示例1: test_appendix_c_satellite
# 需要导入模块: from skyfield.timelib import JulianDate [as 别名]
# 或者: from skyfield.timelib.JulianDate import ut1 [as 别名]
def test_appendix_c_satellite():
lines = appendix_c_example.splitlines()
sat = EarthSatellite(lines, earth)
jd_epoch = sat._sgp4_satellite.jdsatepoch
three_days_later = jd_epoch + 3.0
jd = JulianDate(tt=three_days_later)
jd.ut1 = array(three_days_later)
# First, a crucial sanity check (which is, technically, a test of
# the `sgp4` package and not of Skyfield): are the right coordinates
# being produced by our Python SGP4 propagator for this satellite?
