GPS - slow refresh

[juliank]

I tried my Tilt with iGuidance and got very disappointed. The GPS has an issue following my position. It updates the position on average every 30 sec and by the next update I can really get off the quided track.

Other people tell me that something is wrong, as the arrow on the screen should be following me smoothly in real time, not jumping city blocks. The only configurable setting for the GPS is baude rate, but I tried all values and still the same. What could be the problem?

are you in the city with a bunch of tall buildings??
also d/l htc gps and see how many sats your locked on.

I was mostly in the city, but no tall buildings. The GPS can lock me really good and fast, the reception is good, it finds like 8 sattelites. The only problem is it does not stay continuously locked on position, but lockes every 30 sec or so..

I installed the logging tool and will give it a try. Thanks!

What ROM and Radio do you use? stock?

[juliank]

I am using The NoThrills ROM (CE OS 5.2.19170 (Build 19170.1.0.0)), which comes with R 1.58.26.20.

Just tried the HTC GPS tool - not sure what exactly to look for, but it keeps logging very fast, the lines in the logger change at a rate e few per seccond, it always showed 7-8 satellites locked and yet did not update my position in real time, but probably every 30 sec.

If you are using Iguidance 4 then this is a know issues with the GPS chip in the tilt. It will not work right, the only work around is to use a separate bluetooth GPS reciever and not the internal gps. The other way is to use a different GPS software as Iguidannce 4 is the only one that I'm aware of that has this issue....

[juliank]

Yes, I am using iGuidance 4. Where did you see about the issue it has with the Tilt? Can you post some link? I can see only positive feedback. Would be good to know that it is a software issue and not my Tilt.....

Hi, I use miomap. My GPS is not smooth too. I don't need to wait 30 seconds to update the position, but it may need 3 to 4 seconds to update the position. It is not as smooth as tomtom.

Check out a program called GPS Gate. This issue typically has to do with WM6.1 and iGuidance 4.0 not playing well together on the Tilt. GPS Gate reports the GPS feed into something that iGuidance 4.0 can be happy with. Here's another thread for more details...
