Q2. What's the minutes and seconds of coordinate data?

A. The raw gps information from the serial is in the form: DDmm.mmmmm. e.g.If the raw

information is: 5320.12345, then it is: 53 degress and 20.12345 minutes. In order to convert

it to decimal coordinates you divide the minutes by 60. i.e. 20.12345 / 60 = .33539 Finally,

the decimal result: 53.33539 Forum reading, attached source code that prints google maps

friendly coordinates. (http://www.dfrobot.com/forum/viewtopic.php?
