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.
$ pip install odmpy
import odmpy.opm as opm

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)
