Orbital Mechanics with Numerit Pro
Welcome
This web site contains Numerit Pro applications that
can be used to solve a variety of technical problems in orbital mechanics. This suite of programs can be used for
practical aerospace mission analysis in the areas of orbit design, visibility
and shadow prediction, lunar and interplanetary trajectory analysis, and
orbital transfer.
Numerit Pro is an integrated
problem-solving environment (IPSE) for Windows that is inexpensive (only $99),
yet powerful and easy to use. This
software environment includes a program editor, equation editor, report writer,
debugging features and interactive graphics.
The Numerit Pro programming language is a high level
structured language similar to Fortran, BASIC and MATLAB. Additional information about Numerit
Pro, including an evaluation version for download, and the free NumRun
run-time program, can be found at www.numerit.com.
The cost of the
source code for this software suite is $129. It can be ordered using the secure and
flexible e-commerce services provided by PayPal
(www.paypal.com).
PayPal accepts online payments by credit card and a PayPal
account is not required to make a purchase. Before purchasing the software, please read
the license
agreement. After
placing your order, you will receive an email within 24 hours with a password
that will permit you to extract the source code and any support data
files. This password protected zipped
file can be downloaded here.
The following text files summarize the
functions available in the Ephemeris and Orbit source code libraries provided
with the purchase of the Orbital Mechanics with Numerit Pro software suite.
