介绍了AIS信号附加二次相位因子实时校正系统的开发与实现。利用研制的ASF校正系统采集了大量的试验数据，分析和验证了AIS信号在海上传播的传播特性和AIS信号的ASF实时校正算法。考虑到陆基定位系统中接收机硬件的不同和实际环境因素的变化，ASF校正系统对定位接收机的原始测量值进行真实的实时校正，校正后的定位精度在10 m以内。
This paper looks at the development and implementation of the additional secondary phase factor (ASF) real-time correction system for the Automatic Identification System (AIS) signal. A large number of test data were collected using the developed ASF correction system and the propagation characteristics of the AIS signal that transmits at sea and the ASF real-time correction algorithm of the AIS signal were analyzed and verified. Accounting for the different hardware of the receivers in the land-based positioning system and the variation of the actual environmental factors, the ASF correction system corrects original measurements of positioning receivers in real time and provides corrected positioning accuracy within 10 m.
