Hi Sats Observation folks:

    I am curious why do we need to specify elevation in addition  to
longitude and latitude. Does this affect the precise apparent
positioning fixing of satellite?What is the error involved comparing say
Sea-level vs someone high up in Colorado..

    Does not seems to affect my observations of sats...

thanks  & rgds
