I have taken SatTrack-3.1.7, fixed the year 2000 bug in it,|
altered the Makefile for OS X and updated gettle (get two line elements).
Update: July 2003
gettle updated by KL7NA, Rob, to use curl since
the ftp download site has been closed. Thanks Rob!
Before you go through all of this, you might want to consider
using MacDopplerPRO from
Dog Park Software
It is less than 6 MB and displays more information than sattrack.
On the other hand, sattrack is open source (free) and MacDopplerPRO requires
that you register, although it does appear to work to some degree for free.
If you want to compile the sattrack source code
you will need to install the Developer CD. This is available
from Apple free.
I am including a compiled binary so this should not be required
just to run it. If you have problems with the binary please
To run SatTrack with the graphical display
you will also need to download and install X11 display software.
I recommend the free package from apple, based on XFree86 4.2.1.
NOTE: this constitutes about 42 megabytes
Finally we come to SatTrack itself.
If you are using Safari, Control-click on the link.
Otherwise click and hold on the link until a pull down menu
appears, select Save Link As

You should put this file in your Home directory. SatTrack
expects to be in a Home directory, if you put it elsewhere,
you will have to modify things in the installation and
configuration on your own.
(If your browser automatically downloaded it and unpacked
it somewhere like on your desktop, drag the whole folder to your
In a Terminal window, type the following shell commands:
tar xf sattrack_osx.tar
Assuming the tar succeeded you can now
If you want to compile it yourself now you can type
SETTING YOUR PATH
If all goes well, you should now have sattrack
and its utilities. To use it conveniently you should
put its directory in your path in your .login file.
Mine looks something like this:
set path=(. ~/bin /usr/local/bin /bin /usr/bin /sbin /usr/sbin ~/SatTrack/run
so your shell will accept the new path.
At last, you should be able to start X11 and sattrack.
Double-click the X11 icon in your applications folder.
(I put X11 in my dock for convenience)
When it is ready, an xterm window will open.
Put your cursor inside it and type
Please refer to the SatTrack documentation ~/SatTrack/doc/sattrack.doc
(a plain text file) for the details of operating sattrack.
You might want to put the following file in your home directory
to automatically open an xterm appropriately sized for sattrack
when starting X11.
# merge in defaults and keymaps
if [ -f $sysresources ]; then
xrdb -merge $sysresources
if [ -f $sysmodmap ]; then
if [ -f $userresources ]; then
xrdb -merge $userresources
if [ -f $usermodmap ]; then
# start some nice programs
xclock -update 1 -geometry 100x100-1+1 &
