    HI,

    Optimal in what sense?
    Most often one's target is to have as low DOP as possible, and that is achieved by selecting a combination of satellites with the best range accuracy and the constellation geometry... take a look at wikipedia
    en.wikipedia.org/wiki/Dilution_of_precision_(GPS)
    and navpedia
    navipedia.net/index.php/Positioning_Error

    Cheers,
    Michele
