I think the Doppler measurements can be omitted for static
positioning. CSRS-PPP results for a submission with/without Doppler
are identical.

It seems the carrier phase is not used for single frequency
submissions. The summary file says
Observation processed        :   CODE

For dual frequency,
Observation processed        :   CODE&PHASE
and there are carrier phase residuals in the PDF report.
