How good is Kaiser GPS?

[bchau]

I believe Kaiser rely on the Qualcomm chip for GPS. How is the performance. People say good thing about the SIRF III chip. How is the Kaiser GPS compare to the SIRF III? Anyone know?

welll in most cases built in gps arnt as reliable as the actuall thing... they are off sometimes

I guess it may depend on what you want/need to do with GPS.

If I turn it on and run Google Maps, it shows me right in the middle of my house, and that's where I am. If I move from one end of my house to another, I again appear in the right place.

To use GPS do we require to have gprs or 3g data activated.
Or is like integrated FM Radion which doesnt require data connection.

No -- there is a GPS receiver built into the unit that sends NMEA 0183 data over a serial port. You'll probably need map software; any software that works with WM6 and a Bluetooth GPS should do the job (e.g. TomTom 6).

I use Googlemaps and TOMTOM 6 with no problem.

I need to mention that I am a current HTC Trinity owner, and if IF if IF if IF the Kaiser has the same A-GPS chip found in the trinity, then this is what we should expect (from my experience with the Trinity)

1- Initial fix time can take long (sometimes it takes 2 minutes, sometimes 5 minutes, sometimes 10 minutes, and sometimes IT NEVER gets a fix and no GPS singal can be found)

2- Once the GPS get a fix, then it works perfectly and flawlessly.

So I only hope that the Kaiser will solve the initial fix problem.

Has it now "normal" GPS or the mobile Version AGPS

I guess you could upgrade your radio to 1.40+ and try again. They said there's a big improvement to GPS fix.

Talking about TTFF, if you are moving, or inside a building, I think it will take longer than usual to get a fix. I live in a really urban area, but once I stand still in an open area, I usually got fix in 2-3 minutes, without exception.

Someone did a test in the Trinity forum - the accuracy of the qualcomm chip is even better than that of the sirf-iii.

However, a major problem though is the lack of a software assisted gps problem that can improve the ttff time. (Though qualcomm said there's one, but until now it's still vapourware.)

I also have the Trinity and can back up the above comments. I have a Sirf III device as well and apart from the Time To First Fix being quicker there is no noticeable difference between the two - both very accurate and don't lose their fixes.

Really interesting. The author of this article think that the Kaiser will have a Sirf-III. Now I think for the first time, we got a device with 2 GPS, a dedicated Sirf-III GPS chip together with a Qualcom integrated GPS.

I would imagine it will greatly increase the accuracy as well as the TTFF :D

Oh, wait, HTC might disable the Qualcom GPS, and just use the Sirf-III. See what they did to Hermes :D :D

Does anyone know how to start the gPS on the Kaiser - I bought one ...but don`t know how to start !
