Abstract

Accurate position measurements are extremely valuable in the shipping industry for various reasons such as safety (collision avoidance), security (situational awareness), fuel-saving (weather identification), punctuality (route prediction), etc. Although GNSS (Global Navigation Satellite System) receivers installed on-board the ships are proven to be highly accurate, the data logging process may occasionally be problematic, mainly due to the complexity of the measurements and the decimal precision that is required. Data were collected from 3 years of operations of 228 Maersk Line container vessels and an analysis reveals that there is a substantial amount $(\approx 20 %)$ of historical position measurements sent to shore that does not reflect reality. In the study, the sources of the faulty logged position measurements are categorized and an interpolation methodology is proposed to validate and correct them by using AIS (Automatic Identification System) data.

自动记录位置测量的验证和校正

准确的位置测量在航运业中非常有价值，因为各种原因，如安全(避免碰撞)，安全性(态势感知)，节省燃料(天气识别)，准时性(路线预测)等。虽然安装在船上的GNSS(全球导航卫星系统)接收器被证明是高度精确的，但数据记录过程有时可能会出现问题，主要是由于测量的复杂性和所需的十进制精度。我们从228艘马士基航运集装箱船的3年运营数据中收集数据，分析显示，发送到岸上的历史位置测量数据中有大量(≈20%)与实际情况不符。本文对测井位置测量错误的来源进行了分类，并提出了一种利用AIS(自动识别系统)数据对其进行验证和修正的插值方法。
