Hi Bruce,
interesting article. Also don't forget Glonass, the Russians are investing a
large amount of money to get and maintain their system up and running, while
Galileo is still a dream.
bye,

They also use a neural net for modeling prediction of atmospheric delays.
Perhaps the ultimate is to implement a custom GPS receiver (apart from the
RF front end and ADC) in a large FPGA.
One could then use L1, L2C, L5 etc plus the Galileo signals when they become
available.
