Blackberry Storm 9530 + GPS + Telus Carrier

[ Edited ]



I just downloaded the Blackberry JDE and started playing around. So far it's amazingly interesting. I now want to develop my own app, which would act as a speedometer, so I can have an idea of how fast I am skiing downhill. I figured I'd use the built-in GPS, but before I go further, I would like to know a few things.


- Is the Autonomous mode fast enough to get the moving speed or are others mode accurate enough?

- Do I need to pay extra fee to use the GPS?

Anything special to know about Telus and the GPS features? I read about GPS on verizon and vodafne, but what about Telus, is it reliable?

- Are you aware of any limitation?


Thank you!

The stand-alone mode on the Storm is independent of the carrier. Since your application is to be used outdoors, there should not be any reason to use network assist. Autonomous has your best accuracy anyway.


The "time to first fix" on your Autonomous mode is going to take 30 - 120 seconds on this device, if you have a clear view of the sky. Since you need continuous fixes, I suggest implementing the location listener interface with a frequency of about 10 seconds. This will keep the chip hot and be very accurate and fast after the first fix.


AFAIK, you don't pay any additional fees in stand-alone mode.
