Removing GPS chip

[diggityz]

I was wondering if its possible to completely remove the GPS from this unit? I use a external one and they the built in one interferes with it.

Does turning off the internal GPS not work?

From what i understand the GPS toggle doesn't turn off gps, it only tells the system to allow apps access or not

Airplane mode will completely disable the GPS receiver unless it receives a E911 transmission or you re-enable it.

GPS does not transmit, it only receives the signals from the satellites. Therefore, it is not possible that it is the gps chip in the Nexus that is interfering with your external gps device.

That's incorrect. Being unable to toggle off GPS would be an unnecessary drain on your battery.

He might not mean interfere in that sense. I think he means that the Nexus 7 is using the internal GPS data instead of the external device data.

Try listening to an ipod on an airline during take off. When they say to turn it off, refuse and argue that it's not possible for your ipod to interfere because it doesn't transmit.

Post video on youtube.

What's wrong with the internal GPS that makes you want to use an external one?

 

[diggityz]

The internal one is not very good, for what I need it for, I need pinpoint coords, thats why I use an external GPS. Regardless of my reasons Id still like to know if anyone has experience removing GPS chips from tablets and could assist me in doing so.

I'm not an expert, but that level of surgery is likely to mess up something that's critical. My fear would be that the GPS chip is integrated with other necessary components, like WiFi or Bluetooth. Isn't it part of the whole SOC? Curious about this.

I think when I was on cm9 on my old epic touch there was a setting in locations that allowed me to use either the phone's GPS or an external one. Maybe check and see if that is present in cm10 for the nexus 7

You try searching in the play store for an app that would allow this?

I just tested my own Bluetooth GPS module and it worked. Here are the steps.

1. Pair your GPS module (obviously).
2. Disable the internal GPS.
3. Enable "Allow mock locations" in developer settings.
4. Install "Bluetooth GPS" from the Play Store.
5. In Bluetooth GPS, connect to your GPS module and "Enable Mock GPS Provider".
6. ?
7. Profit!

If you need alter your device in such a way then the Nexus 7 might not be for you

The GPS receiver is not responsible for accuracy.

The original GPS design contains two ranging codes: the Coarse/Acquisition (C/A) code, which is freely available to the public, and the restricted Precision (P) code, usually reserved for military applications.

C/A codes are only accurate to 30 yards. P codes are accurate to about 7 yards. More expensive GPS units use algorithms to predict your position more accurately but are really just guessing.

If you actually remove the GPS chip the Nexus 7 will not boot. Unless you can create your own ROM to skip the hardware check process.

Hey Einstein, have you ever heard of EMI?

how are your smd rework skills? What do you have for a rework station? If you can't answer that then you shouldn't be messing with it.
