This is a reformulation of the geodesic problem. The notation is as follows:
- at a general point (no suffix or 1 or 2 as suffix)
- phi = latitude
- beta = latitude on auxiliary sphere
- omega = longitude on auxiliary sphere
- lambda = longitude
- alpha = azimuth of great circle
- sigma = arc length along great circle
- s = distance
- tau = scaled distance (= sigma at multiples of pi/2)
- at northwards equator crossing
- beta = phi = 0
- omega = lambda = 0
- alpha = alpha0
- sigma = s = 0
- a 12 suffix means a difference, e.g., s12 = s2 - s1.
- s and c prefixes mean sin and cos
