Satellite Time Machine helps you to discover what the satellite was seen in the sky at a particular moment or night .
While it may go back in time to any date, periods greater than one week may have inaccuracies since the application uses the latest orbital elements for calculating the position of the satellites.
To use, simply enter the date and UTC time of observation. Then select the desired satellites category .
As result the map will present the global position of all satellites in the sky while the table shows those who were above the horizon of the chosen locale.
Poin the mouse over any satellite map to know its identity .
By clicking on the satellite over the map or table, the groundtrack is drawed and the selected satellite takes the top of the list .
The city and the timezone of the observer must be properly informed so that the table and the map show the data without errors .
