But compass sense alone cannot explain how birds navigate the ocean: after a flock traveling east is blown far south by a storm, it will assume the proper northeasterly course to compensate

说的是compass sense不能解释一个问题：为什么一群鸟往东飞，遭遇到由北向南的风暴时，它们会自己弥补一个东北的方向，从而回到自己原来的航线上

A comparison of the readings of the gyrocompass and magnetic compass shall be carried out every hour so as to maintain the fixed course of the ship and to determine and check the deviation and variation of the magnetic compass.

每小时对磁罗经和电罗经的读数进行比较，以便于保持船舶的固定航线，测定和检查磁罗经的偏差和变化。

Fluxgate sensor inducts the environment magnetic field, outputs the compass course signal to the CPU system. This signal then is transformed into digital signal. CPU processes it and then gains compass course. When use rotary mathod to measure the deviations, CPU first collects timed the compass course come from the Fluxgate sensor, then calculates automatically their deviations and the correspondent coefficients. Based on all this, CPU can calculates out the real-time magnetic course or the real-time ture course, then sents them to display on the digital displayer.

本系统采用磁通门传感器来直接敏感合成磁场，输出罗航向直流感应电压信号送A/D转换器进行转换，并经CPU计算处理得到罗航向度数值，以及利用&旋回法&测定自差时，CPU按照船舶旋回的角速度定时地采集罗航向度数值，在此基础上CPU自动地计算出各采集罗航向上的白差，再由此计算出自差系数，并实时地解算出磁航向值或真航向值，送数码显示器显示。

Only on this projection are two points on the map at correct compass course from one another.

只在这种投影之下地图上相互两点的罗盘方位才是正确的。

He forced his eyes to check the compass course and his brain to calculate an approximate position.

他强打精神察看了罗盘方位，费力地脑算着目前的大致航行位置。

lindbergh设定一个指南针，当然前往巴黎。

There are theories which can account for the orienting feats of honeybees and migrating birds, but an ability to orient on a compass course is not enough for navigation in the proper sense .

解释蜜蜂和迁移鸟类的惊人的确定方向本领的各种理论并不缺乏，但是，若就导航一词的本意而言，那么根据罗经航向确定方向的能力，尚不能满足导航的要求。

The ship-rudder parameters recording and analyzing instrument is used to carry on real-time date capture and date record of the compass course ,the log speed and GPS shipping direction in the navigation process.

该记录分析仪用于对舰船航行过程中的罗经航向、计程仪航速和GPS舰位等数据进行实时采集和记录，并依据采集数据辨识舰船运动模型参数，以便于操舵控制系统的设计与维修调试。
