Destination point given distance and bearing from start point

Given a start point, initial bearing, and distance, this will calculate the destination point and final bearing travelling along a (shortest distance) great circle arc.

Formula: lat2 = asin(sin(lat1)*cos(d/R) + cos(lat1)*sin(d/R)*cos(θ))
  lon2 = lon1 + atan2(sin(θ)*sin(d/R)*cos(lat1), cos(d/R)−sin(lat1)*sin(lat2))
  d/R is the angular distance (in radians), where d is the distance travelled and R is the earth’s radius
var lat2 = Math.asin( Math.sin(lat1)*Math.cos(d/R) + 
                      Math.cos(lat1)*Math.sin(d/R)*Math.cos(brng) );
var lon2 = lon1 + Math.atan2(Math.sin(brng)*Math.sin(d/R)*Math.cos(lat1), 
Excel: lat2: =ASIN(SIN(lat1)*COS(d/R) + COS(lat1)*SIN(d/R)*COS(brng))
lon2: =lon1 + ATAN2(COS(d/R)-SIN(lat1)*SIN(lat2), SIN(brng)*SIN(d/R)*COS(lat1))

For final bearing, simply take the initial bearing from the end point to the start point and reverse it (using θ = (θ+180) % 360).


$IIXDR,U,12.8,V,VAH30*04 (Voltage)
$IIXDR,G,0299,,VAH30*57 (Remaining Amp Hours)
$IIXDR,I,-002,A,VAH30*05 (Current)
U = Voltage
G = Remaining Amps hours
I = Current
A = Angle? (description field used as HDC, PIT, ROL (heading, pitch, roll) in nexus)
So it seems there is one letter for each meaning
