Keplerian Elements
These are data sets needed to predict satellite positions, used by WinOrbit and other programs. [Note to WinOrbit users: be sure to
download the files as TEXT. Unix binary files will cause problems when attempting to import them into the database.] Here are some sources:
Format Converters
Utility programs to simplify conversion of Unix files to DOS format (see the italicized note above!):
Freeware Zip/Unzip software (I used version 5.1 to create the archive file):
Enhanced Data Files
Additional data or updates of files used by WinOrbit:
LATLONG.QTH
- Updated file with the latest DXCC info (June 1997), by
Rob Smith. Ready to use. SPECIAL.QTH
- Same as above, but with all entries
"commented-out". Handy for planning DX contacts - just remove the '*' from one or more entries of interest, and then use for "Show DX" or to print
"Mutual Visibility" tables in WinOrbit. USERMAP0.ZIP
, 16259 bytes) UnZip this to get
the bitmap file, and put it in your WinOrbit directory, before starting the program. This is a monochrome bitmap in blue and green, but the exact
appearance will depend on your software (it's black and white in Paintbrush). The original map is from coastline data such as that available at
the US government National Geophysical Data Center. If you want to make your own map, you can use this as a starting point. If you make really nice map, let me know, and I'll put
it up here for others to share, too.USERMAP.BMP
files:USERMAP1.ZIP
, 143781 bytes) UnZip this to get
the bitmap file, and put it in your WinOrbit directory, before starting the program. The exact appearance may depend on your video driver. It will
look better in WinOrbit 3.0, too. Try the view from space with this. The original map is from the US government National Geophysical Data
Center: http://www.ngdc.noaa.gov/mgg/global/seltopo.html and shows ocean floor relief
as well as land forms. Thanks to Gerard Durand for the suggestion.USERMAP2.ZIP
, 28211 bytes) UnZip this to
get the bitmap file, and put it in your WinOrbit directory, before starting the program. The exact appearance may depend on your video driver.
This is a simplified relief map based on data (coastlines and elevations) from from the US government National
Geophysical Data Center, and is easier to read, as well as having slightly better resolution, than the previous file.USERMAP3.ZIP
, 431949 bytes) UnZip this to get the bitmap file, and put it in your WinOrbit directory, before starting the program.
