle measured by experiment is analyzed. The experimental result shows that the new method can meet the precision requirements of elevation angle measurement for the cylindrical antenna in the second phase of the Tianlai project. This paper also provides a reference for the elevation angle measurement of other large cylindrical antennas.
