changing the AMU thresholds to 2.0 as suggested by Warren fixed the
problem, the unit is now working properly, thanks much for the hint. And
no, this
was not obvious to me.
Hi Said
Just out of interest, what levels of AMU are you seeing reported?
According to Trimble's Thunderbolt Monitor version 2.6 the six satellites
I'm tracking right now are showing AMU values of over 40 and another stops
tracking when its AMU drops to approx 33 but starts tracking again at a
reported AMU of approx 36 to 37.
My signal level mask is set to 4.0, and I don't seem to have had any
problems because of that, but I'm intrigued as to the actual relationship
between the quantity described as the signal level mask and the reported AMU
levels.
I would have assumed the units to be the same but that doesn't seem to be
the case.
OK, so I've just dropped the threshold to 2.0 and am now tracking eight
satellites, with the reported levels for the one mentioned above still varying
as before and another just below 30 with neither dropping out, but I'm
still non the wiser as to the actual value of the set threshold in terms of
the reported AMU levels.
