Inventi Impact - Navigation & Observation
-
Journal Scope:
Originally apportioned for sea and space navigation, ‘Inventi Rapid/Impact: Navigation & Observation’ has broadened its scope by including all kinds of navigations e.g. web navigation and robotic navigation inside a human body. Hence, the journal now is interdisciplinary bridging many practice areas including engineering, astronomy, marine sciences, medical sciences and robotics.

NEW INDOOR NAVIGATION SYSTEM FOR VISUALLY IMPAIRED PEOPLE USING VISIBLE LIGHT COMMUNICATION
In this study, we propose an indoor navigation system that utilizes visible light communication technology, which employs LED lights and a geomagnetic correction method, aimed at supporting visually impaired people who travel indoors. To verify the effectiveness of this system, we conducted an experiment targeting visually impaired people. Although acquiring accurate positional information and det...

A KNOWLEDGE REPRESENTATION APPROACH USING FUZZY COGNITIVE MAPS FOR BETTER NAVIGATION SUPPORT IN AN ADAPTIVE LEARNING SYSTEM
In this paper a knowledge representation approach of an adaptive and/or personalized tutoring system is presented. The domain knowledge should be represented in a more realistic way in order to allow the adaptive and/or personalized tutoring system to deliver the learning material to each individual learner dynamically taking into account her/his learning needs and her/his different learning pace....

USE OF THE WAVELET TRANSFORM FOR INTERFERENCE DETECTION AND MITIGATION IN GLOBAL NAVIGATION SATELLITE SYSTEMS
Radio frequency interference detection and mitigation are becoming of paramount importance due to the increasing number of services and applications based on the position obtained by means of Global Navigation Satellite Systems. A way to cope with such threats is the implementation in the receiver of advanced signal processing algorithm able to raise proper warning or improve the receiver performa...

A SIMPLE THREE-DIMENSIONAL MATRIX METHOD FOR GLOBAL CONSTELLATION INTRASATELLITE LINK TOPOLOGICAL DESIGN
A three-dimensional matrix method is proposed in this paper for Global Navigation Satellite System (GNSS) constellation Intrasatellite Link (ISL) topological design.Therows and columns of proposedmatrix contain the information of both constellation orbit planes and satellites in each orbit plane. The third dimension of proposed matrix represents the time sequences during constellation move...

UNDERLAY COGNITIVE RADIO WITH FULL OR PARTIAL CHANNEL QUALITY INFORMATION
Underlay cognitive radios (UCRs) allow a secondary user to enter a primary user’s spectrum through intelligent utilization of multiuser channel quality information (CQI) and sharing of codebook. The aim of this work is to study two-user Gaussian UCR systems by assuming the full or partial knowledge of multiuser CQI. Key contribution of this work is motivated by the fact that the full knowledg...

COMBINED ACQUISITION AND TRACKING METHODS FOR GPS L1 C/A AND L1C SIGNALS
As part of the GPS modernization, the GPS L1 C/A signal will be augmented by the L1C signal. With this improvement, for the first time, several signals from the same constellation will be available at the same frequency. In this paper, an acquisition method is implemented to combine the GPS L1 C/A and L1C signals before correlation. The combined acquisition succeeds to acquire the signal at low...
