Engr. Zeeshan Ali is Currently a PhD Student at university of Naples 'Parthenope' working at IREA-CNR and regular faculty member at Department of Telecommunication Engineering, Dawood University of Engineering and Technology (on study leave for PhD) since February 2015. Mr. Ali earned a Master degree from University of Rome ‘Tor Vergata’ (Italy) in “Advance Communication & Satellite Navigation System” under the European Commission’s scholarship named as ‘Erasmus Mundus’ and a Bachelors of Engineering (B.E) in Electronics Engineering from Mehran University of Engineering & Technology Jamshoro, during master degree he has worked on different projects of European Space Agency (ESA), SERCO SpA Limited, Rome, Italy. Later on, he joined QUEST as a lecturer and then he went and pursued for specializing course on Satellite Navigation system from Politecnito di torino, Italy. Currently Mr. Ali has 4 publications in international conferences and supervised many undergraduate group of students. Engr. Zeeshan Ali has achieved many international and national honors/awards like he has also been selected/won scholarship for the summer course in Tokyo-Japan for a week on Global Navigation Satellite System GNSS. He has an honor of became the life member of Japan Science club ‘Sakura’. Mr. Ali has been invited to be a keynote speaker and co-chair in an international conference at ist Islamabad.
Title: Satellite Communications and Global Navigation Satellite Systems (GNSS) based Navigation
The next decade promises drastic improvements to global navigation satellite Systems as Communication is became one of the most essential part of a life of mankind and there is no doubt that satellite communications turned a tremendous pace in this matter. The goal is to create uninterrupted, unlined, high output connectivity no matter what is location. In reality that this is possible because of the presence of electromagnetic waves . Satellites navigation signals and broadcast a GPS look-alike signal containing integrity and wide-area differential correction augmentation data. The net effect is to improve on the integrity (i.e., the assurance that all functions of the system perform with operational limits), accuracy (i.e., precision), availability (i.e., the ability of the system to perform the intended function upon initiation) and continuity (i.e. the ability of the system to provide its service without interruption during an operation) of GNSS services. The USA is enhancing the GPS, Russia is refreshing GLONASS, Europe is moving ahead with its own Galileo system, and The People’s Republic of China is expanding its BeiDou-1 system from a regional navigation system to a full constellation global navigation satellite system known as BeiDou-2/Compass, which consists of thirty five satellites including geostationary satellites, MEO satellites and geosynchronous satellites in the coming year. Extra satellites will make possible improved performance for all applications, and especially where satellite signals can be obscured, such as in urban canyons.
