    Re: Double altitude method
    From: Paul Bedel

    Hi Jacques,

    Here are my studies about double chronometer methods (in Great Britain).

    I did not studied Pezenas or Borda's methods for double altitude. Maybe later ! My point of interest is the study of navigation tables published between 1870 and 2000 to solve Sumner's line problem.

    Regards. 

    Paul.
