Owing to their numerous merits, such as compact, autonomous and independence, the strapdown inertial navigation system (SINS) and celestial navigation system (CNS) can be used in marine applications. What is more, due to the complementary navigation information obtained from two different kinds of sensors, the accuracy of the SINS/CNS integrated navigation system can be enhanced availably. Thus...

When a high-speed train is running in tunnel, the global navigation satellite system (GNSS) signal completely lost. Relying only on inertial (INS) composed of Micro-electromechanical Systems (MEMS) devices leads to large errors. To solve this problem, an integrated micro measurement unit (MIMU), odometer (ODO), and motion constraint (MC) tunnel method proposed. This first establishes model base...

This paper discusses the use of Airborne Light Detection And Ranging (LiDAR) equipment for terrain navigation. Airborne LiDAR is a relatively new technology used primarily by the geo-spatial mapping community to produce highly accurate and dense terrain elevation maps. In this paper, the term LiDAR refers to a scanning laser ranger rigidly mounted to an aircraft, as opposed to an integrated sen...

© 2013 Munkhzul Enkhtur et al. 943 Instead of the extended Kalman filter, the unscented Kalman filter (UKF) has been used in nonlinear systems without initial accurate state estimates over the last decade because the UKF is robust against large initial estimation errors. However, in a multirate integrated system, such as an inertial navigation system (INS)/Global Positioning System (GPS) integr...

The paper researched and presented a virtual simulation system based on a full-digital lunar terrain, integrated with kinematics and dynamics module as well as autonomous navigation simulation module. The system simulation models are established. Enabling technologies such as digital lunar surface module, kinematics and dynamics simulation, Autonomous navigation are investigated. A prototype sy...

Modern day personal navigation devices are often realized as a multi-sensor integrated navigation system wherein the measurements from various sensors are combined to generate a navigation solution. A fault occurring in any of these sensors can affect the performance of the navigation system, potentially compromising the reliability of the navigation solution. It is thus imperative to detect an...

A robust electronic position, navigation and timing system (PNT) is considered as one of the core elements for the realization of IMO-s (International Maritime Organization) e-Navigation strategy. Robustness can be interpreted as the capability of an integrated PNT system to provide PNT relevant data with the desired accuracy, integrity, continuity and availability under consideration of changi...
