Future automotive GNSS positioning in urban scenarios
Driving in built-up areas, buildings can block the signals from GPS satellites. But if the receiver can access the signals of two or more GNSSs, position fixes might be available where none were possible with GPS alone, and the accuracies of marginal fixes might be improved. The authors look at using multi-GNSS for navigating in the heart of a city and how the additional signals can help us to get where we’re going.
