摘　　要：根据火灾监视对卫星载荷和卫星轨道的约束,基于低轨太阳同步回归轨道讨论了火灾监视卫星星座的设计,由卫星对地覆盖几何关系求解了典型卫星星座的星载传感器参数。计算结果表明:设计的火灾监视卫星有较高的地面分辨率,火灾监视卫星星座的最大轨道响应时间6h,平均响应时间3h。The design of the fire monitoring constellation based on the low sun synchronous orbit was discussed according to the payload and orbit constraints in fire monitoring in this paper. The payload parameters of classic constellation were solved according to the satellite coverage geometry. The results showed that the constellation designed would provide high resolution, which maximum and mean response time were 6 hours and 3 hours respectively.
