Moscow in the evening

The ninth International Satellite Navigation Forum will take place during the Navitech exhibition at the Expocentre Fairgrounds in Moscow, Russia on April 22 and 23, 2015.

The main goal of the forum is to inform the national and international audience about the current status and plans for the development of the GLONASS navigation system and foreign satellite navigation systems, state policies in the field of the commercial use of the GLONASS system in Russia and overseas, innovative technologies, and up-to-date navigation equipment and service.

SIDEBAR: Locating a Distress Beacon Activated in Flight

Operational requirements for second-generation emergency location terminal (ELT) beacons have raised the possibility of activating a beacon during flight. This represents a major change in the use of a Cospas-Sarsat distress beacon.

In October 2012 CNES conducted an experiment to verify the possibility of detecting and locating an ELT beacon activated in flight. As the final specifications for second-generation beacons were not defined at that time, a flexible first-generation beacon was used.
