Is there post processing with a known point?

We have an upcoming mapping project in a remote area in South America. We have to place several GCP markers down in a large area that we know has no cell service (so no chance to connect to a CORS network even if there is one). We do know there are a few previously surveyed points in the area that we will be. If we place our base station over one of these known points and manually set it’s coordinates, do I need to still post process the points to a reference station? I’m assuming no since the baselines would be measured from a known point, I just wanted to get clarification. I don’t think post processing is an option either since no one from the local lands and surveys agency seems to have even heard of the word “RINEX”.

You are right, if you set the base over a known point your whole RTK survey will be referenced to it.
