[Q] Bluetooth GPS and Galaxy Tab 2 7"

---

Hi Everyone.

Does anyone tried to use external bluetooth GPS reciever with Galxy Tab 2 7" (P3110) with Bluetooth GPS App from Android market?

Also, do I need root for this app to run?

Marek.

Why use an external GPS when it has GPS built in?

As far as I know it has A-GPS.

Or maybe I'm wrong...

A-GPS is better than GPS. It means GPS plus the ability to lock on quicker using Wifi and cell tower positioning.

"Reliability: Location determined via A-GPS are slightly less accurate than GPS GPS devices can determine location coordinates to within 1 meter accuracy

Cost: It costs money to use A-GPS devices on an ongoing basis because they use mobile network resources. GPS devices communicate directly with satellites for free. There is no cost of operation once the device is paid for."


Checkout last 2 points about Reliability and Costs. As a wifi-only p3113 user, having the ability to connect to GPS sat (even with no internet) would be a HUGE plus. So I would love to know how this bluetooth workaround works!

Have you tried? With wifi off I lock on to GPS in 2 seconds. Offline maps navigation works perfect... what more do you want?

Oh and from Wikipedia...

Assisted GPS, generally abbreviated as A-GPS or aGPS, is a system which can, under certain conditions, improve the startup performance, or time-to-first-fix (TTFF) of a GPS satellite-based positioning system. It is used extensively with GPS-capable cellular phones as its development was accelerated by the U.S. FCC's 911 mandate making the location of a cell phone available to emergency call dispatchers.

Well, instead of buying a GPS, I added some money and got a 7inch tablet P3113 also.

I have no tried offline GPS yet, how accurate is it? does re-direction work? which app would you recommend?

thank you

Accurate enough? Yes redirection works. Google maps has an offline feature. Or you could try navfree.

I love it when people are always confused about A-GPS.
A-GPS is BETTER than just GPS.

Assisted GPS means, that instead of just relying on the GPS satllites, it helps setting the position from WIFI and cell network.
It does NOT cost any money.
It is also handy, when you are indoors, so your device does not get a position fix from GPS satellites.

Besides, this samsung receives the Russian GLONASS satellites in addition to the American GPS, so its very precise.
My 10.1 tab2 (has the same receiver) sees 15+ satellites indoors!
GPS test shows precision down to 1m.
