This algorithm uses the GPS satellite system for navigation. It is an innovative algorithm, because it employs only the Doppler measurements and starts with a known initial location of the receiver. Initially, this algorithm was developed for fixed point GPS transmitters. In the paper we have successfully attempted to adapt this algorithm for moving satellites. This algorithm appears to perform...

Due to insufficient Radio Navigation Satellite Service (RNSS) portion of Radio Frequency (RF) spectrum for many services that are being planned for the future on L band where has come up a frequency overlapping situation, C band as an alternative spectral allocation has already been proposed in the previous years. The future C band signals could make use of the frequency band between 5010MHz an...

Joe J. Khalife is a Ph.D. student at the University of California, Riverside and a member of the ASPIN Laboratory. He received a B.E. in Electrical Engineering and an M.S. in Computer Engineering from the Lebanese American University (LAU). From 2012 to 2015, he was a research assistant at LAU.

Once considered novelties, In-Vehicle Infotainment (IVI) applications have become “must-have” options for many people living in a screen-to-screen world. Today’s consumers expect vehicles to be equipped with features such as digital radio, Internet, DVD video and MP3 systems, and GPS navigation. The challenge for the automotive industry is how to address this opportunity seamlessly, quickly and...

We present a novel technique for navigating lists of everyday life containing phone contacts, TV channels, radio programs, music albums, etc. on handheld devices such as mobile phones, remote controls... Our technique addresses the selection of favorite items in moderate sized lists using absolute and relative finger positioning. It also allows eyesfree navigation among favorite items.

Conventionally, visually impaired people using white cane or guide dog for traveling to desired destination. However, they could not identify their surround easily. Hence, this paper describes the development of navigation system which is applied to guide the visually impaired people at an indoor environment. To provide an efficient and user-friendly navigation tools, a navigation device is dev...

In the last years, an increasing interest of the market in devices able to integrate navigation and communication technologies has been noticed. Software Defined Radio technology helps in a tight integration of all possible radio signals into one, completely reconfigurable, universal device. In this work the problem of integration of Galileo, Satellite UMTS (S-UMTS) and IEEE 802.11b local wirel...

Unmanned ground vehicle is an autonomous vehicle that mainly capable to do tasks independent of humans. Automated vehicle works during off road navigation and mainly used in military operations. The radio environment on electrically small platforms is changing rapidly. In order to support high speed audio and video, processing needs higher data rates concerned with sending and receiving data pa...

GPS receivers have been profitably employed by researchers for investigations into ionospheric and atmospheric science. However, a number of improvements in measurement accuracy are necessary for today’s applications. The ionosphere has practical importance in GPS applications because it influences transionospheric radio wave propagation. Total Electron Content (TEC) is one of the parameters of...
