2024-07-11 06:27:25 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
