Thread: About 37xx converted to 34xx satellites reception accuracy

Loly, I decided to be the guinea pig in our "lab", lol .. but before I was careful to backup the region 139.
Now the part number appears on "supported_features.html" file (is "part number" of what?)
I tested before and after the alteration and the best accuracy was 4 meters. I also tried with the option "predicted eph and cold start", but the best result was also 4 meters (static measurement, open sky, almost cloudless, 10/11 satellites). It would then be a good result? I think not. First because it is a static measurement and the most important is the dynamic, beyond what many factors can influence the accuracy. Second, because I believe that only with a 3790 original side by side we can be assured of installed implements.
Supposition? Not so much .. Yesterday I made a comparative test, static and dynamic, between my 3790 and a modified 3790 original, with and without "cold start" .. and the results were always worse values ​​for the 3790 modified, ranging from 40% (static) to over 200% or more in motion, always with both side by side. Before the alteration of the region 139 nothing was done and still I obtained 4 meters today, which seems to be just a more favorable condition of the day and location. As after the alteration of 139 rgn I obtained 4 meters too, so I can say that nothing has changed in relation to the measurement more careful what I did previously. I have video and screenshots and publish here until tomorrow..
Anyway let's collaborate to the extent of our possibilities for the solution of the problem. Loly, its initiatives are great and we just have to thank you for your collaborative and selfless effort.
Beyond the question of correct fixation of Ephemerides by the 3490 firmware in the hardware of 3790, I still believe that the issue of imprecision also has to do with the a constant of correction or the own algorithm itself, in the two different firmwares. Knowing where this algorithm and how to change it, even if for just insert the constant, is a task for the few, so we rely on you and whoever else wants to collaborate, of course
