Thus the gyro package serves as a rigid angular spacereference in the same manner as the stars appear in a stellar navigator.
这样，陀螺组合件用来作为稳定的空间度基准正如在星座导航器中的星座一样。

Based on these features, an algorithm to extract fruits object from images, which is based on the approach of color spacereference list, was put forward.
In this paper, various correlative GPS spacereference frames in GPS measurement field and the principle of GPS signal constitution are introduced first.
