dc.description.abstractThe ERG project will explore why relativistic electrons exist in the Van Allen belts by observing plasma/particles in wide energy range and electric/magnetic fields in wide frequency range. It will be essential for understanding the particle acceleration and loss mechanisms and the dynamical evolution of space storms. The ERG is a sun-oriented and spin-stabilized satellite with the spin rate of 7.5 revolutions per minute. The altitudes of perigee and apogee are 300 and 30000 km, respectively. The satellite consists of a payload module and a bus module. The payload module has 8 sensors: four electron sensors, two ion sensors, a magnetic an electric field sensor and a plasma wave sensor. The ERG satellite will be launched in 2016 by the Epsilon rocket at Uchinoura Space Center. This paper presents the results of the thermal vacuum test in May 2016. We confirmed the performance of the satellite in hot and cold temperature estimated in the orbit, and got the data for correlation of the thermal mathematical model. We conducted the on-orbit thermal analysis using the correlated thermal mathematical model for the final confirmation of the thermal design and for the on-orbit operation. We will present the on-orbit evaluation of the thermal design and analysis.
