   Thanks go to Professor T.S. Kelso at the US Air Force Institute of
Technology, on whose documentation and FORTRAN implementation of the various
NORAD orbit models much of the orbit side of this application is based. Without 
this information, this application would have been a lot longer in coming, and 
the quality of the predictions may also have suffered.

   This application was written using the Acorn C Compiler, version 3.2b, but
without any use of the standard RISC_OSLib modules, which unfortunately do not
live up to the high standard of the compiler. Instead, I used the excellent
DeskLib, which made this, my first large RISCOS project, that much easier.
Thanks are then due to the many authors of DeskLib: Jason Williams (DeskLib
moderator), Edouard Poor, Philip Banks, Tony Bryant, David Pilling, Keith
Marlow & John Winters.

   Thanks also go to the users of earlier versions of this application, in 
particular Carl Cepurneek & Mike Tullet, whose feedback and suggestions have
been very helpful. Just because some suggestions have not been included in this
release does not mean that I have forgotten about them, but merely that I
haven't had time to implement them yet !!

   Final thanks go to the people on Usenet groups comp.sys.acorn, and
comp.sys.acorn.tech, many of whom have taken the time to answer my frequent 
queries to these groups, that have enabled me to write this application. Keep 
up the good work !!
