Fairy nuff, yes, your plots show the long-term effects. I would like to know what the best time-constant is to use. I appreciate that everyone's will be different, depending on individual characteristics of the Thunderbolts, and also (perhaps more importantly) the aerial and its position. However, I think it would be interesting to at least see the relative differences for one location. I recently learnt that our national mapping organisation (The Ordnance Survey) average the results from their L1/L2 Leica 1200 system receivers, for two hours. Is the oscillator in the Leica significantly worse than that in out Thunderbolts, or could we also benefit from a time-constant of longer than 1000 seconds? I will try to find a quiet rubidium, and do some comparisons against that - the results should, at least, be valid out to a few thousand seconds. I also plan to try reducing the signal level threshold (from the current 4AMU) as recently suggested, and try to see some quantifiable results.
