    Hi Ted
    
    I capture both of what I believe to be the Elisa s/c based on your and 
    Kevin's work, 99901 being the first seen and 99902 the second:
    
    99901 99 901A   8049 G 20120710062112966 15 25 1653692+390197 37 S
    99902 99 902A   8049 G 20120710062112966 15 25 1651880+385926 37 S
    
    Time may be abit out +/- 0.1 seconds as GPS was not locked.
    
    Regards,
    Scott Tilley
