[Orekit Users] SFDaaS : Space Flight Dynamics as a Service

[<haisam.ido@gmail.com>]

This may be of interest to others.  I've added my crude Space Flight Dynamics
as a Service (SFDaaS) application on GitHub here
https://github.com/haisam/SFDaaS . 

Currently, its only capability is to propagate state forwards or backwards in
time using the http://orekit.org Java library.


Requirements:

 * Eclipse IDE
 * Tomcat 6.0
 * apache.commons.math (included)


Usage:

http://localhost:8080/SFDaaS/PropagateServlets?t0=2010-05-28T12:00:00.000&tf=2010-05-29T12:00:00.000&r0=[3198022.67,2901879.73,5142928.95]&v0=[-6129.640631,4489.647187,1284.511245]



Output: 

-------------------------------------------------------------------------------------
Run Start : 2011-10-07T23:48:48.894-0400 
Run End : 2011-10-07T23:48:48.907-0400 

A priori state : 
Epoch = 2010-05-28T12:00:00.000 
r = [3198022.67,2901879.73,5142928.95] 
v = [-6129.640631,4489.647187,1284.511245] 


Posteriori state : 
Epoch = 2010-05-29T12:00:00.000 
r = [5630517.796159,-3606350.100536,-606046.049292627] 
v = [3048.698685,3756.457104,6000.256417807639] 

The epochs are assumed to be UTC and r0 and v0 are in meters and in the J2000
Earth-centered frame.
