      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.
