A radio beacon which transmits nondirectional signals whereby the pilot can use the ADF to determine his bearing to or from the station. 发射无方向信号的无线电信标台。据此飞行员能够用自动定向仪(ADF)确定他的背台或向台方位。
TACAN is a short-range radio navigation system, designed to provide the bearing and distance information for the flying objects. 塔康是近程无线电导航系统,主要为空中飞行目标提供方位和斜距导航信息。
The geometric parameters measured in long range ρ-θ radio navigation system are great circle bearing and great circle path ρ. 在远程ρ&θ无线电导航系统中,被测几何参数为大圆方位角θ和大圆距离ρ。
