Vehicle mounted DA1 with Catalyst

We are trying to use Catalyst with the DA1 mounted to the roof of a car and are seeing a fairly regular accuracy reduction over time.  Startup is OK with the precision subscription (approx 3cm) but as we move the vehicle this degrades to 30cm after approx 10mins and down to 50cm after another 10mins, finishing at approx. 70cm after 30mins.  The vehicle is moving slowly (20-30mph) around areas with no tall buildings so signal loss was not really an issue.  Start and end point at the same position (it's a loop) and total distance approx 10km.  Has anyone tried the same sort of thing?  We wanted to try and understand why there is regular accuracy loss.
