Calculate the bearing angle of any line connecting consecutive points of a traverse framework.
Known values: Bearing angle G01 and Deflection angles β1, β2, β3, β4,...., βη-2, βη-1
Result: Bearing angle G(n-1)-n
Considering that the requested angle should get a value between 0 grad and 400 grad, integral circumference multiples are abstracted:
where K integer so that the numeric expression preceding K*400 decreases as many times so the Bearing angle numeric result stands between 0 and 400 grads.
