“…Dynamic information such as navigation marks and the water level are displayed on the map in real time with good precision. It is suggested that new technologies, such as uncrewed aerial vehicles and ships ( 30 , 31 ), should be combined to improve the renewal speed of I-ENC.…”

As a golden waterway in China, the Yangtze River is one of the busiest waterways in the world. The Changjiang Waterway Bureau has made inland electronic navigational charts (I-ENC) of the Yangtze River from Yibin to Liuhekou. It assists ships in safe navigation and provides information on waterway elements for analysis and prediction. Compared with traditional navigation and information methods, ENCs better promote the safety and efficiency of inland waterway navigation, thereby protecting the environment. The primary tool of this study is the questionnaire, including the basic information, business services, data services, available services, and product services of the Yangtze River I-ENC. This study analyzed the questionnaire combined with on-the-spot investigation, focusing on understanding respondents’ current views on the Yangtze River I-ENC to improve service quality. A total of 885 respondents completed the questionnaire from June 2021 to August 2021. The results show that the Yangtze River I-ENC mainly expands related products, such as Electronic Chart Display and Information System (ECDIS), mobile application, WeChat small program, internet online navigational charts, and paper navigational charts. Mobile application is the most popular among respondents. The primary purpose of I-ENC at the present stage is to assist navigation and improve navigation safety.

“…The use of camera images, e.g., mounted on unmanned aerial vehicles (UAV), is particularly interesting. For example, the authors of [27] proposed a method to correct spatial orientation angle based on a shoreline image for use in coastal and port environments. The use of this type of tool, such as passive cameras, develops the interdisciplinary aspect of navigation, reaching to the achievements of image processing, signal processing and robotics.…”

The diversity and non-uniformity of the positioning systems available in maritime navigation systems often impede the watchkeeping officer in the selection of the appropriate positioning system, in particular, in restricted basins. Thus, it is necessary to introduce a mathematical apparatus to suggest, in an automated manner, which of the available systems should be used at the given moment of a sea trip. Proper selection of the positioning system is particularly important in integrated navigation systems, in which the excess of navigation information may impede the final determinations. In this article, the authors propose the use of the decision-robustness function to assist in the process of selecting the appropriate positioning system and reduce the impact of navigation observations encumbered with large errors in self-positioning accuracy. The authors present a mathematical apparatus describing the decision function (a priori object), with the determination of decision-assistance criteria, and the robustness function (a posteriori object), with different types of attenuation function. In addition, the authors present a computer application integrating both objects in the decision-robustness function. The study was concluded by a test showing the practical application of the decision-robustness function proposed in the title.

“…Due to their extensive capabilities, GNSS/INS systems are primarily used in navigation and transport applications. These include tests using Unmanned Aerial Vehicles (UAV) [8][9][10] and Unmanned Surface Vehicles (USV) [11,12], locating mobile phones [13], indoor [14], terrestrial [15] and space [16] navigation, geodetic [17][18][19] and hydrographic surveys [20][21][22], operating Autonomous Ground Vehicles (AGV) [23][24][25], rail transport, in particular for the purposes of High-Speed Rail (HSR) [26,27], road transport [28][29][30] or preventing intentional interference [31,32].…”

Hydrographic surveys, in accordance with the International Hydrographic Organization (IHO) S-44 standard, can be carried out in the following five orders: Exclusive, Special, 1a, 1b and 2, for which minimum accuracy requirements for the applied positioning system have been set out. They are as follows, respectively: 1, 2, 5, 5 and 20 m, with a confidence level of 95% in two-dimensional space. The Global Navigation Satellite System (GNSS) network solutions (accuracy: 2–3 cm (p = 0.95)) and the Differential Global Positioning System (DGPS) (accuracy: 1–2 m (p = 0.95)) are now commonly used positioning methods in hydrography. Due to the fact that a new order of hydrographic surveys has appeared in the IHO S-44 standard from 2020—Exclusive, looking at the current positioning accuracy of the DGPS system, it is not known whether it can be used in it. The aim of this article is to determine the usefulness of GNSS/Inertial Navigation Systems (INS) for hydrographic surveys. During the research, the following two INSs were used: Ekinox2-U and Ellipse-D by the SBG Systems, which were supported by DGPS and Real Time Kinematic (RTK) receivers. GNSS/INS measurements were carried out during the manoeuvring of the Autonomous/Unmanned Surface Vehicle (ASV/USV) named “HydroDron” on Kłodno lake in Zawory. The acquired data were processed using the mathematical model that allows us to assess whether any positioning system at a given point in time meets (or not) the accuracy requirements for each IHO order. The model was verified taking into account the historical and current test results of the DGPS and RTK systems. Tests have confirmed that the RTK system meets the requirements of all the IHO orders, even in situations where it is not functioning 100% properly. Moreover, it was proven that the DGPS system does not only meet the requirements provided for the most stringent IHO order, i.e., the Exclusive Order (horizontal position error ≤ 1 m (p = 0.95)). Statistical analyses showed that it was only a few centimetres away from meeting this criterion. Therefore, it can be expected that soon it will be used in all the IHO orders.
