>For GNSS on the other hand, don't care about the bandwidth because it's for location service not streaming video, but the limitations of being pseudo-orthogonal eventually got to them in the form of spoofing vulnerability. Please check my original comments as above. Granted, it's still perhaps feasible to spoof OFDM system but it'll be much harder to pull off compared to the pseudo-orthogonal spread spectrum system [1],[2].
