Arduinoを用いたマイコン制御の入門教育

The programming language used in information processing education from 2011 in mechanical engineering department was changed to C from Fortran. Not only the numerical computation but also the study of the control using the microcomputer was thereby enabled and a new subject has been initiated in 2013. The name of this 4th grader's subject is "microcomputer control" and is compulsory in half year. Each individual student is using Arduino purchased by oneself, is taking the lesson and doing a programming training. The aim of this subject is to have a student understand next. (1) what is made with a microcomputer ? (2) what kind of program is necessary for it ? Inexpensive sensors and equipment were being used, were prepared subject to feel that there is interest to students. In this report, the contents of the lecture are reported including the later application around an item to treat by a lecture

A Study on Attitude Estimation for Small Satellite by Lunar Outline Extraction

In this paper, an attitude angle detection system for a small satellite at eclipse is constructed. Recently, a small satellite mission is applied to various fields, and a small satellite mission at eclipse is planned. Then it is necessary that such a small satellite keeps controlling the attitude for eclipse. In this paper, the authors propose a moon outline extraction method to detect the attitude angle for eclipse instead of equipping a star tracker and a sun sensor. The moon outline extraction captured from the satellite is used to detect the solar direction, and then the attitude angle is detected by analyzing the solar direction. Moreover to verify the effectiveness of the proposed method in this paper, substitution experiment on ground is executed, and the result is estimated
