geoid09 in gfs format file so I can SD card from PC

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.

  • 2 Should the Geoids module fail to connect to the field terminal, please
    resume the above procedure in Manual Mode, i.e. clear the Automatic transfer
    check box when Geoids displays the above dialog box. This will open the Surv-
    Com window. From this window, you will be able to check the PC port settings
    (cf. Options button), try again to connect to the field terminal (cf. Connect
    button) and then, if the connection is successful, resume data transfer (cf.
    Transfer button). In that case, the file that you would have to select in the left-
    hand pane before clicking the Transfer button would be in the form
    “.gsf” where is the name of the open geoid model (This file
    contains the geoid data). The left-hand pane would be automatically posi-
    tioned on the Temp folder where this file would have temporarily been stored.

    locate this file,then copy to your sd
    usually it is in "c:\users\yourpc\appdata\local\temp" directory, you have to set your folders to show hidden folders and files, congrats to your recent publication.

  • download gnss solution v 3.10.10 from magellan ftp site there's some tools there called geoid that helps me get my gsf for my area here in ksa. i wish this will help gary. God bless, happy GPSing.
    • here is about 150 mile radius or rectangle that I need the geoid09a.gsf file for:

      geoid09 desired upper left 38.239258°/-98.967784°
      geoid09 desired lower right corner 33.936713°/-92.557037°
      therefore the upper right would be 38.239258°/-92.557037°
      and the lower left would be 33.936713°/-98.967784°

      See the Google Earth placemarks attached below this post. My office is at 36.120632°/-96.145900°
    • I have downloaded it. Just like the past versions, it will create a custom file but not convert the geo to the gsf according to the manual and there is no instructions on how to physically create the file so I can put it on the SD then activate it in the units. I ran out of time to play with it and since the old program works great, I have not bothered to rock the boat, LOL. I tried the previous update and was not happy with it. So I am running two versions back. To be safe, someday I will try to install and play with the new one on my other computer so I will not mess up my working programs. Like I said, I have all the updates stored in my "installation files" folder for the newest version.
    • I agree Gary wise move not to dis rupte the money maker! :) When I hit the lottery so to speak I ntend to have a systme fully integrated to just handle the "Frontline" programing. Until them its safety first. Just launched my GPS Business, Called beyond Measure. So far so good.
