Abstract:

This document describes, from a programmers view, the coding function, and logic of the Spiral Decay computer program. The Spiral Decoy program operates in the SPACETRACK B-3 Semi-Automatic Programming System and will accept sensor observations, assign weights and biases to the data, perform a differential correction and predict past or future position and velocity. Section 2 of this document contains a functional description and basic flow charts of the program. Section 3 defines symbolic names, data and tape formats, and memory assignments. A detailed description of each subroutine used by Spiral Decay is given in Section 4. The Appendix describes the Adams-Bashforth integration routine which is used by Spiral Decay for ephemeris integration.
