The application of global navigation satellite system in vehicle navigation imposes high requirements on its safety, which makes it extremely important to detect deceptive interference (DI). The integration of prior road position information is ...

The dead reckoning (DR) is widely used for indoor positioning because it does not rely on external information, but it has the disadvantage of not being able to give an initial position and the problem of error accumulation. When the number of ...

This paper introduces a new algorithm (Gravity & Magnetic North Vector correction — Double SLERP, or “GMV-D”) to estimate the orientation of a MEMS Magnetic/Angular-Rate/Gravity (MARG) sensor module using sensor fusion in the context ...

• Non-Kalman Filter fusion of Magnetic, Angular-Rate and Gravity (MARG) signals.

Odometry calibration adjusts the kinematic parameters or directly the robot’s model to improve the wheeled odometry accuracy. The existent literature considers in the calibration procedure only one steering geometry (differential drive, Ackerman/...

Man has explored less than 5% of three-fourths of the water on Earth. This is mostly due to lack of cheap and effective under-water transportation. Submarines and other deep sea robots, exploration devices and submersible modules have a wide range ...

A persistent pedestrian tracking system is proposed by combining visual signals and Inertial Measurement Unit (IMU).IMU tracking assists visual tracking when the target is occluded.The challenges of IMU tracking (calibration and drift) are alleviated by ...

In this paper, we propose a global positioning system-less localization method, called Hidden Access Point Estimation-based Localization (HAPEL) to pinpoint user's current position in an underground or indoor environment, especially where access points (...

In order to navigate or localize in 3D space such as parking garages, we would need height information in addition to 2D position. Conventionally, an altimeter is used to get the floor level/height information. We propose a novel method for three-...

As satellite signals, e.g. GPS, are severely degraded indoors or not available at all, other methods are needed for indoor positioning. In this paper, we propose methods for combining information from inertial sensors, indoor map, and WLAN signals for ...

In games, the goals and interests of players are key factors in their behavior. However, techniques used by networked games to cope with infrequent updates and message loss, such as dead reckoning, estimate a player's movements based mainly on previous ...

A fault detection and correction methodology for personal positioning systems for outdoor environments is presented. We demonstrate its successful use in a system consisting of a global positioning system receiver and an inertial measurement unit. ...

Improvement of dead reckoning accuracy is essential for robotic localization systems and has been intensively studied. However, existing solutions cannot provide accurate positioning when a robot suffers from changing dynamics such as wheel slip. In ...

We propose a new approach to the simultaneous cooperative localization of a very large group of simple robots capable of performing dead-reckoning and sensing the relative position of nearby robots. In the last decade, the use of distributed optimal ...

Moving objects databases (MOD) manage trajectory information of vehicles, animals, and other mobile objects. A crucial problem is how to efficiently track an object's trajectory in real-time, in particular if the trajectory data is sensed at the mobile ...

The availability of a reliable and precise tracking system for relief units operating in mission critical scenarios would drastically improve the situational awareness and thus facilitate the mission planning and accomplishment as well as increase the ...

We introduce a wearable pedestrian indoor localization system with dynamic position correction. The system uniquely combines dead reckoning and fiducial marker-based localization schemes, exclusively using widely available, low end and low power ...

The ability to locomote is a defining characteristic of all animals. Yet, all but the most trivial forms of navigation are poorly understood. Here we report and discuss the analytical results of an in-depth study of a simple navigation problem. In ...

This paper investigates a Global Positioning system (GPS)-free positioning method for mobile units (MUs) in outdoor wireless environments by using the Bayesian filtering formulation. The procedure utilizes simulated inertial measurements, cell-ID of the ...

This paper discusses the scalability problem of distributed virtual environment (DVE) centered on area of interest (AOI) model and dead reckoning (DR) algorithm. Previous models improving scalability of virtual environment are analyzed and compared, and ...

Abstract: In this paper, we propose a new attitude dead reckoning paradigm in collaborative virtual environment (CVE). We derive a general polynomial construction scheme of attitude trajectory that uses a number of previous packets in order to ...
