Latitude Longitude in wrong format DDDMM.MMMM 2832.3396N

Question

I have a gps module that gives me latitude in longitude in a weird format.

DDDMM.MMMM

As written on user manual, Degrees*100 + Minutes.

As far as I know, It is degrees minutes seconds, and seconds is between 0-59, above than this will increment the minute. But this is giving minutes in decimal places. Does this means 1/1000th of a minute?

eg. 07717.3644 E
077 --> degrees
17 --> minutes
3644 --> ?
E --> Direction

Also how will I convert it to decimal, I am using the formula

decimal = degrees + minutes/60 + seconds/3600.

Answer 1

To convert this to the decimal format, we start by keeping the DD portion and simply divide the MM.MMM by 60 to firm the MMM portion of the decimal format.

43. (48.225/60), -79.(59.074/60)  

43.(0.80375), -79.(0.98456)  

43.80375, -79.98456    

In your case

eg. 07717.3644 E is the DDDMM.MMMM format

077 --> degrees
17 --> minutes
.3644 --> minutes equals to sec/60


decimal = degrees + minutes/60 

decimal = 77 + (17.3644 / 60)  

decimal = 77.28941

Follow the algorithm to convert the same.

var t = "7523.7983" // (DDMM.MMMM)
var g = "03412.9873" //(DDDMM.MMMM)

function lat(t){
  return (Number(t.slice(0,2)) + (Number(t.slice(2,9))/60))
}

function lng(g) {
  return (Number(g.slice(0,3)) + (Number(g.slice(3,10))/60))
}

console.log(lat(t)) 
console.log(lng(g))
