A new international conference on advanced GNSS and 3D spatial techniques will be held at the University of Trieste, Main Conference Room, H3 Building, on February 18, 19 and 20. It is free to participants.
The conference will focus on GNSS applications for civil and environmental engineering, geophysiques, architecture, archaeology and cultural heritage. It has been organized in memory of Giorgio Manzoni, professional of surveying and mapping at the university.

Working Papers explore the technical and scientific themes that underpin GNSS programs and applications. This regular column is coordinated by Prof. Dr.-Ing. Günter Hein, head of Europe’s Galileo Operations and Evolution.
With the support of the European Space Agency (ESA), a European team designed a frequency- and time-transfer process and validated its performance in a complex navigation test bed. This two-way time-transfer technology took advantage of the following:

Figure 1, 3, 4 & 5Q: What is Doppler collision and is it a problem in GNSS?
A: Doppler collision is a physical effect in code-division multiple access (CDMA) systems where code measurement errors are observed due to cross-correlation effects. Doppler collision may occur when the Doppler frequency between signals from two different transmitters is smaller than the code lock loop bandwidth.

The GPS Aided Geo Augmented Navigation (GAGAN) system was developed by the Indian Space Research Organization (ISRO), together with Airports Authority of India (AAI), to deploy and certify an operational satellite-based augmentation system (SBAS). The system’s service area covers the Indian Flight Information Region (FIR), with the capability of expanding to neighboring FIRs.

Figures and TablesIn satellite navigation, the user receiver finds its position by measuring its distance to satellites and knowledge of the satellite position. The distance is measured by ranging, i.e., finding the delay of the signal from the transmitter to the receiver. The delay will comprise of payload hardware delay and the geometric range delay. Hence, the payload delay of the signal from generation to radiation is very important and needs to be transmitted in navigation data.

Russia will host the eleventh meeting of the International Committee on GNSS (ICG) from November 6 to 11, 2016 in Sochi, on the Black Sea near Georgia. This meeting is organized by Roscosmos, the State Space Corporation. It will take place at the Pullman Sochi Center Hotel and Conference Center.
The ICG is a voluntary United Nations–backed association that brings together GNSS and augmentation providers, including the United States, Russia, European Union, China, India, and Japan.

The sixth international conference on localization and GNSS will take place at the Universitat Autònoma de Barcelona (UAB) – Casa Convalescència, a UNESCO site, on June 28, 29 and 30 in Barcelona, Spain.
ICL-GNSS covers recent research on terrestrial and satellite-based positioning techniques to provide reliable, accurate and low latency position information with the goal of inspiring new design, implementation, test and evaluation methodologies for positioning platforms.
