Distance Calculation by Lattitude/Longitude

Hassan.. have you seen this FPU.. dedicated routines

32-bit float is also working fine on uc

Yes I know, but if they are using their own routines GPS input, arcsin...etc.. they will have overcome some of the shortfalls. It looks as if this chip was developed to do exactly what you need to do...look at the version 3

can i simulate this chip??

I don't know it looks to me like a bog standard pic you MAY be able to get the hex file... but I doubt it.

ohhh yess its working fine for short distances which i want
x = (lon2-lon1) * cos((lat1+lat2)/2);
y = (lat2-lat1);
d = sqrt(x*x + y*y) * R;
