低纬子午环绝对测定仪器瞬时方位差方法的改进(Ⅱ)

The Improvement of Determination of the Instantaneous Azimuth Error by Lower Latitude Meridian Circle (LLMC) (Ⅱ)

在导出低纬子午环测定一颗星过卯酉、子午圈的记录时刻与瞬时方位差关系式的基础上，结合仪器在卯酉圈测定星对天顶距的方法［１］，提出了既可以绝对测定瞬时方位差。

In this paper, an equation for the recording time of a star passing through the prime vertical and the meridian, and the instantaneous azimuth errors are derived. By using the method in paper(Ⅰ), it is proposed that both instantaneous azimuth errors and the positional errors are absolutely determined simultaneously.
