| Abstract: | The elevation of satellite is one of the main factors in order to get the high precision results by users.This paper introduces the powerful function of TEQC software and the plot function of QCVIEW32 and TEQCPLOT.The methods of calculating satellite's elevation with broadcast ephemeris and precise ephemeris are described in detail.The examples of application were presented.Some research is made to analyze the error feature of elevation.The result indicates that the precision of elevation got from the broadcast ephemeris by TEQC can meet the common users' need. |
