The European Union Agency for the Space Programme (EUSPA) has published an online interactive world map providing information about augmentation service providers that support Galileo. Clicking over each country shows the names of the Galileo-ready providers along with the name of the service, type of service and coverage.

The U.S. Army has put its replacement for the handheld Defense Advanced GPS Receiver (DAGR) under field testing in reconnaissance and fire missions in a variety of threat scenarios, to understand its performance in a realistic operational environment. The Dismounted Assured Positioning, Navigation, and Timing System (DAPS) could enable warfighters to better shoot, move and communicate in a GPS degraded environment.

Spirent Communications has launched GNSS Foresight, a cloud-based solution that empowers GNSS users with advance knowledge about the strength and reliability of GNSS signals in exact locations within their operational areas. The service will have early application for aviation, unmanned and autonomous platforms, but Spirent VP Jeremy Bennington told Inside GNSS that its potential is far wider.

A new method for multipath rejection employs a multicorrelator-based GNSS receiver with an extended Kalman Filter (EKF) as an iterative solver, replacing the conventional delay locked loop (DLL) code tracking. The technique significantly reduces the positioning error and has low complexity. It can therefore be implemented in a real-time processing environment.
The U.S. Army Research Lab awarded the University of Central Florida a $4.5 million grant to develop a smart, computer vision-based navigation system for when GPS is unavailable or jammed.
