[Lunar-Interoperability-Forum] Lunar Interoperability Forum Short talk proposal

[Marshall Eubanks]

In the call for this meeting, it says:

If you wish to submit a proposal for a short talk during the forum please
contact *Lunar-Interoperability-Forum at mailman.ccsds.org
<Lunar-Interoperability-Forum at mailman.ccsds.org>*.

So I am doing that here.

Regards
Marshall Eubanks

The new lunar position, navigation and timing reference system

T. M. Eubanks, Space Initiatives Inc

The lunar PNT system is currently tied to the terrestrial reference system,
specifically the ICRF, the IRTF and Earth rotation monitoring under the
IERS (the author helped to initiate all three of these efforts). However,
in the longer term this reference system maintenance will be transferred to
the lunar surface and lunar orbit, both because that is where it is needed,
and because the Moon is dynamically quieter than the Earth, without our
planet's atmospheric and ocean currents.

While the Moon is dynamically quieter than the Earth, it is not totally
static, with meter-level irregular motions over year and  multi-year
periods. Development of the lunar reference system thus requires improved
monitoring of lunar surface and whole-body dynamics; the new lunar PNT
system will be both a scientific, and an engineering, effort.

Making this lunar PNT reference system widely available will require
interoperable navigation beacons, such as the interoperable wide band
continuum COMPASS beacons we are developing, lunar geodetic satellites, and
also a common reference frame standard, such as was developed for the Earth
by the IERS in the 1980’s and afterwards.
