Computer Program for Design and Performance Analysis of Navigation-Aid Power Systems. Program Summary.

摘要

A computer program developed for the performance analysis of a spacecraft power system is capable of performing all the calculations necessary to understand the overall characteristics of solar array-barrery power systems for application to aids to navigation. The DSPA (Design Synthesis/Performance Analysis) Computer Program will ebable the Coast Guard to design solar array/battery power systems for aids to navigation having any specific flashing lamp load and at any geographical location, simulate the performance of solar array/battery power systems in operation on navigation aids under specific flashing lamp load and environmental conditions, and provide specifications for viable alternative designs which may be used to integrate solar array/battery power systems into the Coast Guard inventory. The DSPA Computer Program was verified by comparing the predicted operational characteristics of specified power systems with the actual performance of these same power systems. The Computer Program accurately predicted the changes in battery state-of-charge over a one year period for two power systems considered successfully tested by the Coast Guard.
