GPS L1/L2 position fixing incapability under heavy foliage is a thing of the past with the advent of GPS L5. This is according to GPS/GNSS sales people. With my very limited knowledge in telecommunication, I shall say without any degree of certainty that this is not true.

To my opinion, the only advantage of GNSS over GPS is the speed of position fixing. This is I guess due to greater number of navigation systems and channels supported. Greater number of satellites, channels, and frequencies provide more data reduction capability thus speedy position fixing. It has no way of determining solutions if signals don't reach the reciever due to heavy foliage.

Any ideas?
