Hello If you read French, you can have a look on: http://members.aol.com/marionjc/eurosat/homepage.htm When downloaded, this windows tracking program can run in English,Spanish, Italian or French language and can be put in the automatic launch menu. All internet .tle files are read and the first alphabetic file is automaticly launched. If it's alldat.tle you have more than 8000 sat simultaneously tracked on a world map and on two views of the local planetarium with 'boilerplate' objects (stars sun moon and planets) and Earth shadow. Each output window has it's own pop-up menu with a right click. Predictions output on printable ascii file or printabled graphical windows. An Access database is linked to the program, and, when open, is automaticly(but partialy ) up-dated with new sat which appear in the .tle file. A click on any object on the map or on planetarium windows gives the name of this object, and all infos if the database is open. The program can run also without any sat to perform astronomic views of the skies any where at any date. A windows help (but in french!) is also included. Of coarse, depending the power of the machine, the ability to perform quick calculations if you atempt to view more than 5000 sat simultaneously!
