Abstract:

The Error Model Best Estimate of Trajectory EMBET is derived for a tracking system measuring any linear combination of ranges and range rates. Provisions are made for the introduction of any functional statistical constraints on the coefficients of the error model. Provisions are also made for the introduction of dynamic constraints expressed either in terms of explicit functions or in terms of general differential equations of motion. A rigorous extension of EMBET to apply to a hierarchy of orbits rather than individual trajectory points is developed. It provides an altogether practical solution to the long standing problem of the simultaneous adjustment of all observations made by all sensors on an unlimited number of orbits or epochal intervals. This extension, called NEO-EMBET N-Epoch Orbital EMBET, also calibrates both stable and unstable components of the error models of all observational channels while simultaneously estimating the orbital parameters at all specified epochs as well as any gravitational and drag parameters considered to be unknown.
