GPS problem- Problem Fixed.

[#1]

Recently, i found my GPS didn't work. i connect SK17i with mobile network and use google map.The best result is 1400m range.It doesn't matter how long you stay outdoor, the GPS icon always twinke and couldn't find any sattelite. But in the same position and same phone setting when i use LT18i, it found sattelite in 10 second.  Is it possible to solve this or not? Firmware problem?

Hi All,

First of all I want to thank you all for the information that we've received. Right now I think that we have all the information that we need to solve the problem.

I'll try to explain more about what is causing this so that you can find ways of avoiding it while wating for it to be fully solved.

There are certain information that the GPS receiver needs to function optimally:

     1. GPS time (which is known if you have a GPS fix)

     2. Rough location estimate (which is known if you have a GPS fix)

     3. Detailed information about satellite orbits called Ephemeris (which is decoded from each satellite above the horizon and takes about 30 seconds per satellite)

     4. Rough information about satellite orbits called Almanac (which only needs to be decoded from one satellite and takes about 12 minutes)

To get this information quicker than decoding if from the satellites we try to download it from a server over the Internet.

Every 5 minutes the GPS receiver checks if any information is missing. Even if you have a GPS fix the almanac might be missing and a connection attempt will be triggered.

So what you should do is to make sure that you already have all the info that the GPS receiver might need.

One way of doing so is to let the GPS receiver run for about 20 minutes in good signal conditions to decode the Ephemeris and Almanac from the satellites.

An other way of doing it is to download the data from the server while on WiFi connection. When the data downloaded from the server becomes stale you will need to decode it from the satellites or update it over a WiFi connection or you will start loosing the GPS fix again.

To force the data to be downloaded you should install an application that calls the LocationManager.sendExtraCommand("gps", "force_xtra_injection", null) method while on a WiFi network.

Thank you uliwooly!

i read this thread again carefully.

What news for my Mini Pro were:

I did all as Oskar said, but nothing happened. My phone still can't fix any satellite.

So I thought that might be some problem of Android 2.3. I wait for the Android 4.0. Two week ago, I updated the phone to 4.0. My phone still can’t fix any satellite.

So I thought that really be hardware problem. The day before yesterday, I brought my Mini Pro to the service center HK. They check and told me the hardware is fine and revert my phone back to 2.3 version of Android. My phone still can’t fix any satellite.

Dear Oskar, would you please help?:smileysad:
