This paper describes the research and development results of the precision horizon-crossing indicator for synchronous orbit (PHIS) suitable for the attitude control of a three-axis stabilized satellite operating at transfer and geosynchronous altitude. The bread-board model (BBM) for Engineering Test Satellite-VI(ETS-VI) to be launched in Summer 1992 by NASDA JAPAN was designed, fabricated and evaluated. The evaluation test results of PHIS/BBM show the excellent earth-pointing performance with respect to its on-orbit operation. And also the environmental and reliability tests have been successfully done for the sensor critical component parts. It is believed that this earth sensor will be one of the most relible and high-accuracy instrument after the 1990's.
