The paper presents a framework to emulate spacecraft orbits using GNSS hardware in the loop that enables the evaluation of new orbital positioning algorithms. The framework software generates the spacecraft orbit and the GNSS signals, including the most common perturbations. These signals are modulated and transmitted by a software-defined radio and received by a commercial GPS receiver. The system is validated using a test orbit, where the GPS receiver accurately determines the spacecraft positions. Moreover, using raw data provided by the receiver, the spacecraft positions have also been determined by software for a low earth orbit, in which civil GPS receivers do not work.

The way to eat and the way to serve food is one of the most explicit cultural styles. Chinese food utensils and eating furniture contain the Chinese view of nature and material use. In order to reflect Chinese cultural meaning in the design of Chinese food utensils, the iconic symbols and material design should not be left to the curiosity of formal innovation, but ignore the transmission of cultural meaning in the works, so that the existing works of Chinese meaning tableware design often present Therefore, the existing Chinese tableware design works often show unsatisfactory results. The author believes that if Chinese tableware design products are to go global, they must reflect the demands of Chinese cultural experience in terms of shape, material and combination, and meet the aesthetic needs and practical functions of contemporary design. In this paper, we take the Chinese cultural symbolic element "bamboo" as the theme, and combine wood and traditional metal hammering and forging techniques to create "ware joint", which has been exhibited in many countries. As an example, an exploration is conducted on the creation of Chinese cultural meaning in tableware design by combining wood and traditional metal hammering and forging techniques.

Utilization of IGS Information for Improved Real-time GPS Positioning

Utilization of IGS Information for Improved Real-time GPS Positioning by Francis James Barchesky The estimation of a precise user's position is a difficult and complex problem. In addition, the use of geodetic grade position instruments is often not possible for Small Unmanned Aerial Vehicle (SUAV) systems. However, the availability of the global navigation satellite system (GNSS) and International GNSS Service (IGS) predicted product data allows an attempt to increase the precision of a navigation algorithm, which is the aim in this thesis. The utilization of this information within an algorithm work environment is a complex problem, requiring the development of multiple tools in order to use and access the IGS raw and product data. Therefore, the overall goal of this research project was the development of these tools using MATLAB®. The IGS information provided by these tools allows access to a particular set of product and raw data files. The available predicted product data is used to increase the precision of the position estimate for a real-time application. Within this, the conversion from a long time interval to a fast update rate was determined. The use of this information requires these tools to also include important orbit determinations of the GPS satellites. The use of only precise satellite position information from the developed M ATLAB tools is evaluated by a comparison of a position estimation algorithm using recorded satellite position information and the developed satellite position information from the IGS predicted data. The results show an increase in performance of position estimation with the use of the created MATLAB tools. A discussion in how the use of the created tools could further be expanded to increase the accuracy and precision of a position estimation algorithm is presented. iii Acknowledgements I would like to thank Dr. Marcello Napolitano, my research advisor, for your support, guidance and teachings throughout my education.
