The e-navigation concept was introduced by the IMO to enhance berth-to-berth navigation towards enhancing environmental protection, and safety and security at sea by leveraging technological advancements. Even though a number of e-navigation testbeds including some recognized by the IALA exist, they pertain to parts only of the Integrated Navigation System (INS) concept. Moreover, existing e-navigation and bridge testbeds do not have a cybersecurity testing functionality, therefore they cannot be used for assessing the cybersecurity posture of the INS. With cybersecurity concerns on the rise in the maritime domain, it is important to provide such capability. In this paper we review existing bridge testbeds, IMO regulations, and international standards, to first define a reference architecture for the INS and then to develop design specifications for an INS Cyber-Physical Range, i.e., an INS testbed with cybersecurity testing functionality.

A constrained low-cost SINS/OD filter aided with magnetometer is proposed in this paper. The filter is designed to provide a land vehicle navigation solution by fusing the measurements of the microelectromechanical systems based inertial measurement unit (MEMS IMU), the magnetometer (MAG), and the velocity measurement from odometer (OD). First, accelerometer and magnetometer integrated algorithm is studied to stabilize the attitude angle. Next, a SINS/OD/MAG integrated navigation system is designed and simulated, using an adaptive Kalman filter (AKF). It is shown that the accuracy of the integrated navigation system will be implemented to some extent. The field-test shows that the azimuth misalignment angle will diminish to less than 1°. Finally, an outliers detection algorithm is studied to estimate the velocity measurement bias of the odometer. The experimental results show the enhancement in restraining observation outliers that improves the precision of the integrated navigation system.

Describes briefly ultrasonic positioning system (UPS) and digital magnetic compass (DMC) heading measurement principle,analyzed the advantages and disadvantages of each option. To improve the accuracy of the heading measurement, As the theoretical basis of adaptive Kalman filter, designed a kind of ups and dmc integrated navigation system. Based on both real measurement data, made a simulation experiment and confirmed the feasibility of the navigation system.
