Kanazawa-SAT3: micro-satellite mission for monitoring x-ray transients coincide with gravitational wave events

We are developing a micro satellite, Kanazawa-SAT3 , to be launched in FY2019. The main purpose of the mission is to localize X-ray transients coincide with gravitational wave events, e.g. short gamma-ray bursts, and to investigate the formation of extreme space-time of black holes and the origin of relativistic jet. We are developing a wide field X-ray imaging detector as a mission instrument. It has a couple of 1-dimensional imaging systems with a random coded aperture mask and silicon strip detectors. In this paper, we introduce the mission overview and the current status of Kanazawa-SAT3 and the flight model performance.
