In astrometry , the term is applied to the difference between the observed position ( or magnitude ) of a reference star and the position ( or magnitude ) listed in the star catalog 在天文上，本术语指的是观测的参考星的位置（或星等）与星表上的该星的位置（或星等）的差值。

Additional objects , or asteroids not found by the moving object detection algorithm , may be measured by clicking on them , similar to the way objects have been measured in the tutorial i ( basic astrometry ) 其他目标或没有被软件认可发现的小行星，你也许可以用指南1中的方法来测量它们。

With the development of space geodesy techniques ( vlbi , llr , slr and gps , et al . ) , the application of classical geodesy and astrometry became less and less in application , but it is indispensability technique in absolute orientation of geodesy , launch of mid and long - distance arms , and in other scientific domains 随着空间大地测量技术（ vlbi 、 llr 、 slr和gps等）的发展，虽然天文测量在应用上有所减少，但在大地测量的绝对定位和中远程武器的发射等领域中仍然是不可替代的技术。
