| Abstract | 我们根据乌鲁木齐ＶＬＢＩ站的１９５４北京座标系的座标（ｘ，ｙ），利用Ｇａｕｓｓ的反算公式，计算出乌鲁木齐ＶＬＢＩ站的大地座标（Ｌ，Ｂ），并通过有关公式得到了天文座标（λ，ψ）值，然后根据测站的天文座标计算北极星大距时的位置，再由北极星大距时的位置找到天极的方向，最后解决了大型天文测量设备的定向问题。 |
| Other Abstract | The geodetic coordinates(L,B) of Urumchi VLBI station was calculated with the method of Gauss coordinate translated according to the coordinates(x,y) of Urumchi VLBI station of Beijing coordinate system, 1954: then, the values of astronomical coordinates(A,p) was obtained by related formulae, the position of the Polaris at elongation was calculated by the coordinates; the direction of the north Pole was found out according to the position: finaly the orientational problem of according to the position; finaly the orientational problem of the large astronomical observing equipment (the null point position of the azimuth about the radio telescope) was solved. The coordinates which we calculated was used in the installation and modulation of the 25m radio telescope, and the international joint observations. Recently, the ccordinates was compared with which obtained by GPS, The results are satisfactory. |
