Re: opensource_gps Digest, Vol 37, Issue 2

Here is a white paper from Rakon describing typical TCXO
Requirements for high sensitivity gps applications
(acquisition and tracking).

Might be useful?

Do we have a statistical and system model for the clock? I believe that
we
have to make more studies for the statistical and system clock models
which
will explain some of the problems that you Cliff are having.

I've just updated OSGPS to change the tracking state carrier loop back
to 1
ms update rate.  It was having trouble with cycle slips and I think the
clock is not stable enough to coherently integrate over 20 ms.

Best regards,

Cliff
