thank you very much

thanks for the reply, the height is 408km but i am not sure how to work this out

Hi, I was wondering if anyone could help our team with this question as we have got into stage two of the Astro Pi competition. What area of ground coverage would we get from a single photo taken from the ISS? We would like to have photos of the entire flight path and we need to know how often to ta...

Thanks for the help I have isolated and speed up the segment of code now it is super fast.
