Global Navigation Satellite Systems (GNSS) have become an essential part of maritime navigation, in particular to improve situational awareness and vessel traffic management. The dependence on GNSS creates vulnerability for maritime shipping. Driven by this vulnerability, the desire for a backup system for maritime navigation has been emerging. The VHF Data Exchange System (VDES) standard provides communication capabilities for maritime applications. VDES is currently being revised. As part of this revision, VDES will be extended by ranging and navigation functionalities, called R-Mode, as an alternative for maritime navigation. In this paper, we address system design aspects and evaluate the positioning performance of VDES R-Mode. We derive estimation theory bounds on the accuracy of VDES R-Mode distance and velocity. In a case study, we discuss and evaluate the benefit of satellite links to complement VDES R-Mode positioning. Furthermore, we introduce a Kalman filter for position and velocity tracking, which we apply to experimental data. We describe an experiment we conducted at Lake Ammer, southwest of Munich, and evaluate the VDES R-Mode positioning performance for this setup. Our experimental results show that VDES R-Mode is capable of achieving a 95th-percentile horizontal position error of 22 m. Thus, VDES R-Mode is a promising approach for a maritime backup system that can meet the IALA accuracy requirements.

VDES R-Mode性能分析和实验结果

全球导航卫星系统 (GNSS) 已成为海上导航的重要组成部分,特别是用于提高态势感知和船舶交通管理。对 GNSS 的依赖给海运造成了脆弱性。在这种脆弱性的驱使下,对海上导航备份系统的需求不断涌现。VHF 数据交换系统 (VDES) 标准为海事应用提供通信能力。VDES 目前正在修订中。作为此次修订的一部分,VDES 将通过称为 R 模式的测距和导航功能进行扩展,作为海上导航的替代方案。在本文中,我们解决了系统设计方面的问题并评估了 VDES R-Mode 的定位性能。我们推导出 VDES R 模式距离和速度精度的估计理论界限。在一个案例研究中,我们讨论和评估卫星链路对补充 VDES R-Mode 定位的好处。此外,我们引入了用于位置和速度跟踪的卡尔曼滤波器,我们将其应用于实验数据。我们描述了我们在慕尼黑西南的阿默湖进行的实验,并评估了该设置的 VDES R-Mode 定位性能。我们的实验结果表明,VDES R-Mode 能够实现 22 m 的 95% 水平位置误差。因此,VDES R-Mode 对于能够满足 IALA 精度要求的海事备份系统来说是一种很有前途的方法。慕尼黑西南部,并评估此设置的 VDES R-Mode 定位性能。我们的实验结果表明,VDES R-Mode 能够实现 22 m 的 95% 水平位置误差。因此,VDES R-Mode 对于能够满足 IALA 精度要求的海事备份系统来说是一种很有前途的方法。慕尼黑西南部,并评估此设置的 VDES R-Mode 定位性能。我们的实验结果表明,VDES R-Mode 能够实现 22 m 的 95% 水平位置误差。因此,VDES R-Mode 对于能够满足 IALA 精度要求的海事备份系统来说是一种很有前途的方法。
