中国区域定位系统（ Chinese Area Positioning System ， CAPS）把寿命末期的地球静止轨道（ Geostationary Earth Orbit ， GEO）通信卫星推到比GEO轨道高约200 km的倾斜高圆轨道（ inclined Highly Circular Orbit ， iHCO），卫星相对地球向西漂移。利用该类卫星组建CAPS导航星座，可以实现全球范围内的导航通信覆盖。重点开展基于iHCO通信卫星的CAPS星座优化研究，结果表明：利用GEO通信卫星和iHCO通信卫星组成的星座可以实现较好的空间星座布局，可以满足一般导航用户的需要。

The Chinese Area Positioning System ( CAPS) is a navigation system based on communication satellites.The system can provide world-wide navigation and communication services by using iHCO ( inclined Highly Circular Orbit ) communication satellites , which are previous GEO ( Geostationary Earth Orbit ) communication satellites reset to altitudes of about 200 kilometers above the GEO for new use after their planned communication services .This paper presents a study of CAPS navigation constellations of iHCO satellites.Our study yields the most optimized CAPS navigation constellation to meet the needs of ordinary navigation-service users .
