We develop the previously proposed new interpolation framework which finds intermediate satellite positions and velocities with high precision using only two standard SP3 points. We show that the interpolation coefficients in our method can be set constant for several years. This allows one to use the proposed interpolation framework for solution of navigation problems with high precision.
