Not to state the obvious to agressively, but did ya'll google on
HDOP?

Which lead to an interesting Trimble site:

Given a very cursory scan of links, I saw several reference to
meters, so your assumption it is a reading in meters is commonly
held, but I did not find an authorative reference to it actually
being interpreted as meters.
