Geophysical Constant Determination from Satellite Observations: Digital Computer Program

摘要

The computer program is based on a development of the Minimum Variance Method contained in Report AFCRL-65-579 (Martin Marietta Report ER 13950, Ref. 1). The partial derivatives of the rectangular coordinates with respect to the classical elements, which are not covered in Ref. 1, are given in the appendix. A general description of the program including discussion of the inputs, operating modes, initial value estimation and a test sample is presented. Also included are the program inputs and outputs, lists of symbols, flow charts and other essentials necessary to operate the program and to facilitate any subsequent modifications. The program is written in FORTRAN IV and machine language (MAP). The major part of the program is in double precision. (Author)
