Hint - Compare algorithms.
This is an interesting and educational exercise. Select one satellite
element set. Generate 2 more windows with
Change the algorithms in the new windows using the
menu in each Map Window. Choose
in the Main Window, and then
This will set the time to the
All algorithms should give virtually the same results for this time. Now step
forward or back and see how long it takes for the predictions to diverge.
Change the step size (
if things are changing too slowly.
Add a new window, but this time choose a different element set for the same
satellite (a few weeks earlier or later). Set the time to the reference time
of the later element set. Which of the algorithms does the best job of
predicting the correct position from the earlier elements ?
Repeat the exercise with different satellites. What happens to the predictions
for DOVE ? How about MIR, in a very low orbit ?
