Margins of Error

  • An anomaly of just 0.01 m/s in the muzzle velocity will cause the rendezvous location to shift by 44 meters. This is considered to be on the borderline of acceptability.
  • A 0.1 degree right/left misalignment in the mass-driver would only add roughly 2.5 m/s to the rendezvous velocity.
  • Variations in the timing would have very little impact on the rendezvous location, roughly approximating a parabolic free-fall trajectory of 1/2 a t², where a is the lower 1/6th lunar gravity.
  • Variations up/down in the angle which the mass-driver acts at are very easily minimized (by a simple level), and will have a very small effect on the rendezvous location by a similar argument to the timing — the orbit is nearly circular and the altitude changes very little with respect to angle around apogee.
