Hardware and software control for the NASA EOS satellite power system testbed

Abstract

For the implementation of the NASA EOS testbed programmable operations, a control/data acquisition system has been designed, implemented, and tested. The work is focused mainly on the hardware design/build of the custom interface board and software development for real-time control and data acquisition of the testbed. Also, an application program was designed to control, collect, and display the data and parameters of the testbed elements, and troubleshoot the hardware. An algorithm was chosen and applied to the battery simulator control after computer simulations. The final experiment results were obtained successfully, which proved the design to be correct, as the testbed could be operated under computer control.
