I don't believe, or see how, the operating system could have anything to do with the LS running slower acquiring fixes. Yes, I too, like Nate saw Topcon and other equipment preform slower after months (if not a year or two) between firmware updates, but that was almost always to do with the tracking and the alignment of the satellites being out of sync - we don't have that problem with the Javad equipment.
What we've been seeing, unfortunately, is just very, very tough conditions with what everyone has described. Low cloud cover, wet leaves, lots of rain, high humidity,etc. all make a considerable difference in RTK performance in canopy.
Time and time again, we've been in a horrible spot or farm and get nothing - decide to call it quits or move to a different part of the job - return the next day and - boom - works like a beast. So many factors go into it working in heavy canopy, it's really impossible most times to put your finger on exactly what is causing it to be slow.
I am definitely as impatient as anyone, but I try and remind myself on these frustrating and difficult spots "well, if the LS can't get this, I'm sure glad I'm not trying to get it with another brand of equipment"
The worst of summer is hopefully over, leaves will be falling soon and when (crosses fingers) Galileo finally gets here, I firmly believe we will see an entirely new world in heavy canopy next summer!
