ASEN 5070: Statistical Orbit Determination I Fall 2013 Marco Balducci Professor Brandon A. Jones Professor George H. Born Lecture 17: Exam 1 Review
Office Hours • Instead of Thursday office hours, I’ll have office hours between 12 and 5 on Wednesday
Outlines of Topics to Date • Flat Earth Problem • Linearization Procedure • State Transition Matrix • A(t), H(t), etc. • Least Squares (weighted and w/ and w/o a priori) • Minimum Norm • Probability and Statistics • Statistical Least Squares
Review • What is n ? • Dimensions in the state vector • What is l ? • Number of observations • What is p ? • Dimensions in the observation vector • What is m ? • Number of equations m = p x l

Review • What is n ? • Dimensions in the state vector • What is l ? • Number of observations • What is p ? • Dimensions in the observation vector • What is m ? • Number of equations m = p x l
Review • The state has n parameters • n unknowns at any given time. • There are l observations of any given type. • There are p types of observations (range, range-rate, angles, etc) • We have p x l = mtotal equations. • Three situations: • n < m: Least Squares • n = m: Deterministic • n > m: Minimum Norm
Review • Basic Nomenclature
Best Estimate Solvers • Least Squares • Weighted Least Squares • Least Squares with a priori • Minimum Norm
Review • Two Quick Questions
Review • Application of Minimum Norm
Review • Batch Processor Overview
