I found a big gps performance gain on reborn, cm9 and gingerrom. As a service tech, I drive upwards of 180 miles a day (as little as 40 miles, too). I make between 8 and 12 stops. I use the gps intensely. I really see a BIG difference.

Also, I found that the routing was vastly improved when I added those two files to /data/gps. But, to be fair, it was also around the same time that Google updated Maps.
?
One file, gps.conf, should be in /system/etc and two files , secgps.conf and lto.dat, should be in /data/gps.
Hm. Maps locks on fine, but when I try to check in to locations on 4sq, it throws an "invalid geo coordinates" error. Yelp doesn't seem to like the GPS output it gets, either. Any ideas?

I don't use 4sq, but I have no problems with FB and G+ getting a lock on me. Do you have wifi locations turned on?
No, no wi-fi locations. I don't like the associated battery drain. I just use GPS.
May just return to defaults.

I don't think there's a perceptible difference using wifi locations when gps and 3g are also on.
Wifi polls even when you're not running an app that calls for it (which Google admits when you turn the wifi option on, in ICS at least). GPS only turns on when required by an app.
Hm, I didn't report my final findings here. Oops.
SO! GPS never worked with any of my apps aside from Maps, and generally borked location output even with wifi service on. I tried to flash the "return to stock" zip and it seemed to install correctly, but didn't fix the output issue. In the end, I re-flashed the ROM and kernel I was using; only that made GPS work again across the board.
Haven't tried it on the latest ROM I'm using. Not likely to. I'm glad it works for others.

I'm sorry it didn't work for you. You can try just changing the NTP_SERVER and add three more lines to the /system/etc/gps.conf in thekravens a10:
Those will make the gps use the four time clocks closest to you for a faster lock.
Other than that, I have no idea why yours didn't work.
Code:
NTP_SERVER=0.north-america.pool.ntp.org
NTP_SERVER=1.north-america.pool.ntp.org
NTP_SERVER=2.north-america.pool.ntp.org
NTP_SERVER=3.north-america.pool.ntp.orgThose will make the gps use the four time clocks closest to you for a faster lock.
Other than that, I have no idea why yours didn't work.
Thanks. I really have no idea, either, especially when I seem to be an isolated case. I may give those changes a shot.
