Subject: [Nml] Calculators for navigation

Hi,
I wrote a number of Excel spreadsheets for celestial navigation in
the past (NAVTAB) and published them on my web site. People
said they worked quite well but others complained they couldn't
use them because they didn't have Excel (probably due to high
price). Presently I am playing around with JavaScript which seems
to be very useful for writing small programs for technical and
scientific applications. Interactive HTML forms containing
JavaScript code provide the full functionality of a spreadsheet with
the exception that they do not store data after leaving the program
(which is tolerable). JavaScript programs are very compact (a
couple of kB only) and require only a web browser (e.g.; Netscape
Navigator).
Sight Reduction Calculator 1.04 can be tested at:
