AlMANAC, gEO AlMANAC, AND CONFIguRATION FIlES

To ensure that each is current, the Almanac, GEO Almanac, and Configuration Files are automatically checked each time
the program is started. If the program finds any of these files to be out of date, it will automatically update the file via the
internet. A provision has been made to update these files manually, if needed.
Manually Updating the Almanac, GEO Almanac, and Configuration Files:
1) From the main WFDE Prediction Program window, select the Help menu (Figure 14).
2) Select the "Update Almanac," "Update GEO Almanac," or "Update Configuration File." The program
automatically searches the internet and downloads the most recent data.
3) A pop-up window appears to confirm that the data has been downloaded. Click the OK button to return to the
WFDE Prediction Program.
4) The file has been updated.
