  ship ' s speed
In heavy navigation traffic areas and within coastal zones, correct selection of a ship's speed, when accompanied by the necessary trajectory changes, is a crucial element of safe navigation.
      
This paper presents a modernized version of the evolutionary ship trajectory planning system in which a new parameter was introduced, namely changes of the ship's speed along particular sections of the trajectory.
      
Here, an additional operator was added to the system that mutates the ship's speed.
      
Calibration errors, whether of amplitude or of orientation relative to north, cause absolute velocity errors proportional to the ship's speed.
      
DIPS also acquires ship's speed, depth, and heading from either synchro or digital sources with a sampling rate of approximately once per second.

Many efforts have been made abroad to improve the stopping ability of large ships, this article gives a synoptic analysis of some of the conclusions. Controlling the approaching speed and using the "rudder cycling" stopping manoeuver are favorable to the minimization of the stopping distance. It is very important for ship officers to know the emergency stopping distances of large ships under various conditions. For this purpose, four methods for calculating stopping distances are given here, the choice is to be made according to the information available from the specifie ship, this article also recommends the usefulness of making emergency stopping curves beforehand for each ship.

国外为改善大型船舶的停止性能己经做了很多工作.本文对他们的研究结果的倾向性意见作了概括的介绍.控制船舶速度、采用左右舵操纵,对减少倒车冲程是可取的.从船舶驾驶员要求出发,掌握大船在不同状态下的倒车冲程,对保证航行安全实为重要.为此,列举了4种计算冲程的方法,以便根据所能取得的实船资料加以选用;同时推荐预先制定的冲程计算图表,以备查用.

The conventional gyrocompass is inherently made with pendulosity which results the ballistic errors as the ship undergoes a change in course or speed. In the electrically torqued gyrocompass if both the velocity and latitude errors are corrected by applying bias voltages in the loops, the gyro spin axis should indicate the true north. Northerly acceleration causes deviations from its equilibrium position. If the period of maneuver is short in comparison with the period of oscillation of the gyrocompass, the...

The conventional gyrocompass is inherently made with pendulosity which results the ballistic errors as the ship undergoes a change in course or speed. In the electrically torqued gyrocompass if both the velocity and latitude errors are corrected by applying bias voltages in the loops, the gyro spin axis should indicate the true north. Northerly acceleration causes deviations from its equilibrium position. If the period of maneuver is short in comparison with the period of oscillation of the gyrocompass, the deviations of spin axis both in tilt and azimuth are approximately proportional to the change of the north velocity of the ship. The output signal of pendulum can thus be compensated by a well designed device to minimize the ballistie errors.

陀螺罗经的找北过程是和它的摆性密切相连的,因此在船舶机动航行时总会产生惯性误差。电控陀螺罗经由于摆和力矩装置之间的联结是可调的,因此有可能采取一些有力的措施以减小惯性误差。本文分析了船舶机动航行时电磁摆的输出特性。如果对这、纬误差没有采取加知补偿的措施,电控陀螺罗经还是要按舒勒周期考虑参数设计。如果对速、纬误差已采取补偿措施,就不必遵循舒勒周期了。陀螺主轴就应力图保持在水平、真北位置。机动航行时摆有输出信号,因而导致陀螺罗经产生误差。通常船舶的机动航行时间比起正常的罗经周期要小得多,因此惯性误差实际上和北向速度相关。对于单独的陀螺罗经,北向加速度的真值是不好测量的。我们可以利用船舶的速度信号设计补偿装置以大大减小陀螺罗经的惯性误差。
