Collision avoidance manoeuvre merge[edit]

I merged the Collision avoidance manoeuvre article into this one. If anyone disagrees please discuss why here. Aalox (talk) 11:54, 7 April 2010 (UTC)

Please describe the mathematics of COLA[edit]

COLA requires application of interesting mathematics. The covariance matrix associated with a satellite's orbit state is used to construct a three-dimensional error ellipsoid. The extent to which their ellipsoids intersect or overlap gives a conceptual indication of the probability that two orbiting objects will collide (but that's not the whole story -- even if a large ellipsoid completely envelops a smaller one, there's not necessarily a 100% probability of collision). The article really needs to delve into this stuff! (talk) 14:05, 27 August 2013 (UTC)
