Hi

I have an Android app which sends my current latitude and longitude every 3 seconds,

I have another Web application which will mark this latitude and longitude every 3 seconds on Google map. So that i can track the person.

But the location which the application sends is not the exact location. it keeps jumping streets n blocks.

Even when i am driving , it doesn't show exact pathway.

Can any one tell me what might be the issue.

Thanks

How can we tell you the problem without seeing anything you have done?

Could you show the related code?

There are two potential causes.
1. Your doing something wrong, but if you don't give us any sample code we can't help
2. You just don't have a very good signal, and the phone can't get a good lock on your position

You really don't know how GPS works, do you? Start reading these[^].

I consumer electronics, the GPS signal is not as exact as the military version. It's an approximation that is affected by the number of satellites the receiver can "see", effects of atmospheric distortion and interference from "ground clutter".

The last I heard, the current accuracy is somewhere around 50 feet, depending on conditions.

You will never get an "exact" position without upgrades to the current GPS constellation of satellites and receivers.

I don't know. I've never used the Google Maps API. This is when you start reading the documentation to see what the API offers to solve this problem.
