Hello everyone!
I have a tbolt that I am monitoring with tboltmon.exe and some off-brand 12
channel GPS (I bought from Sure Electronics on eBay) that I am monitoring with
VisualGPS. Both are fed from the same GPS antenna through a symmetricom
splitter. There is a 30 meter difference in the altitude readings between the
two. My tbolt says my altitude (after a self-survey) is ~761 meters and the 12
channel Sure Electronics GPS says my altitude is ~791 meters after 7,500+
readings. I took my hand held Garmin 12XL outside and it says my altitude is
~790 meters at street level.
Anyone have an idea why my tbolt might be reading different from the other two
devices? I am assuming the tbolt is reading low.
Jamie
