Satellite Motion

[ahmedelshfie]

This applet is other version from Satellite Motion, the original applet created by prof Hwang, modified by Ahmed.

The applet modified by request of Satellite Motion applet from a user.

Well this applet design by Ahmed using knowledge, variables and equations prof Hwang.

Enjoy

Here some images to help for who interesting about Satellite Motion.

I receive E-mail from prof Wolfgang Christian about Satellite motion applet, i was already contact OSP to if may they like to post the applet that i modified in their website, i need to understand how to modified the applet to be like what Wolfgang Christian suggest, here the E-mail.

Dear Ahmed—

Thank you for sending me your model.

The applet is very nice and shows how to include images in EJS model.  The images add a lot of realism but this realism may suggest that the scale is correct.  I am worried about the incorrect scale of the satellite image relative to the Earth and the orbital radius of the satellite.  Also, the axis of rotation is not the North Pole.

I need help to understand this part

I am worried about the incorrect scale of the satellite image relative to the Earth and the orbital radius of the satellite.  Also, the axis of rotation is not the North Pole.

Thanks in advance

there are some physics issues with the remixed version above.
the time is not in units i can associate with .
dc/dt = 2*pi/24
assumes t is in hours

u can look at my simulation here http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=2204.0 which i have made the velocity and radius of planet to scale.

the axis of rotation u need to find an image taken from the axis of rotation, instead of the north pole.
it is slightly off from the north pole.
u can try to make one from google earth.
good luck

You can drag the satellite and simulate different trajectory.
You can also check the show velocity to change the velocity,too!

I just modify the satellite image (set draggable to true)!
