Well, the obvious thing to do is to take geodesic polar coordinates. Have you tried that? You should be able to prove that constant Gaussian curvature forces the metric to take a particular form, and this will in turn imply that geodesic circles have constant geodesic curvature. – 2011-05-11

@Zhen Lin: Why is it not possible to simply/algebraically express geodesic curvature in terms of Gaussian curvature and $u_0 $? koletennbert's question has not yet been answered. http://math.stackexchange.com/questions/162474/curvature-of-geodesic-circles-on-surface-with-constant-curvature?rq=1 – 2014-09-25

I expected to arrive at a result maybe somewhat like $ u_0 K +1/u_0.$ – 2014-09-25
