Orbit Data Messages

odmpy is a python package for creating valid ASCII OPM, OMM, and OEM files.

Currently, only the orbital parameter message (OPM) module has been implemented.

Installation

$ pip install odmpy

Example

import odmpy.opm as opm
from datetime import datetime

header = opm.Header(originator='NASA')

metadata = opm.Metadata(
    object_name='International Space Station',
    object_id='1998-067A',
    center_name='Earth',
    ref_frame=opm.RefFrame.EME2000,
    time_system=opm.TimeSystem.UTC)

sv = opm.DataBlockStateVector(
    epoch=datetime(2014, 11, 7, 15, 30, 23),
    x=6794,
    y=0,
    z=0,
    x_dot=0,
    y_dot=7.6,
    z_dot=0)

data = opm.Data(state_vector=sv)

iss = opm.Opm(header, metadata, data)

with open('iss.opm', 'w') as f:
    iss.write(f)
