Space technology plays a pivotal role in society development. It offers new methods for telemetry, monitoring and control. However, this sector requires training, research and skills development but the lack of instruments, materials and budgets affects the ambiguity to understand satellite technology. The objective of this paper is to describe a demonstration prototype of a smart phone device for space operations study. Therefore, the first task was carried out to give a demonstration for spatial imagery and attitude determination missions through a wireless communication. The smart phone’s Bluetooth was used to achieve this goal inclusive of a new method to enable real time transmission. In addition, an algorithm around a quaternion based Kalman filter was included in order to detect the reliability of the prototype's orientation. The second task was carried out to provide a demonstration for the attitude control mission using the smart phone’s orientation sensor, including a new method for an autonomous guided mode. As a result, the acquisition platform showed real time measurement with good accuracy for orientation detection and image transmission. In addition, the prototype kept the balance during the demonstration based on the attitude control method. 相似文献

The space industry in established space-faring nations is playing an increasingly important role in the development of capacity in emerging space nations. The role of industry ranges from provision of turn-key systems, to provision of training and joint development of satellites in partnership with emerging space countries. Ranked number 1 worldwide in terms of satellites ordered in 2006, Thales Alenia Space is at the heart of the most high performance satellite technologies in both civil and defense sectors. The company has been involved in parterships with a number of emerging space nations. This paper discusses several key factors for successful interaction of industry with national space programmes in emerging space nations. 相似文献
