TimeGPS

class astropy.time.TimeGPS(val1, val2, scale, precision, in_subfmt, out_subfmt, from_jd=False)

Bases: astropy.time.TimeFromEpoch

GPS time: seconds from 1980-01-06 00:00:00 UTC For example, 630720013.0 is midnight on January 1, 2000.

Notes

This implementation is strictly a representation of the number of seconds (including leap seconds) since midnight UTC on 1980-01-06. GPS can also be considered as a time scale which is ahead of TAI by a fixed offset (to within about 100 nanoseconds).

Methods Documentation

set_jds(val1, val2)

Initialize the internal jd1 and jd2 attributes given val1 and val2. For an TimeFromEpoch subclass like TimeUnix these will be floats giving the effective seconds since an epoch time (e.g. 1970-01-01 00:00:00).
