Inland navigation and shipping are important pillars of the European Transport System. To support the skipper during safety-critical operations, precise position, navigation, and timing (PNT) data are required. This work discusses the role of PNT information for enabling inland waterway navigation-assistance functions, such as bridge-collision warning, mooring aiding, and automatic guidance. The real-time kinematic technique is developed to provide integrity information alongside reliable and centimeter-level-accurate PNT data. In addition, the transmission of Global Navigation Satellite Systems (GNSS) correction data is investigated. Since GSM does not currently meet the availability and stability communication requirements along inland waterways, use of the automatic identification system (AIS) for data transmission is explored. The proposed navigation solution and the communication developments were analyzed in real time in challenging GNSS signal-degraded scenarios on the authorized inland waterway testbed. Despite the further developments required for the AIS communication infrastructure, it is shown that our system architecture can nearly meet the integrity and accuracy requirements for driver-assistance functions on inland waterways.

启用内河航道安全航行的辅助功能

内河航运和航运是欧洲运输系统的重要支柱。为了在安全关键操作期间支持船长，需要精确的位置、导航和计时 (PNT) 数据。这项工作讨论了 PNT 信息在实现内河航道导航辅助功能（例如桥梁碰撞警告、系泊辅助和自动引导）方面的作用。开发实时运动学技术以提供完整性信息以及可靠且厘米级精确的 PNT 数据。此外，还研究了全球导航卫星系统 (GNSS) 校正数据的传输。由于 GSM 目前不满足内陆水道沿线的可用性和稳定性通信要求，因此正在探索使用自动识别系统 (AIS) 进行数据传输。在授权的内河航道试验台上，在具有挑战性的 GNSS 信号退化场景中，实时分析了提议的导航解决方案和通信发展。尽管 AIS 通信基础设施需要进一步发展，但表明我们的系统架构几乎可以满足内河航道驾驶员辅助功能的完整性和准确性要求。
