Hi
Newbie here. I am thinking of getting Ipaq H4150 with Fortuna: 'Clip-On' Bluetooth GPS receiver (SiRF Xtrac chip) and TTN3.
my question is is it OK to leave the Fortuna permantly powered up? I have a 12V socket in the boot of the car where I want to plug it in to keep the dash clear, but it is permantly on (even when ignition off).
Cheers
Roger |

Technically it is not a problem, but you may consider the following
- your car battery may drain if you leave your car unattended for a longer time (eg. unplug then fortuna in these cases)
- the battery in the Fortuna may get de-calibrated after a while. Make sure you completely discharge it from time to time (use it outside the car) _________________ Lutz

Hi,
I have already done this, I have removed the battery and left the device permanently powered for about two months now without problems. Current consumption (battery removed) is about 90 mA. Unless you have a poor car battery or leave your car for months then you should be fine.
The really nice thing is no TTFF waiting!!
Regards BigH |

Here's a thought:
If you can leave the Fortuna on for long periods and without the battery installed...then if your car was stolen could the GPS unit be traced?
I know that there are websites that do a similar thing for GSM phones e.g.:
www.followus.co.uk
Having just had my car replaced after my old (11 months!) one was stolen then it would be nice to know that this oculd be done by the police - rather than installing an expensive tracking device! _________________ Chris

The GPS unit can't be traced, it is a purely passive receiver. What you need is an active connection somewhere (for example a GSM sender). Some of the higher priced GPS receivers actually do have that, and some of the children's mobile phones come with a built in GPS receiver - same effect. So for example you can send a SMS to the phone asking for the position and would get a SMS back with the data provided by the GPS receiver.
What you do need in any case is a dumb thief/suspect (like this Scott Peterson in the US who didn't notice that the FBI had bugged his car with a GPS logger). Smart bad guys have figured this out long time ago and will not allow tracking/logging to happen. All you need to make the GPS receiver useless is to take the sky view away (remove the antenna, put some metal cover over it etc) _________________ Lutz
