Method and system for evaluating stare-time by a pointing system

摘要

A method and system to evaluate stare-time of a selected target by a pointing system is provided. In an embodiment, the method includes specifying a time period for evaluation. A processor simulates movement of selected celestial bodies during the time period and movement of the platform during the time period. The processor further simulates pointing the pointing system in each celestial direction during the time period. The method calculates stare-time in each celestial direction uninterrupted by the selected celestial bodies and the platform during the time period.

1. A method for evaluating performance of a pointing system mounted on a platform comprising:
specifying a time period for evaluation; simulating movement of selected celestial bodies during the time period with a processor; simulating movement of the platform on a non-orbiting path during the time period with the processor; simulating pointing the pointing system in each celestial direction during the time period with the processor; calculating stare-time in each celestial direction uninterrupted by the selected celestial bodies and the platform during the time period with the processor; and controlling pointing of the pointing system with a control device based on the stare-time calculated with the processor.
