Aiming to provide navigational framework upcoming early lunar exploration missions by rovers, interests in robust and low-cost global satellite navigation systems (GNSS) around the Moon are growing more than ever before. In response, dual-satellite (LGNS) based on Multi-epoch Double-differenced Pseudorange Observation (MDPO) algorithm was proposed our earlier work. While MDPO-based LGNS can rea...

This article mainly studies automatic navigation control methods for agricultural machinery. The navigation system takes RTK-DGPS and inertial measurement unit as positioning sensors. The preview control mode was researched for curve path tracking. The preview control model is to determine the aiming point and calculate the lateral deviation. Automatic turning was realized by fuzzy control meth...

Integrated navigation algorithms under the grid frame have been proposed based on the Kalman filter (KF) to solve the problem of navigation in some special regions. However, in the existing study of grid strapdown inertial navigation system (SINS)/Doppler velocity log (DVL) integrated navigation algorithms, the Earth models of the filter dynamic model and the SINS mechanization are not unified....

introduction: brain computer interface (bci) systems based on movement imagination (mi) are widely used in recent decades. separate feature extraction methods are employed in the mi data sets and classified in virtual reality (vr) environments for real-time applications. methods: this study applied wide variety of features on the recorded data using linear discriminant analysis (lda) classifier...

Autonomous mobile entity navigation through dynamic and unknown environments is an essential part of many mission critical applications like search and rescue and fire fighting. The dynamism of the environment makes it particularly difficult to achieve navigation using just on-board sensors and existing navigation methods. This motivates the integration of wireless sensor networks with navigati...

Speech-based technology is a useful alternative to traditional input techniques such as the keyboard and mouse. For people with disabilities that hinder use of traditional input devices, a hands-free speech-based interaction solution is highly desirable. Various speech-based navigation techniques have been discussed in the literature and employed in commercial software applications. Among them,...

Although outdoor navigation systems are mostly dependent on GPS, indoor systems have to rely upon different techniques for localizing the user, due to unavailability of GPS signals in indoor environments. Over the past decade various indoor navigation systems have been developed. In this paper an overview of some existing indoor navigation systems for visually impaired people are presented and ...
