Help to setup GPS connection.

Hey Mbox,

I think you are close, but your degrees calculation is a little off (if I am right about you converting minutes and seconds to degrees). I know a short cut, if you can live without decimal seconds.

Say you want to convert 11 deg 14 min and 53.77 seconds to degrees. If you can live without decimal seconds, we have 11 deg 14 min and 54 seconds. To convert to degrees.degrees:

to convert minutes to degrees

(14 * 500)/3 = 2333 (really .2333 degrees)

and now convert seconds

(54 * 50)/18 = 150 (really .015 degrees)

2333
+150
=2483

or 11.2483 degrees. This result fares well with http://www.satsig.net/degrees-minute...calculator.htm , which says the result should be 11.24827 using the seconds decimals.

So with two variables you could store the result. lon_hi would = 11 and lon_low would = 2483. If you need to turn this out the serial port, your code can also place the decimal point between them.

Hi everyone, thanks for the inputs appreciated it very much...I will make tests and see the results regarding the calculation part. So far I made 30 queries by sms from the device and works okay without yet the format and calculation I desire in the mcu, right now the calculation are done and formatting within the mobile codings. I'll be away for 3 days, hopefully by end of the week I can smoothen it more.

Technos: PBP 2.50 and Python for the mobile app.
