- Abstract:
- The problem of attitude determination (AD) has always been a challenging issue for space missions that is of importance either independently or for attitude control purposes. The problem of AD is generally focused from two aspects: measurement mechanisms (sensoring) and determination algorithms. From the former point of view, there exists a variety of measuring systems such as the Sun sensors, magnetometers, gyroscopes, star and horizon sensors that have been separately or collaboratively utilized for AD. Integrative usage of sensors not only can bring about added advantages in terms of accuracy, but also provides for estimates of attitude during special times such as the Sun eclipse. The main objective of this proposal is to prove the feasibility of a novel idea in the realm of AD sensors, and that is utility of temperature data for attitude establishment of a body subjected to thermal radiation. Since the main sources of satellite surface heating are due radiation waves emanating from the Sun and also the Erath reflections, this study focuses on experimental verification of this novel idea. Further, temperature sensors are relatively inexpensive and have a very low energy consumption rate. In this sense, the introduced experimental process of AD using temperature data is an important step forward toward verification of the proposed idea that the paves the way for its future utility in space systems
