Downloadable Programs
- Balloon Track for Windows, A Windows
prediction program. Click the link for more details.
- BALLTRAK.ZIP, WB8ELK's prediction
software. MSDOS BASIC requires GWBASIC, QBASIC or other suitable basic
interpreter.
- FloaTrak is Bill Brown's Balltrack with a
user interface I've added. The program is an executable DOS program. It's a
bit more user friendly than Balltrack because you can create data files for
import into the program rather than having to manually key in each data point
every time you run the program. "FloaTrack", as the name indicates, has been
tinkered with to allow for zero pressure floaters.
I recommend you use
Balloon Track for Windows
if you are running a Windows 98/ME/NT/2000 or XP OS. It has many additional features
and makes running predictions quite fast and easy (once you learn its tricks).
- LIFTWIN Ver 0.41 The balloon
inflation and lift calculation program written by Hank Riley, N1LTV. This
comprehensive lift and ascent prediction program uses a what-if gridded
style data display to answer just about every question outside of track
prediction that might arise in the planning and execution of a balloon
launch using helium or hydrogen (runs on all Windows versions, with the
possible exception of Vista, from Windows 3.1 up to and including Windows 7,
32 bits).
NOTE: It is possible to run LIFTWIN in Windows 7 since it has
been verified to run under the 32 bit version. Simply place the program
in a folder and place the
VBRUN300.DLL file
in that same directory and you should have no problems. Hank Riley will
be putting up a new official LIFTWIN website shortly.

Spread Sheets of Practical Use
- convert_Height_Millibars.xls
- WARNING this spreadsheet previously had been
discovered to produce inaccurate results. I'm "beta testing" the
revised version posted here with a few
folks to ensure we all agree it's OK. So until this warning is removed be
advised of potential problems. (18K) Excel Spreadsheet, Calculate altitude from pressure, pressure from altitude
and convert pressure to pressure (eg: mbar to Torr). Spreadsheet is protected
to avoid inadvertent destruction, but there is no password so you can
unprotect and fix, enhance etc.
Various Formulae
Aviation Formulary
Ed Best maintains an excellent page of useful formulae for dealing with
latitude, longitude and lots of derived information from these points. The
formulae are for "aviation" but they work for any lat/long computational need.
