室内GPS利用测量的水平角和垂直角来定位,其测角误差直接影响到系统的综合测量误差,结合室内GPS的测角误差,提出了室内GPS角度校准装置的技术要求,并分别对俯仰角校准和水平角校准所需准确度进行估计,最终利用新型同轴调整装置结合精密转台和竖轴激光导轨研制了一套室内GPS发射器角度校准装置,试验数据表明该装置的俯仰角测量误差小于0.9″,水平角测量误差小于1.6″,解决了室内GPS发射器水平角和俯仰角的校准问题。

The comprehensive measuring accuracy of indoor GPS system is mainly influenced by the measuring errors of individual angular measurements with a triangulation network, and the first step in assessing the accuracy of the system is to determine the uncertainties of an indi-vidual horizontal angle and vertical angle. In this paper, with the consideration of angle measuring accuracy of GPS, the precision of angle cali-bration devices was calculated and analyzed. An angle calibration device for indoor GPS transmitters was developed with the integration of a preci-sion turntable, a laser coaxial adjustment device and a vertical axis. Experiments were carried out and results show that vertical angle measure-ment error is 0. 9″and horizontal angle measurement error is 1. 6″, which satisfy the technical requirements.
