The trajectory computation has been updated and will be valid until 15th January

This tool calculates the elevation, azimuth and range of the satellite for the nominal computed trajectory from an observer position. When satellite is not visible, no records are returned.

Computation may take several seconds. After the computation finishes (table is shown) please click on “Select table” button to select the table records and copy the text to clipboard (cmd/ctrl-c).
