Frsky error gps position

Post by codicefiscale » Sat Jan 20, 2018 2:51 pm

Hello,
I have a gps v2 sensor, xjt module and x8r receiver. To read the gps position, I use the Frsky Dashboard.
My problem is the result: everywhere I am, I receive a position far from me about 25 miles, 40 km.
For example I am in this place (Italy)
Lat 42.3369448
Long 13.456024399999933
And on the contrary the Frsky dashboard write:
Lat 4219.8888
Long 1324.1747
Do you now it is possible to change something into the parameters?
I don't find nothing!

The value "4219.8888" is 42 degrees 19.8888 minutes, similar for "1324.1747" is 13 degrees 24.1747 minutes (60 minutes in a degree of course).
So, 4219.8888 is 42.33148, and 1324.1747 is 13.40291.

How do you calculate theese?
What is the method?
I want use this system to find the model if I loose it.
In the web I find only the degree values. What kind of measures is that used by frsky?

Look at "4219.8888", the 42 is the degrees, so just remove that giving 19.8888 minutes. Divide the 19.8888 by 60 to get 0.33148.
So the result is 42.33148 degrees.

Thank you, I notice it is the right position I was when I made the photo.
I didn't understand because with World Geodetic System 84 (WGS 84), the result in degree is different. See the photo.
Anyway, I use your method that is ok.
Thank you too
