Abstract This article introduces the principle of Extenttech evaluation method and application to occultation locationing and inversion.The experiment proved that the different elevation angles and geometric distribution have influence on occultation satellite positioning and the accuracy of inversion. Compared with the conventional method,it shows that the occultation positionnning accuracy and stability of the inversion with this method has been significantly improved.
Key words ：
GPS
occulation technology
