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.
Please note that this price does not include the Numerit
Pro computer program. Numerit Pro can be ordered at www.numerit.com.
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.
