> Are there any specific use cases where this will see outside benefit (urban areas)? When you only way have one radio signal from a satellite, it is impossible to tell how the ionosphere has effected the signal. When you have two, and each a slightly different frequency, you can model signal path changes and apply some corrections for better general accuracy.
