Abstract:

This report documents the results of an independent stability and control analysis of the control systems and procedures of the navigation development satellite NDS for the global positioning system GPS. The analysis consisted of detailed analytical investigation substantiated with sophisticated satellite system modeling and simulation of the following GPS mission events Spin phase, Despin, Earth acquisition, Panel deployment, Sun acquisition, and On-orbit operations. The results of the analysis indicated satisfactory performance in all mission phases analyzed. A redesign of the jet control system was recommended to facilitate earth acquisition operations. Author
