SATELLITE FIX NEEDED BADLY

PLEASE FIND ME A SATELLITE

I need a fix badly. It has been three days since setting up TT224 on my bluetooth HP4150, including GB map data and GPS209, with a lot of help from this website. I got satellite fix immediately after setting up bluetooth connection using TT Wizard. This was done from inside the house near a window.

That was late at night. The following day when I tried to use system properly for the first time, I got nowhere. GPS status is continuously unreliable and I am starting to get frustrated. I have tried fixing GPS to current location and also leaving stationary for 20 minutes all to no avail. Admittedly I haven't sat stationary in car whilst parked in the road; but I didn't think this was necessary because I had previously got a fix from bedroom. Who wants to sit in a parked car for 12+ minutes just to get GPS fix anyway?

What do I do next? Please help. Embarassed

Scoof.

See if any other program is interfering with the COM port.. And - use something like WinFast Navigator to find out if maybe your GPS receiver went fishing.

Excuse my ignorance as I haven't read any of your previous posts today, but first thing I would suggest is make sure you start acquiring the sats before you start moving. If you have started your journey then you may see delayed fixes up to 40 mins when travelling. The amount of data you need first is best to receive when stationary, once you have your fixes, you only need minimal data to keep the sats fixed so try to sit in the car for 5 mins to start with.

If you still don't get a fix, make sure your car doesn't have a UV coated windscreen. Easy way to tell is to freeze your bo$$ocks off outside for 5 mins, in theory after you've received a first fix on the receiver, you should receive fixes in around 1min from power on.

If that still doesn't work, check out this article as this will walk you through diagnosing your GPS problems and will help you get a better understanding of GPS. Remember GPS is line of sight, although you may have got a fix in your bedroom, it's not the norm!

Thankyou Lutz & Dave for your suggestions. Your comment about stay stationary for about 5 minutes got me thinking Rolling Eyes

. When I received that first fix in bedroom, I was happy and thought that everything would be OK and so I switched off the unit. I didn't really give the receiver sufficient time to establish a proper fix.

So I thought the first thing I would do today before even contemplating your remedies is shut down all running programs, do a soft reset of IPAQ and then run TT Wizard again. It worked!! The GPS status bars came alive and I didn't move until at least six bars were displayed and direction chevron appeared on navigator screen.

I did two journeys and returned home and have now shut down. I am hoping that all will be well tomorrow morning; but for the moment ah feel good! Happy

Because that's probably what your profile says - you can change your time zone there.
