Python script to dump some ISS orbit data

iss-orbit-data.py

#!/bin/python

import math
from pyorbital.orbital import Orbital
from pyorbital import tlefile
from datetime import datetime
from datetime import timedelta

tle = tlefile.read('ISS (Zarya)', 'C:\sankar\personal\iss-tle.txt')
orb = Orbital('ISS (Zarya)')

year = 2018
month = 3
day = 9
hour = 0
minute = 0

time = datetime(year, month, day, hour, minute)
delta = timedelta(seconds = 60)

for i in range(300):
	(x, y, z) = orb.get_position(time)[0]
	r = math.sqrt(x*x + y*y + z*z) * 6378.1
	longlatalt = orb.get_lonlatalt(time)
	print time, ',', longlatalt[0], ',', longlatalt[1], ',', longlatalt[2], ',', r
	time += delta

Hi Sankaranarayanan,
Would it be possible to show (or attach) your sample TLE (iss-tle.txt) file format?

Is it something like this:
[http://www.celestrak.com/NORAD/elements/gp.php?CATNR=25544](url)
or it's got multiple entries for different timestamps in the same file?

Thanks,
Paddy

Hi, Paddy -

It's exactly like the example you have quoted. PyOrbital doc is here - https://pyorbital.readthedocs.io/en/latest/
