Satellite navigation is critical in signal-degraded environments such as urban
canyons and mountainous area, where many GNSS signals are blocked by natural
and artificial obstacles or are strongly degraded. Hence standalone GPS is often
unable to guarantee a continuous and accurate positioning. A suitable approach
could be the integration of several GNSS. Multi-constellation system guarantees an
improved satellite availability with respect to GPS standalone, providing a
positioning enhancement in terms of accuracy, continuity and integrity. Currently
the ideal candidate for supplement GPS in a multi-constellation approach is the
Russian GLONASS. The main purposes of this work are the performance
assessment of a GNSS multi-constellation relative to GPS stand-alone and the
comparison of Least Squares and Kalman Filter.
