Other AbstractThermosphere density model plays an important role in low Earth satellites orbit determination and forecasting. There are two ways to input geomagnetic and solar radiation parameters when using thermosphere models, namely, fixed parameters input and variable parameters input. Using MSIS90 model and Tiangong-1 orbit data, the precision of orbit determination and forecasting is analyzed with different input methods of parameters, different length of data and different geomagnetic parameters. Results show that the method of fixed parameters input is better with less observation data in geomagnetic quiet condition. However, in long-term orbit forecasting with more observation data, the method of variable parameters input is more accurate and easier to operate.
