Locate Satellite at the time of TLE

ghost commented 5 years ago

Hi, I was wondering about the way how can I get the location of a satellite at the time of it's TLE? (i.e. I am not interested in modelling the orbital trajectory, rather just the location when the TLE was recorded. Thanks.

Hi Eric,

I tried to run the examples on that repository but I could not.

Hi @MomoTavashttps://github.com/MomoTavas have you tried existing solutions such as https://github.com/pytroll/pyorbital ?

Poking this thread for the benefit of future readers. Can someone correct me if I'm wrong?

I understand this can be achieved by just passing in a timestamp to the observe() method. If this is supported as shown below, can we close this issue?

>>> qth = (37.771034, 122.413815, 7)
>>> tle = """

>>> sat = predict.observe(tle.strip(), qth, 1488873372.0)
>>> print(sat.get('latitude'), sat.get('longitude'))
