Hi @Onyx,
Just wanted to confirm comments about using the PPP service. It should work fine for you. To record the logs for the PPP service, you can follow the steps from this guide.
As Bryan said, you can wait till you get precise coordinates from the PPP service. However, final ephemerids become available 13–15 days after the end of the week in which the logs are recorded. So as not to wait all this time, you can also do the survey locally with the meter-accurate position of the base. And then, when you get the coordinates from the PPP, just shift the data. The workflow is described here.
