angular accuracy

基本解释

Indexing heads, which provide high-accuracy angular standard, have been widely used in machining.
分度头是机械加工中一种常见的测量设备，主要用于提供高精度的角度基准。
By a large number of step experiments, the angular accuracy can reach 0.2". Therefore, the validity and rationality of the proposed method is well confirmed."
通过实际测量实验，测得的测角精度不高于0.2″，证明了该地面测量方法的有效性和合理性。
Applications show that the method effectively increases orbit determination accuracy at low angular measurement accuracy and high ranging and range rate measurement accuracy.
工程实践应用表明，在测角精度比较低而测距、测速精度相对高的情况下，该方法可有效地提高轨道确定的精度。
