I have the ProMark3 RTK (PM3R) and no one so far can seem to show me a way to take the geoid09.geo file and convert it to a gsf file (geoid separation file) for my unit. Randy Black was nice enough several years ago to create me a gsf of geoid03 for about a 150 mile radius of Tulsa OK but I am confused now when I try to figure out how. Nothing that Ashtech (formerly Magellan Pro) has explains how to do it and I am certain it can be done.
I took the reduced area specific version in geo format and thought I could just change the name to gsf and it would work and be the same. I even loaded it and told my units to use it. I have not done RTK in a while so did not really get to test it. But when I opened both files in notebook, the old file in gsf was readable in text format but the geo was in hieroglyphics (non-readable symbolic).
I suspect the reduce geo that I changed in extension name to gsf is not going to work. Does anyone have a way to convert the file into a for sure usable format I can easily transfer using my SD like I am used to. I hate to think of trying to cable transfer - always have a hard time getting those stupid com ports to work and never want to do a transfer that way again.
