绝对计程仪
绝对计程仪(Absolute Log)是记录船舶相对于海底的航速与航程; 多普勒计程仪、声相关计程仪。
Normalize复选框确定是使用相对于日志(规范)开始的时间还是使用绝对时间(非规范)。
With the electromagnetic Log compared with high accuracy, to measure absolute speed, range, to measure the ship horizontal speed advantages.它与电磁计程仪比较具有测量精度高;能够测量绝对航速、航程;能够测量船舶横向移动速度等优点。
This kind of log is sensitive to small changes measured in the absolute value of the parameter.这种测井对被测参数绝对值的微小变化反映很灵敏。
