    Hi, i have obtained a set of data from simulation from GISM software...

    however, i do not know how to calculate DOP and UERE based on the summary the data given me..the simulation provided me something like this..


    PRN
    UT
    LT
    azimuth
    elevation
    sat.lat
    sat.long
    S4
    sigma_phi
    Angular deviation
    Coh. length
    PLL
    DLL
    C / N
    Proba of LoL
    Range error
    Faraday rotation
    pseudo range
    Doppler(Hz)
    Distance error
    Angular error


    1) DOP can be obtained from standard deviation of position of satellite right? but anyone tell me how to get altitude to obtain its ECEF position? =)

    2) Is Range Error (typically > 4 and < 15) the UERE ?

    Hope that there's someone here who can help me to solve my puzzled mind... thanks!
