Limitations
  • I do not have full scanner parameters for the RESURS and METEOR satellites, so ground tracks are based on my best estimates comparing with actual received pictures.
  • It seems that RESURS may not scan quite symmetrically with a southbound image being centred a little further west than the predicted ground path.
  • The program displays most dates and times in UTC

    Setting your computer to UTC for WXSat

    If you wish to run WXSat to collect wave files with the correct UTC times as filenames, I recommend the following procedure.  This is not required simply to use WXtrack.  Within WXtrack, the system time is extracted as UTC using the GetSystemTime function built into Windows itself, and the program should display UTC correctly however your Time Zone and Daylight Savings are set.

    Follow this procedure only if you wish to make WXSat record filenames in UTC.

    Start button, Settings, Control Panel, Date/Time.  Choose the Time Zone tab.  Ensure that the time zone is set to GMT, and that the "Automatically adjust clock for daylight saving changes" is unchecked.  (The screen shot is from Windows NT 4).



    But I can't set my computer to GMT...

    Note that on some Windows 98 PCs there have been reports that even though the "automatically adjust ..." checkbox is unchecked, Windows still behaves as if it is checked!  Do not despair!  There is a tiny utility in the Windows 95 Kernel Toys called TZEdit (Time Zone Editor) which does behave correctly, and additionally allows you to set other elements of a .  The utility appears to run under Windows NT and 98, as well as Windows 95.  You may find the full set of Kernel Toys on the Microsoft site or magazine cover CD as "KRNLTOYS.EXE".  If you can't find this file, e-mail me and I will see if I can help.
