Geosynchronous orbit satellite is usually the first early warning equipment to catch ballistic missile launches in actual combat. However, the detection information it provides is lack of dimension, which makes the traditional target guidance method hard to be directly applied on the target guidance for low-orbit satellite. Aiming at this point, this paper studies the target guidance method for low-orbit satellite by geosynchronous orbit satellite. First, based on the altitude constraint of infrared radiation during the launch and active flight of the ballistic missile, the azimuth and pitch detection ranges of the infrared sensor of the low-orbit satellite are calculated with the guidance of one geosynchronous orbit satellite. Then, the detection distance of the infrared sensor of the low-orbit satellite is modeled and calculated, which leads to a successful target detection for the low-orbit satellite. Finally, the effectiveness and accuracy of this method are verified through a numerical simulation experiment.
