    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.
