    Abstract: An electronic navigation system is disclosed having a range calculation unit including a velocity detector which provides an error signal having a sense and magnitude corresponding to the sense and magnitude of reply pulses which are received during transceiving operations. The calculation unit also includes a counter system for up-down counting of reply pulses which indicates the quantity of valid reply pulses which have been received.

    Abstract translation: 描述了可并入Tacan空中导航组中的数字范围计算机。 计算机包括计算单元,该计算单元根据从询问和回复信号之间经过的时间的信息计算范围。 信号通过输入控制和量程门控制单元输入到计算单元。 另一个控制单元由计算单元操作,并根据之前的计算产生合成回复信号。 合成应答信号用于控制单元,以便在不存在应答信号的情况下,连续地维持计算单元的操作。 合成应答信号也被采集控制单元使用,以便以搜索或跟踪操作模式来调节系统。
