Strictly speaking, yes. The important term is "original GPS data" which
is, prinicipally, the pseudoranges to each satellite used in the
position solution - which most consumer GPS receivers do not provide.
If, however, you have access to a GPS receiver that provides
pseudorange and, even better, carrier phase data, software can
post-process that data along with DGPS Type 1, 2 or 9 message
pseudorange delta corrections to achieve high position accuracy.
