how to locate someone in case of an abduction - GSM-Forum

execn · 07-10-2011, 00:24

i need to be able to locate my children in case of an abduction.there was such an incident nearby which made me worry.In case of an abduction the tracking unit need to be able to work inside a car trunk with many buildings around.Ability to work with obstacles is the most important parameter for me.I searched google and find lots of gps tracking devices but i dont know which one is able to do this.

I would hide a mobile phone to my childrens backpack as gsm signals can be tracked indoors and in car by police but turned out to be too inaccurate (500m to kms).

I would ask

1-if i use a mobile phone with a bluetooth gps module and tracking software can i accomplish this

2-i read agps uses gsm signals where gps is unavailable but how is accuracy and ability work inside a car trunk

3-is there any tracking device which can accomplish this

4-is there another solution

i can pay max 200$

You get personal GPS tracker for persons and pets on Ebay or in special stores.
They usually contain a GPS module and a slot for a GSM card.
If you want to know where the pet/person is you send a SMS and get the coordinates back as an SMS.
More expensive models can be actively tracked on a computer once activated by phoncall/SMS.
Inside a trunk nothing will work as there is neither phone nor GPS reception, but as soon as the tracker gets out it works normal again.

One of the low end modelswith good functions would be this.
Do a bit of research and you will find other models with differnt functions and features.
Hope that helps you a bit....
