Dear teqc users,

I have a problem running clockprep on some early files of MTBG (austrian
network).
My understanding is that clockprep crashes when found an epoch like this

I guess that one solution would be to remove observations below 10deg
(which are contained in the original rinex) so that SVs are reduced to < 12.
I tried with teqc with no success.
I would greatly appreciate any suggestion to overcome this problem.

Thanks
