Spacecraft Telemetry Monitoring Method Based on Dimensionality Reduction and Clustering

Autor: Yoshinobu Kawahara, Takehisa Yairi, Minoru Inui, Noboru Takata

Publikováno v: JOURNAL OF THE JAPAN SOCIETY FOR AERONAUTICAL AND SPACE SCIENCES. 59:197-205

Development of intelligent system monitoring and fault detection techniques for spacecraft is of a great interest in the space engineering. In this paper, we propose a “data-driven” anomaly detection framework for spacecraft telemetry data using

A novel concept of satellite design, named “PETSAT,” is proposed and its system design and control aspect is discussed in this paper. In this concept, a satellite is made of several “Functional Panels” such as “Communication panel,” “At

Identification of Causal Variables for Building Energy Fault Detection by Semi-supervised LDA and Decision Boundary Analysis

Autor: M. Shioya, Minoru Inui, Y. Masukawa, Takehisa Yairi, K. Yoshida, K. Machida

Publikováno v: ICDM Workshops

This paper addresses the identification problem of causal variables for the system anomaly. In real-world complicated systems, even experts often fail to specify causal factors, thus they attempt to detect the anomaly with exploratory heuristics. Our

Adaptive Limit Checking for Spacecraft Telemetry Data Using Kernel Principal Component Analysis

Autor: Takehisa Yairi, Yoshinobu Kawahara, Minoru Inui, Kohei Goto, K. Machida

Publikováno v: TRANSACTIONS OF THE JAPAN SOCIETY FOR AERONAUTICAL AND SPACE SCIENCES, SPACE TECHNOLOGY JAPAN. 7:Pf_11-Pf_16

In space development, early anomaly detections of the space systems, especially detecting symptom of anomaly, and early measures against them are very important. In this study, we introduce a model acquisition method for spacecraft telemetry data usi
