A Multi-Layered, Multi-Receiver Architecture
Researchers from the University of Illinois at Urbana-Champaign are testing a multi-layered, multi-receiver architecture that protects GPS-based timing against jamming, spoofing, and receiver malfunctions. The results, so far, are good.
The Error Vector Magnitude/Code Tracking Error Relationship
Engineers at the Indian Space Research Organization show that a code tracking error varies linearly with error vector magnitude, a parameter to quantify various impairments of a satellite’s navigation payload.
For Multi-GNSS Positioning in Finland
A team of Finnish researchers describe the results of a recent successful campaign to track signals from the Indian Regional Navigation Satellite System now under development.
Space – the next GPS frontier. Higher-than-GNSS-orbit applications could spur cooperation.
Cospas-Sarsat, a 32-year-old emergency reporting system, is replacing its low Earth orbit satellite component with a GNSS-based architecture to improve its worldwide service. This article describes changes in the space segment and the new signals and user beacons that will be part of this modernization.

New Solutions, New Challenges
More GNSS providers, more satellites, more signals. That must mean more accuracy, more easily — right? Well, not necessarily.
