Hi Mark,
Thanks for a great product. Could you please help me understand if the alamanac data is stored somewhere on the RPi or on the BrrryModule. I see that ephemeris is stored for 4 hours but is alamanac stored somehwere? With my BerryGPS v3 at times I get a quick fix and sometimes there is a delayed fix from the same location. There are slight variations in weather but I am not able to pinpoint the difference in performance.

Different times of day can change the time to fix as the satellites would be in different postilionsMark --OzzMaker.com --

Thanks for the quick reply. I figured also hat different times could influence but its was the general behavior over time I was mentioning. So I read that ephemeris data is stored in the RAM for 4 hours with the help of SuperCap. So the entire almanac when obtained is also stored or to save space the almanac is just forgotten?
Regards
