ISS rendezvous launch window

[alternateguru]

Hi
I am currently doing a report on a small RLV. mission objective is to rendezvous with the ISS.
I am using the Chase orbit method, for which the ISS orbit must be directly overhead of the sapce port.
I am looking for a programme or a web site that will allow me to calculate the position of ISS and its trace at any given future date and time.
Given this information i have developed a routine that will calculate lauch window and req azimuth.
The NASA human flight page that i visited only provides this information for past days, i need somthing to plan the launch windows.
Will greatly appreciate a programme

You might try Satellite Tool Kit from AGI as they usually have demo versions that will let you do what you are trying without having to pay for a license. Not sure if you have tried them already. Brian Lewis

No, you have to order the CD, but they'll send it to you for free.

Their CD contains their entire, fully functional software that has a free, but limited, operating mode. The rest of the CD requires purchase of a license.
