| Abstract: | The development status of low-orbit satellite projects and the retrieval procedure of temperature and pressure are introduced.The retrieval temperature values of CHAMP occultation data in different upper boundary height are discussed and analyzed.The results show that the bigger the upper boundary height is,the higher the retrieval accuracy of temperature; the smaller the upper boundary height is,the bigger the influence of model errors on the retrieval accuracy of temperature and pressure is. |

| Keywords: | GPS occultation retrieval temperature pressure |
