摘　　要：针对无线电导航信标台校验的实现难点,提出了以GPS RTK为导航定位基准,以综合导航接收机为导航信号处理平台的校验方案。研究了不同导航坐标系下的校验参量统一问题,得到了极坐标导航定位体制的斜距和相对磁方位角校验方法,以及时间基准波束扫描体制的方位角、仰角和反方位角的校验方法。For the realization of general navigation calibration,a general navigation receiver based on navigation position standard with the help of GPS RTK is proposed.The calibration parameters under different navigation coordination systems are transformed to the same system,which makes these parameters be compared in a proper way.Under these conditions,the ranging and the relative magnetism azimuth angle of the polar coordination are calibrated.And the azimuth angle,elevation angle and the reversal azimuth angle of Time Reference Beam Scanning navigation system are also calibrated.
