Satelite Fix for GPS.

[Guest Akash P]

Requirements:

Rooted Device

File Manager: e.g. Root Explorer

1. Searching for NTP server information:

Go to http://www.pool.ntp.org/en/

At the right side of webpage, there is "Active Servers". Go in and look for the setting of your 1)region and 2)country

For example, one's region is Europe then you write down the NTP server for that: 0.europe.pool.ntp.org; 1.europe.pool.ntp.org; 2.europe.pool.ntp.org; 3.europe.pool.ntp.org

Then the servers for your country from the list down there and click the link(Example: Switzerland — ch.pool.ntp.org; 0.ch.pool.ntp.org; 1.ch.pool.ntp.org; 2.ch.pool.ntp.org; 3.ch.pool.ntp.org

The "Italic" words are the information you need to jot down for later use

2. Modify the gps.conf file:

Copy the codes to a notepad, then change the extension name from .txt to .conf then copy to your phone

Use file manager to copy to this location: /etc/gps.conf and replace the original gps.conf

Open and Edit the gps.conf using rootexplorer or others file managers

Change the COUNTRY and REGION in following lines with the info you got from the website just now. Keep other values unchange unless you know what it is. Example of REGION such as NorthAmerica, Asia, Africa, Europe.

Your new gps.conf should look as below:

NTP_SERVER=COUNTRY.pool.ntp.org

NTP_SERVER=0.COUNTRY.pool.ntp.org

NTP_SERVER=1.COUNTRY.pool.ntp.org

NTP_SERVER=2.COUNTRY.pool.ntp.org

NTP_SERVER=3.COUNTRY.pool.ntp.org

NTP_SERVER=0.REGION.pool.ntp.org

NTP_SERVER=1.REGION.pool.ntp.org

NTP_SERVER=2.REGION.pool.ntp.org

NTP_SERVER=3.REGION.pool.ntp.org

XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin

XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin

XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin

# DEBUG LEVELS: 0 - none, 1 - Error, 2 - Warning, 3 - Info

# 4 - Debug, 5 - Verbose

DEBUG_LEVEL =0

# Intermediate position report, 1=enable, 0=disable

INTERMEDIATE_POS=0

# Accuracy threshold for intermediate positions

# less accurate positions are ignored, 0 for passing all positions

ACCURACY_THRES=0

# Report supl ref location as position, 1=enable, 0=disable

REPORT_POSITION_USE_SUPL_REFLOC=1

# Wiper (wifi positioning), 1=enable, 0=disable

ENABLE_WIPER=1

##### AGPS server settings #####

# FOR SUPL SUPPORT, set the following

SUPL_HOST=supl.google.com

SUPL_PORT=7276

SUPL_NO_SECURE_PORT=3425

SUPL_SECURE_PORT=7275

SUPL_TLS_HOST=FQDN

SUPL_TLS_CERT=/etc/SuplRootCert

# FOR C2K PDE SUPPORT, set the following

C2K_HOST=c2k.pde.com

C2K_PORT=1234

CURRENT_CARRIER=common

DEFAULT_AGPS_ENABLE=TRUE

DEFAULT_SSL_ENABLE=FALSE

# TRUE for "User Plane", FALSE for "Control Plane"

DEFAULT_USER_PLANE=TRUE

Make sure the permission of the file is rw-r--r--

4. Reboot:

Go setting, turn on your "use GPS satelites"

Restart the device (normal restart)

5. Use GPS status and Toolbox: Market Link

Tool available in market for free.

Open app> tools> manage A-GPS state>Reset

Open app> tools> manage A-GPS state>Download

Optional restart device (not compulsory)

Use GPS status to start fixing satelites

Your satelite fixing speed should VERY FAST now

After get a successul GPS Lock, open your GPS applications and use like normal (e.g. Copilot, Sygic, or TomTom)

Extra Suggestion: Please make sure your GPS is enabled before your device is turnoff or restart. It won't actually use GPS unless you open map-related app or google.com.

CAUTION!!!: DO NOT use fasterfix after this. It will overwrite all the content in gps.conf.

What exactly does this do? Will it work in India?

What exactly does this do? Will it work in India?

1. It speeds up satellite fix (GPS positioning).

2. Yes, it will work wherever you live.

or you can use the CWM patch from here.
