After trying to create this TLE simulator, I finally came to understand very clearly what RAAN/ascending node, mean anomaly, mean motion, eccentricity, argument of perigee, and so on actually mean. After running the simulator, I also learned why, when observing a satellite’s trajectory—such as that of the Meteor-M2-3 satellite—it sometimes travels from the north, but at other times from the south.
btw i only need 5 minutes to generate this script. lol. we are living in an extraordinary age
i recommend playing this simulator with vertical monitor. so you dont need to scroll up and down when adjust the slider
