How to convert GPS coordinates from Chinese tracker to GOOGLE MAPS coordinates?

Question

satellite navigation

There is a GSM tracker tk-102.
Configured for GPRS data transfer.
Answer I get a line:
(027042966861br00150128a4826.8754n04504.5132e020.613335984.82000000000l00000000) I
understood a little and understood where the coordinates here:
x = 4826.8754
y = 04504.5132
But the problem is that these are incorrect coordinates and they are shifted by about 8 kilometers from real. I read an article on Habré habrahabr.ru/post/175451 , there is a similar tracker and a person found that WGS-84 is used here. But when trying to convert to normal coordinates using the WGS-84 algorithms, I got the coordinates somewhere in AFRICA.

Answer 1

JS conversion formula
var X=Math.floor(N/100)+((((N/100)-Math.floor(N/100))*100)/60);
var Y=Math.floor(E/100)+((((E/100)-Math.floor(E/100))*100)/60);

Answer 2

Tell me what is the real coordinate in this line, not near Volgograd by any chance?
PS Judging by the line, I got it in the format degrees and decimal degrees N48.447923 E45.075220. If the coordinate is correct, then everything is correctly transmitted.
