Development of new technologies and its growing process in the last years of the twentieth century, leads to the use of satellites in navigation. Although the technical aspects of this project has significantly improved, legal and political aspects of it, have been subject of different views of states and of international organizations related to aviation industry and though have not led to a f...
متن کاملGlobal navigation satellite systems
Global positioning systems first became available for private use in 1995. Since the introduction of NAVSTAR-GPS (Navigation System with Time and Ranging–Global Positioning System) and GLONASS (Globaluaya Navigatsionnaya Sputnikovaya Sistema, Global Navigation Satellite System), such systems have quickly become indispensable in a wide range of applications. Above all, GPS is used today by a lar...
متن کاملThe ionosphere , radio navigation , and global navigation satellite systems
This article is a review of Global Navigation Satellite Systems for space scientists who are interested in how GNSS signals and observables can be used to understand ionospheric dynamics and, conversely, how ionospheric dynamics affect the operational capabilities of GPS. The most common form of GNSS is the Global Positioning System (GPS); we will first review its operating principles and then ...
متن کاملAtomic Clocks and Timing Systems in Global Navigation Satellite Systems
Accurate and ultra-stable atomic clocks have been recognized as the critical equipment for the precision Global Navigation Satellite Systems (GNSS). SpectraTime (SpT) and T4Science (T4S) are space and ground clocks manufacturers of Rubidium Atomic Frequency Standard (RAFS) and Active & Passive Hydrogen Maser (HM) for various navigation systems (European, Chinese and Indian) and other programs. ...
متن کاملAnalysis of Anti-Jamming Techniques for Satellite Navigation Systems
GNSS(Global Navigation Satellite System) is now being widely used in both civilian and military applications where accurate positioning and timing information are required and it is considered as a representative convergence technique in IT-Military application techniques. However, GNSS has low sensitivity level of GNSS receivers and is vulnerable to jamming signal, since the signals come from ...
