초록

A method of determining an orbit of an orbital object includes computing predicted tracking measurement values based on the orbit computed from the initial conditions factoring in any modeled environmental forces and realistic maneuvers; computing the differences between the actual and predicted tracking measurements; determining an improved estimate of the initial conditions that reduces the measurement errors using a minimization or root finding algorithm; after the algorithm has converged, reviewing the hypothetical maneuvers in the force model, takin...

1. A method of determining an orbit of an orbital object, comprising: (a) specifying a set of tracking measurement values for the orbit using at least one processor;(b) specifying a force model to represent forces acting on the orbital object;(c) selecting a numerical or analytical integration scheme to compute the object's orbit;(d) specifying known initial conditions including position and velocity for the object;(e) distributing a series of maneuvers over the potential range for which maneuver solutions may occur;(f) applying an orbit propagation sche...
