A GPS Web App tracking people

Question

Hi everybody,

i'm inteding to develop a web application that can track somebody carrying a GPS emitter.

I think that the simpliest way is to insert a sim card in the emitter that will send some messages to the databse.

I have some questions: Is there a GPS emitter device that can be tracked by this way (having a sim card reader) and easy to carry?

What's the best architecture to follow? GPS Emitter->database->Spyer Interface ? Other?

Are there devices that can emit coordinates without sending messages or calls?

Thank you,

Regards.

Answer 1

What about smartphones with integrated GPS? You could even use the html5 geolocation API for a simple web based solution.

Answer 2

Thanks for your answer.

I'm more interrested in buying a GPS Emitter. Using smartphones could be useful but i want to avoid that the person access to the device. I want only a box with two or three buttons sending signals or messages for example.

Regards.
