【摘要】 通过对静地同步卫星(GEO)、倾斜轨道同步卫星(IGSO)/GEO结合和MEO/GEO结合等星座的精度因子(DOP)计算和分析,初步探索了利用混合星座解决无高程辅助的纯GEO星座不能垂向定位和水平定位精度欠佳的问题。同时,结合我国卫星导航系统的发展,提出利用IGSO/GEO混合星座作为区域定位星座向全球定位星座过渡的观点。更多还原

【Abstract】 According to the calculation and the analysis of dilution of precision (DOP) of GEO, IGSO/GEO and MEO/GEO constellation, a composite satellite constellation solution, to solve the incapable positioning in vertical direction and low positioning precision in level surface without assistant altimeter with pure GEO constellation, is investigated. In the meantime, combined with our nation’s navigation system, a viewpoint on using IGSO/GEO composite satellite constellation as a transition from regional positioning constellation to global positioning constellation is put forward.更多还原
