There are a few ways to do this, but the key thing here is that you're
trying to get MPC to give you a code. So I'd suggest that you go here :

http://www.projectpluto.com/pluto/devel/find_orb.htm

and get the current "in development" Find_Orb. You'll see a list of
changes, one of which is "'Temporary' MPC code (XXX) handled correctly".
At some point, that section links to MPC's bit about "the observation
format requires an observatory code. I don't have a code. How do I
get one?"

http://www.minorplanetcenter.net/iau/info/Astrometry.html#HowObsCode

MPC handles this by asking that you use the temporary code XXX. You
put your latitude/longitude/altitude in as a comment line; they give
an example :

COM Long. 239 18 45 E, Lat. 33 54 11 N, Alt. 100m, Google Earth

MPC has long recognized this method of dealing with an "uncoded"
location. Find_Orb now does so as well.

Note that you _can_ just make up your own code and put it into
'rovers.txt'. But MPC will have no idea what you're talking about.
