GNSS GLOBAL NAVIGATION SATELLITE SYSTEMS
With the launch of the first artificial satellite was born the satellite navigation. The academic world perceives the brilliant idea that it was possible, on the basis of astronomical knowledge of the planetary system, design and implement a positioning system identical to the one already used by sailors.
With the official statement of operations by the DoD (Department of Defence, 1964), became the first operational satellite system TRANSIT-SATNAV with a constellation of polar orbits that by measuring Doppler shift allowed the sailors the opportunity to determine their positions after the passage of
the satellite. Subsequently, based on the know-how acquired in the management of TRANSIT, the DoD designs and builds the first satellite system GPS global coverage stated full operation in 1997.
From this date, several governments are beginning to plan and design the construction of satellite systems like GPS with autonomous management as GLONASS, GALILEO, BEIDOU, IRNSS, the SBAS (Satellite Based Augmentation Systems like EGNOS, WAAS, QZBAS and GAGAN) systems and ABAS (Autonomous Based Augmentation System).
The book contains descriptive references, organizational, management and development of satellite systems are already operating as GPS and GLONASS, and those under development such as the European Galileo, the Chinese BEIDOU and the Indian INRSS. Moreover, under the acronym SBAS, different
differential systems operate with satellite support provided by geostationary satellites that have the function of receiving the corrections processed by the ground control stations (RIMS).
With the same objective, but not bound by external support, there are the receivers ABAS (Autonomous Based Augmentation System) working with specific internal algorithms known by the acronym RAIM with the objective of ensuring the integrity and accuracy of the service PVT particularly necessary in the field of air navigation.
All these systems have contributed to the transition from classical autonomous navigation to enslaved navigation known in the environment navigational stands as e-Navigation (enhanced navigation).
The book contains numerous applications with which the readers can enter into the heart of the satellite systems listed and practice to develop their own application to verify their state of learning the complex problem of the calculation of satellite positioning.
Was full Professor of Navigation at the Faculty of Science and Technology of the Parthenope University (formerly the IUN University), Naples Italy.
Starting in 1972 his research interests were Navigation, Cartography, VTS (Vessel Traffic Services), Electronic Cartography, Space Navigation and Astronomical Navigation. The research fields were in particular in the GNSS (GPS, GLONASS, GALILEO SBAS and ABAS), Loran-C, Omega, INS (Integrated Naviga
tion Systems), PFT2 (Project Targeted Transport 2) and PNRA (National Research Program in Antarctica).
Since 1993, he has been scientific leader of positioning systems in Antarctica (1993-2014). Chairman of the scientific committee for the ENC (European Navigation Conference - Naples 2009), Vice President of the IIN (2005-2012).
In the last twenty years, his scientific activist embraces all aspects of GNSS research, Electronic Cartography (GIS) and AIS (Automatic Identification System); in this sector he coordinated the design and implementation of integrated systems in the emerging branch of e-Navigation. During his scientific ac
tivity he has published over 160 scientific papers and presented numerous articles at the IAIN and GNSS international conferences; He is the author of 22 didactic volumes. President of the courses of Nautical Sciences and Sciences and Technologies of Navigation and professor of the following courses:
Space Navigation (1985-1991), Navigation I (1990-1991), Navigation Astronomical (1992-1997, 2006-2009), Topography and Cartography (2000-01) and Astronomy (1998-99, 2001-02) and professor of navigation (1991-2013).
Since November 2013 he is prof extraordinary retired and on line University Giustino Fortunato, Benevento Italy.
