Officials for the Munich Satellite Navigation Summit announced the theme for the 2019 event while attending the ION GNSS+ conference in Miami last fall and are now preparing for their 2019 conference in the spring.
“Augment Yourself with GNSS…” will be the theme of the 2019 edition of the Munich Satellite Navigation Summit, taking place on March 25–27, 2019 at the Alte Kongresshalle in Munich. The organizing Institute of Space Technology and Space Applications (ISTA) of the Universitaet der Bundeswehr Muenchen will invite experts from all over the world to talk about the latest news on Positioning, Navigation, and Timing and their role for Augmented/Mixed Reality as well as other up-to-date technologies.

BLUEGNSS is a project developed in the framework of the Horizon 2020 (H2020) program involving four ANSPs of different European countries (Italy, Cyprus, Greece, and Malta) plus one industrial partner, IDS (Ingegneria Dei Sistemi). The project objective is to harmonize the implementation of PBN approach operations among the BLUE-MED FAB States. This article provides an overview of the phases required to reach this goal and focuses on GNSS performance assessment as recommended by ICAO.

Snapshot positioning is a technique for determining the position of a Global Navigation Satellite System (GNSS) receiver using only a very brief interval of the received satellite signal, where the sampling time can be more than 100 milliseconds (ms) or even down to as little as 2 ms. In comparison, a conventional GNSS receiver may require anywhere between a few and tens of seconds of signal tracking before it is able to compute its first position.

This article — Part 1 was published in the September/October 2018 issue — presents the authors’ experience in setting up an airborne pseudolite (UAVlite) with the needed ground-based infrastructure to perform code and phase ranging performance analysis. UAVlites transmit GNSS-like signals free from any local transmitter multipath (in contrast to ground-based transmitters) and can in principle be localized in real-time through a synchronized network of ground stations which may also broadcast the UAVlite positions in real-time.
