I am a long-time user of Orange GPS-Trace and I really love it. I have a tracker device in my car, so here is a feature proposal that is really missing from the Orange system:
How about implementing a tracker-jamming notification so that tracking-device can also be used as a security-device? We all know that GPS/GPRS jammers are really cheap these days, and in order to use the car-tracker as a security-device it should be able to report jamming.
Example: I set my device to report every 5 minutes to the Orange server. If the server does not receive new data from my device in 5+(5/2) minutes it should send me a notification to e-mail (or SMS) telling me that my device is offline, probably because it is jammed by thiefs in their attempt to steal the vehicle.
What do you think?
