Creating and sharing knowledge for telecommunications

Project: Advanced Receivers and Navigation Algorithms for GPS/Galileo Signals

Acronym: ARNAGGS
Main Objective:
The project objectives are to study and develop:
a) Algorithms and methods for fast acquisition of weak navigation signals;
b) Open-loop tracking architectures alternative to the conventional DLL+PLL, based on stochastic nonlinear filtering. Harsh environments such as indoor reception and use of highly-accelerative platforms will be considered;
c) Structures and algorithms for advanced multipath mitigation. Alternative solutions to the double-delta correlation, based on the gating concept, will be proposed;
d) Coordinated positioning techniques;
e) Communication channel models relevant in navigation.
A collaboration with Portuguese companies operating in aerospace activities is foreseen.
