Embodiment Construction
[0024] The present invention is further described below with reference to the accompanying drawings and an example during a manned space flight mission.
[0025] At present, in the fields of aerospace measurement and control, communication and navigation, and related technologies, it involves using the thermospheric atmospheric density model to calculate the atmospheric density when determining the orbit of the spacecraft. In manned spaceflight missions, the thermospheric atmospheric density models used include three types: Jacchia series, MSIS series, and DTM. like Figure 4 As shown, the method of the present invention is used to correct the density of the thermosphere atmosphere as follows:
[0026] Step 1. Select the model for calculating the atmospheric density of the thermosphere
[0027] The orbit calculation accuracy of each thermosphere atmosphere density model is calculated, and the thermosphere atmosphere density model with the highest orbit calculation accuracy i...
