The Cospas-Sarsat MEOSAR System: A Solution to Support ICAO GADSS Autonomous Distress Tracking Recommendation

Today, it appears that the Cospas-Sarsat MEOSAR system, relying on payloads deployed on GNSS constellations (Galileo, GPS, GLONASS), offers all the conditions to meet the new recommendation of ICAO for ADT-system for Commercial Aviation, with a new generation of in-flight triggered beacons, identical to the current ELT in terms of aircraft integration, but capable of receiving triggers and cancellation events from the avionics, from the crew or from internal sensors, and of detecting and managing their inhibitions to maintain the capability to raise alerts and be localized in any situation.

How the Parallel Use of GPS and Galileo Benefits Railway Applications

This article focuses on the research project Galileo Online: GO! – which with support from the Federal Ministry for Economic Affairs and Energy (grant number 50NA1510) designs and develops a reliable and high-precision receiver for multi-constellation and dual-frequency GNSS whose suitability and capabilities are tested in railway applications. Project results showcase the advantages of GPS and Galileo if used simultaneously in railway applications.

GNSS Analysis Tools from Google

Authors: Frank van Diggelen and Mohammed Khider
Google has publicly released GNSS Analysis Tools to process and analyze GNSS raw measurements from your phone. These tools enable manufacturers to see in detail how well the GNSS receivers are working in each particular phone design and thus improve the GNSS design and performance in their phones. Also, with the tools publicly available there is significant value for app-developers, researchers and educators. Here, the authors show what these tools do, and how they reveal details of receiver and signal behavior that are not possible to observe without raw measurements.

House and Senate authorizers are forcing a reorganization of the Pentagon’s management of military space programs, giving authority to a soon-to-be-named official to prioritize space budgets across services and setting planning in motion for a possible new department. They also approved spending the full amounts requested for the military GPS programs and mandated that defense officials both test a backup to GPS and look at incorporating European and Japanese GNSS signals into military user equipment.
