The software used for planetary missions is derived from mathematics that use matrix notation.  An alternative is to use Einstein summation notation, which enables the mathematics to be presented in a compact form but makes the geometry difficult to understand.  In this book, the relationship of matrix notation to summation notation is shown.  The purpose is to enable the reader to derive the mathematics used in the software in either matrix notation or summation notation. This brief is a useful tool for advanced students and young professionals embarking on careers in planetary navigation.weiterlesen
