After the recent landmark achievement of certification of Indian SBAS System GAGAN for RNP 0.1 operations, India is hosting two back to back high-level technical meetings i.e. 4th Ionospheric Study Task Force (ISTF/4) under the aegis of ICAO and the 26th Interoperability Working group in New Delhi , providing further impetus to harmonized development of Satellite Based Navigation systems across the world.

The solar activity generates Electromagnetic radiations and Energetic Charged Particles in addition to the Galactic Cosmic Radiation that directly impact the earth magnetosphere and then the ionosphere.

On the 15th of October 2013 the European GNSS Agency (GSA) released the latest version of its GNSS Market Report. The Market Report brings an updated and enhanced view of the GNSS global market “as it is experimenting rapid developments”. It encompasses a larger scope than before

Applications and services based upon GNSS are becoming increasingly embedded in modern society, to the extent that we Europeans, along with much of the rest of the World, have now become critically dependent upon their correct operation. In the event of GNSS problems, telecommunications networks…

As more GNSS satellites will be operational within the next few years, the confidence of the position and timing solution for the user is expected to increase. On the other side from the integrity point of view the user faces new problems. It has to protect itself against more potential failures that might occur…

Galileo is Europe’s contribution to the multi-GNSS to provide a highly accurate, guaranteed global positioning service under civilian control. Offering dual frequencies as standard, Galileo is expected to deliver extremely good realtime positioning accuracy. From users’ point of view, availability of Galileo’s signal would help in achieving a multi- GNSS environment for redundancy and system independence.

The territory of the Balkan Peninsula (BP) is one of the most active geodynamical regions in Europe. Numbers of publications are devoted to this problem. An important indicator in geodynamical point of view is an eventual station movement of GNSS network stations. Determination of the size and direction of the vectors of movement, their analysis and assessment is of significant importance for their further interpretation with a view to present the geodynamical picture of the region.

Global Navigation Satellite System (GNSS) technology has revolutionised the way 3-dimensional positions are determined on and above the Earth’s surface. GNSS-based positioning has become a vital tool for a wide range of applications in areas such as surveying, mapping, asset management, precision agriculture, engineering and construction. A lesser known application that has benefited immensely from the introduction of GNSS technology is animal tracking.

The main focus of this paper is the spectral and spatial characterization of GNSS jammers with specific emphasis on multi-frequency wideband jammers which are able to simultaneously jam up to three frequencies. The paper extends previous analysis to jammers also operating in the L2 and L5 bands

Time series that can fi nd application in every area of science as related to its associated technology are often indispensable application area in the science of statistics, and sometimes in econometrics.
