And how do you know that this "fix" doesn't work at all? I'm not being sarcastic, I just really want to know what info you have that this doesn't do anything.
Excellent question!
Without going too much into gps/a-gps/almanac/ephemeris/ntp/supl/wiper (more than enough info can be found via google or search on xda) and how they fit together. Suffice to say that by looking at the stock gps.conf file you can tell that the Triumph had already included all the known A-gps ?tweaks?. I trust you have looked at the stock gps.conf file on your T and have compared it to the supposed ?fix,? and have noticed the only change was a modification to use the ntp.org server instead of gpsonextra.net server as time source?
In the simplest term, NTP provides a highly accurate time to your phone. along with other A-GPS info, NTP helps GPS to ?cheat? by skipping through the slow process of downloading data from individual Satellites. This tweak had dramatic effect on some of the older phones with mis-configed A-GPS but only because those phones did not have any time source defined.
The stock Triumph gps.conf uses xtra1.gpsonextra.net as its ntp server. Gpsonextra is a server pool hosted by Qualcomm specifically to provide A-GPS services to phones. ntp.org is a general time source that is used by everything from aircrafts to desktop computers. their serves are divided into different pools based on geographic region in order to reduce latency. us.pool.ntp.org is one of those pools consisted of servers located in US. Both gpsonextra and ntp time sources are perfectly valid. In fact, from where I am (east cost USA) the ping time to gpsonextra.net was almost half of us.pool.ntp.org. so in theory, I would have gotten a more accurate time from gpsonextra instead of ntp.org.
to answer your question, I know this ?fix? is no magic not only because I know what it really does but also because I have already tried many known gps.conf tweaks on my own Triumph, including changes to use ntp.org. they did absolutely nothing to make the gps work any better.
Then again, like I said, this is such a small change it would not hurt your phone in anyway. there?s no reason not to try it. And for those who seem to think this ?fix? had magically given them a working GPS, I suggest as a sanity test, put the original ntp server back and see if you can notice any real difference.
