While I don't exactly disagree with the sentiments of that statement, it is wrong and beside the point.  Firstly, there are 6 
countries owning GNSS systems, most receivers can use them all, only one is the US-GPS.  Secondly, there was no problem with the 
GNSS, the problem was with their data connection.

As for other systems, I guess the advantage of a GPS/GNSS based system is that it can be applied to any field at short notice. Other 
systems require complicated hardware to be set up on the field.  I guess cost would be an issue here and I have no idea of the 
relative costs.
