    evaluate my brand new program! :) satelite motion around earth!


    finally I managed to create a working version of my prog :)

    with the help of my friend, and physics teacher (he corrected couple of -/+ :)) I created the very first, user friendly prog...

    that's beta release and it still needs a lot of work, but still check this out! :)


    and yeh, can anyone tell me why those orbits don't match? I mean that slight difference? strange I guess... :eek:

    (and yes, please use recommended values :devil: )

    for deriving my algorithm, I used Newton's II law...

    you can download program from here: http://sandro-dz.com/satmotion.zip [Broken]

    btw. www.sandro-dz.com[/URL] is my homepage :)

    Well I downloaded it and had a look and nothing worked....

    I put in the values suggested (why not have them as a default setting?), but nothing happened... What is the top Delta value box for? I couldn't type anything in there.

    I have no idea why it didn't work... Was I supposed to 'do' something else?

    delta T is the second field, if u do not enter that number it will not work! use the second field, bellow!

    i pressed go, the sattelite started moving then pressed go again and it stoped (but I mean really stopped, i had to restart the program to run again)

    I think you should do as Adrian said and put those values as default

    I didn't vote in the poll, because theare are too few options... :wink:

    and donwload the newer version...I updated couple of things! http://sandro-dz.com/satmotion2.zip [Broken]

    :yuck: :yuck:
    ::Delta T 0.09, velocity 30 and mass 150, this are the best values for maintaining thie real kind orbit!::

    :approve: :approve:

    and also check this pics, here are the strange orbits! :surprise:

    I think I need a refresh button :)
