Contents¶
epochType
-
class
sorts.io.ccsds.
epochType
(val1, val2, scale, precision, in_subfmt, out_subfmt, from_jd=False)[source] Bases:
astropy.time.formats.TimeISO
Convert astropy time to “yyyy-dddThh:mm:ss.d->dZ” CCSDS 2.0 epochType standard.
-
property
cache
Return the cache associated with this instance.
-
format_string
(str_fmt, **kwargs) Write time to a string using a given format.
By default, just interprets str_fmt as a format string, but subclasses can add to this.
-
parse_string
(timestr, subfmts) Read time from a single string, using a set of possible formats.
-
property
scale
Time scale
-
set_jds
(val1, val2) Parse the time strings contained in val1 and set jd1, jd2
-
str_kwargs
() Generator that yields a dict of values corresponding to the calendar date and time for the internal JD values.
-
to_value
(parent=None, out_subfmt=None) Return time representation from internal jd1 and jd2 in specified
out_subfmt
.This is the base method that ignores
parent
and uses thevalue
property to compute the output. This is done by temporarily settingself.out_subfmt
and callingself.value
. This is required for legacy Format subclasses prior to astropy 4.0 New code should instead implement the value functionality into_value()
and then make thevalue
property be a simple call toself.to_value()
.- parentobj
Parent ~astropy.time.Time object associated with this ~astropy.time.TimeFormat object
- out_subfmtstr or None
Output subformt (use existing self.out_subfmt if None)
- valuenumpy.array, numpy.ma.array
Array or masked array of formatted time representation values
-
property
Functions

read_oem
(fname, xml=True)[source] Todo: docstring
-
sorts.io.ccsds.
read_tdm
(fname, xml=True)[source] Just get the range data # TODO: the rest
# TODO: Document function. # TODO: Update plain text function to be more general and conform to CCSDS 2.0
-
sorts.io.ccsds.
write_oem
(t, state, meta, fname=None, xml=True)[source] Uses a series of astropy times and state vectors to create a CCSDS OEM file (plain-text of xml) or return a string.
- Parameters
t (astropy.Time) – Vector of unix-times
state (numpy.ndarray) – 6-D states given in SI units in the ITRF2000 frame. Rows correspond to different states and columns to dimensions.
meta (dict) – Dict containing all the standard CCSDS 2.0 meta data.
xml (bool) – If False, use the plain-text format
fname (str) – Output file-path for OEM.

write_tdm

-
