Not 100% sure this is the same model, but it would seem to indicate there's a

One thing I want to clarify - it is not a Jupiter GPS module - it
just uses the chipset, presumably hooked up as in the application
info. The board is proprietary, and there seems to be no standard
electrical or operational interface as would be expected in an OEM
GPS module. So, the only way

I opened it up and found a 4 by AA cell battery holder for power, and
a single module that looks pretty proprietary. One side of the module
has a patch antenna, and the other has the brain. I assume there's an
RF board in between, but cannot open it further without possible
damage - the
I peeled open the shield can without too much deformation, so it can
be restored. I found that it's a single board, with the DSP on one
side, and the RF section on the other. It is a Rockwell chipset, with
11577-11 DSP, and 6732-13 RF. On searching I found that this seems to
be called their
I just picked up an old DeLorme Tripmate GPS receiver for cheap, and
am wondering if it can be used for getting a 1 PPS signal. I looked
online a little and found it's pretty common, but didn't see anything
about getting deep into the guts. Most hacks seemed to be about
getting it powered up,
