摘要
面向区域的地球同步轨道(GEO)红外预警卫星能为特定区域反导作战提供及时可靠的预警信息,想定了预警区域的经纬度范围,提出以空域覆盖性能和定位精度为性能准则部署GEO预警卫星。首先基于GEO卫星对地覆盖模型建立了卫星空域覆盖性能模型;然后分析GEO卫星与特定预警区域的空间几何关系,以几何精度衰减因子(GDOP)为定位精度衡量指标,建立了GEO星座对预警区域的定位精度模型;最后通过仿真综合分析了不同卫星部署方式对空域覆盖性能和定位精度的影响,给出了面向区域的GEO红外预警卫星部署的指导性结论。
Abstract
Area-oriented geosynchronous orbit (GEO) IR early-warning satellite can provide reliable early-warning information in time for anti-missile operation in specified area.With the scenario of longitude and latitude ranges of early-warning area,it was proposed to deploy GEO early-warning satellite by using airspace coverage performance and positioning accuracy as the performance criterion.Firstly,a satellite airspace coverage performance model was established based on GEO satellite-to-ground coverage model,space geometry relation of GEO satellite with the specified early-warning area was then analyzed.By using geometric dilution of precision (GDOP) as the positioning accuracy measurement index,a positioning accuracy model of GEO satellite to the early-warning area was established.Finally,a comprehensive analysis is made by simulation of how different ways of satellite deployment affect the airspace coverage performance and positioning accuracy,drawing a guidance conclusion for area-oriented GEO IR early-warning satellite deployment.
