In order to observe celestial X-ray sources, we are going to develop a large area proportional counter as a payload of space vehicles such as sounding rocket, balloon and scientific satellite. In this study, we reviewed the proporties of X-ray sources and cosmic background, and we studied the conceptual design for a large area proportional counter.
