dsgp4.omm.OMM#

class dsgp4.omm.OMM(data)#

This class constructs an OMM (i.e. Orbit Mean-Elements Message) object from a string containing a single message (in JSON, XML, KVN or CSV format), from a dictionary of OMM fields, or from a dictionary of elements (i.e. the same dictionary accepted by dsgp4.tle.TLE).

Since an OMM carries the same SGP4 mean elements of a TLE, the resulting object can be used everywhere a dsgp4.tle.TLE object is expected. Contrarily to a TLE, though, it is not constrained by the two fixed-width lines: objects whose catalog number is above 339999 (i.e. beyond what the Alpha-5 convention can encode) can only be represented as OMMs.

Parameters:#

data (str, dict): OMM data

Returns:#

dsgp4.omm.OMM object

__init__(data)#

Methods

__init__(data)

apogee_alt([R_eq])

This function returns the apogee altitude of a given TLE.

copy()

This function returns a copy of the TLE object.

perigee_alt([R_eq])

This function returns the perigee altitude of a given TLE.

set_time(date_mjd)

This function sets the epoch of the TLE to the given date.

to_omm()

This function returns the OMM (i.e. CCSDS Orbit Mean-Elements Message) representation of the TLE object.

to_tle()

This function returns the TLE representation of the OMM object.

update(tle_data)

This function updates the TLE object with the given data.
