I guess it would be a valid ask to parse that block in the Canadian
*.sum file too for height
OHT SYST MODEL HEIGHT OHT CGVD2013 CGG2013a 362.7005 What's your take? I
can incorporate this into the reporting no problem. Hope this is
sufficient information to answer your question :) Mahalo, Werner

This thread had me inspired to the point to create a Jupyter notebook
which gathers the *.sum files from some folder calculates a Weighted
Average Position and does three plots with Horzontal offset, Vertical
offset and ENU offsets over sessions. I have one 'runaway' take which
is horizontally off by 40mm, all else looks pretty ok to me.
I live on a volcano. I see much greater than 40 mm offsets in the
sidewalks around my house from year to year.
Can you be more specific about "height". gpsd reports two types of
"height". Altitude MSL (altMSL) and Altitude Hgeight Above Ellipsoid
(altHAE). altMSL is very sensitive to the date of your gravity model.
altHAE is much less sensitive, but does seem to change yearly or so.
Please find attached the notebook as ipynb and the output as PDF.
Pretty neat data presentation. Thanks!
