Wow, I was not aware of that site. Thanks for sharing it, Stan!

BTW, I mislaid my O-GPS1 manual a couple of months ago and needed to do a web
search to find a copy (since Pentax does not offer a pdf download). One of the
pages that showed up in my searches was:

OK, based on very limited testing, it looks like I was wrong. GPS on camera A.
Turned on camera, then the GPS unit. Calibrated (calibration OK reported almost
immediately, before hardly any camera rotation). Stepped outside; the blue
light blinked in "search" mode for a couple of minutes before

I forgot about that :) I reset my phones "A-GPS XTRA" data and it did
take a lot longer to lock from a "cold start", probably not much
quicker than the O-GPS1. I don't have cell location turned on on my
phone but a couple of my apps that use GPS download the AGPS data on

Good explanation, Matthew. I suppose that means that systems that can
take advantage of the GROUND-BASED WAAS stations should perform a bit
better on the elevation question because you have another point to
calculate the triangulation/time measurements from. I have to believe
that you would need a

On the subject of research, it appears that we have a bit of a GPS
accuracy advantage in North America.
This 2004 PDF explains 4 methods of correcting GPS data (and also 6
sources of error).

Interesting Matthew. I had not heard that before.
Pure conjecture on my part: Is it possible that this is what the unit
is doing that drains the batteries, even when "off"?
If so, it still probably couldn't get the data from inside the house.
I wonder if it would be a good idea to keep it on the d

Getting a fast GPS lock depends on having up-to-date eph
There is an official Pentax video on the cal procedure somewhere, I
will try to find the link. My advice would be to do the cal then the
fine cal for the astro function on site and make sure that you are
well away from the car or other magnetic objects as they will affect
the accuracy of the compas
Yes, I've read about the battery issue. It sounds like it draws
battery even when it is off. I've got rechargable AAAs, so I will just
plan on starting with a full charge any time I plan on using it. I
haven't heard anybody say that they run out before a night's session.
I have a theory that the "

I'm embarrassed to say that I have YET to even try out my O-GPS1,
which I purchased mainly for the AstroTracer functionality. Life has
been a little disrupted, but is getting back to "nominal" (as NASA
likes to say during their spacecraft launches).
I now have an even greater incentive to get ON I
