The captain ordered a change of tack.

船长下令改变向。

The old helmsman brought us about and we avoided a dangerous dash against the rocks.

老舵手掉转了船向, 我们才避免了一次撞击礁石危险。

The course which will cut each meridian at the same angle is termed a rhumb line.

与每一子午线相一角度向叫恒向线。

Meanwhile, gyroscope and odograph transfer course angle and distance respectively to the computer by serial port.

时，陀螺，里程表等也将目向信息和运行距离结果通过串口传到计算机。
