Abstract

TSUBAME is a micro-satellite that the students of Tokyo Institute of Technology took the lead to develop for measuring hard X-ray polarization of Gamma-Ray Bursts(GRBs) in order to reveal the nature of the central engine of GRBs. TSUBAME has two instruments: Wide-field Burst Monitor (WBM) and Hard X-ray Compton Polarimeter (HXCP). We aim to start observing with HXCP in 15 seconds by pointing the spacecraft using Control Moment Gyro. In August 2014, we assembled TSUBAME and performed an integration test during ~2 weeks.TSUBAME by communication tests with Cute-1.7+APDII in orbit. On Nov 6 2014, TSUBAME was launched from Russia and it was put into Sun-synchronous orbit at 500 km above the ground. However, serious trouble occurred to the ham radio equipment. Therefore we could not start up the X-ray sensors until Feb 10 2015. In this paper, we report the system of TSUBAME and the progress after the launch., Comment: 5 pages, 9 figures, 1 tables, 2014 Fermi Symposium proceedings - eConf C14102.1

Abstract

A 50 kg-class micro satellite “TSUBAME” was launched in 2014. After a critical phase, the receiving sensitivity of the RF system on board the satellite dropped significantly and the way for command uplink was lost. A thorough investigation was conducted after the failure to determine the causes, based on the obtained telemetry and reproductive experiments in lab room. The detailed data analysis revealed many other malfunctions had occurred. In parallel with the investigation of the fault points, we also classified these malfunctions into several categories in terms of development phase, technological aspects, and management.
