Hi Steve,<br>
<br>
FYI, I got an alert early this morning of a possible flatbed...
1:52am. Unfortunately, I didn't have the logging running, but it is
perhaps interesting that I had gone to bed less than an hour before
(was out playing with the telescope until after 1am). <br>

<pre wrap="">Greg,
Attached are graphs of your data. gregd.all.png shows all of the
data, and gregd.peak.png is the highest distance deviation of 369
meters, which is less than the default 500 meter threshold.
It looks like there is a diurnal pattern to the data with increased
deviations around midnight local time (the X axis times are UTC).
It also looks like your home elevation must be about 380 meters since
the altitude variable drops down to negative that amount frequently,
which would occur when that value is taken as zero (there is a special
case in the code to treat some values as zero).
I tried overlaying my data and yours, but there seems to be no
correlation between the peaks in my data and the peaks in yours.
Interestingly, my data does not show a similar diurnal pattern.

<pre wrap="">Thanks. For me, today's log was much quieter. The maximum excursion
was 115 meters and it was roughly coincident with loss of lock.

<pre wrap="">Ok. I'll let it run for a few days and see what happens. Not planning to drive the car until next week.

Nothing gets written (or at least the file size as reported is not
updated) until the recording is stopped with "can log off".
