It would be nice to have a receiver for that when they turn it on, but I
don't think that's what he wants. The observables used for PPP processing
are L1 and L2 carrier phase. You don't need a receiver capable of decoding
the P(Y) code but you do need a receiver capable of receiving the full
bandwidth of its carrier on both L1 and L2 and tracking the phase.
The commercial receivers which do this seem to cost dearly.
The actual hardware isn't expensive, I would think that someone has a
software receiver for this.
