In this paper, we derive a pressure gradient finite element formulation for the compressible Navier-Stokes equations, based on local projections. The methods are stable for P_l/P_l and P_l/P_l-1 combination of discrete velocity and pressure spaces(without requiring a Babuska-Brezzi stability condition). An error estimate is obtained.
