由于天气条件和目标机动，雷达和ARPA具有某些功效限制。因此，用额外信息补充从雷达获得的信息似乎是合理的。一个声称是专门执行这一任务的系统是自动和连续地提供适当的信息。然而，某些用户认为，AIS数据的完整性仍然不够。本文讨论了这类数据的不完全性和完整性问题。为了证明AIS动态数据在避碰中的有效性，进行了详细的研究。分析数据来自格但斯克湾，可追溯到2006-2012年。根据研究结果，当与AIS协同工作的传感器所提供的信息不完全时，存在异常情况。这个问题涉及与HDG和ROT相关的信息，特别是当船只不在“途中”时。
Radar and ARPA feature certain efficacy limitations due to weather conditions and target manoeuvres. Therefore, it appears rational to supplement the information derived from radar with additional information. A system which is claimed to be tailored to perform this task is AIS delivering proper information automatically and continuously. However, in certain users opinion, integrity of AIS data is still insufficient. In this paper, discussion concerning incompleteness and integrity of this type of data is presented. To prove effectiveness of AIS dynamic data in collision avoidance, detailed investigations have been conducted. Analysed data originate from the Gulf of Gdansk, dating back to the years 2006-2012. According to the research results, there are exceptional situations, when the information coming from the sensors cooperating with AIS is incomplete. This problem concerns information related to HDG and ROT, especially, when the vessels are not "on the way".
