An Overview and Initial In-Orbit Status Of “Index” Satellite

Abstract

INDEX ( REIMEI ) is a small satellite with 72kg mass, and is provided with three-axis attitude controlled capabilities for aurora observation. REIMEI was launched into a nearly sun synchronous polar orbit on Aug. 23rd, 2005 (UT) from Baikonur, Kazakhstan by Dnepr rocket. REIMEI satellite functions works satisfactorily in the orbit. Three axis control is achieved with accuracy of 0.05 deg. Multi-spectrum images of aurora are taken with 8Hz rate and 2 km spatial resolution and are being analyzed to investigate the aurora physics.
