Harmonizing GPS, GLONASS, BeiDou and Galileo
The world's GNSS programs don't comprise a classical quartet, weaving
Mozart stanzas in disciplined execution. They are more like a new jazz
combo, riffing off each other while trying to get in the groove.
GNSS Vulnerability and Mitigation Techniques
The GNSS Authentication and User Protection System Simulator (GAUPSS) is an innovative testbed that creates realistic scenarios for GNSS threats. The testbed can identify weaknesses of detection mechanisms in user equipment, test the effectiveness of new receiver-based mitigation techniques, and evaluate system-level schemes to guarantee the authenticity of received signals.
Multiple signals on multiple frequencies provide the opportunity to develop new techniques for applying reflectometry. This article describes an E1/E5a/E5b ground-based altimetry application that has been tested with Galileo signals, including the use of AltBOC code measurements.
Centrifugal vs. Centripetal Forces
The temptation to shape regulatory measures, market initiatives, or
technology development in ways that unfairly benefit one’s own program
battles the idea that we are all in this together, or should be.
Not Just Galileo, but GNSS
Industry insiders have always known that you don’t need Galileo to make money and create jobs in the GNSS universe. And for many, the center of that universe is rapidly moving towards Asia.

Can we get a little help here?
Omnipresence. GNSS systems are global by nature, but they can’t provide reliable positioning anytime, anywhere. Meet their new friends.
