Like this, sort of...


The "heading" value should be what the compass returns if available. Otherwise it's extrapolated from the moving direction.

uh-huh.

Can you open the file %Temp%\glbasic\gpc_temp0.cpp and see what line 151 is?

See the attached file.
Code (glbasic) Select


// -------------------------------------------------------
// distance between 2 GPS points in [m]
// -------------------------------------------------------
FUNCTION GPS_dist: lat1, lon1, lat2, lon2
CONSTANT R  = 6371000
CONSTANT PI = 3.14159265358979323846264338327950288

LOCAL dLat, dLon, a,c,d
dLat = (lat2 - lat1)
dLon = (lon2 - lon1)
a = SIN(dLat / 2) * SIN(dLat / 2) + COS(lat1) * COS(lat2) * SIN(dLon / 2) * SIN(dLon / 2)

c = 2.0 * ATAN(SQR(a), SQR(1.0 - a))*PI/180.0
d = R * c
RETURN d
ENDFUNCTION



This might be handy as well.
