Nov 28, 2017 · In orbital mechanics, the position of a satellite can be defined using orbital elements (which have some advantages over other coordinate systems, for typical orbits). Orbital elements describe a position in relation to the centre of mass of the Earth or any other body. For example, one of the orbital elements is the semimajor axis, which for a ...

Orbital mechanics is a study of second derivatives: F=ma. The directions along the red arrows (v-bar) are useful in orbital mechanics because these are the directions along which you want to thrust to minimize gravity losses. The blue arrows are useful because angular velocity points in this direction. The green arrows?

Mar 26, 2019 · My experience in solving physics problems in mechanics has taught me that energy, linear momentum, or angular momentum are usually the most useful quantities. Delta-v doesn't seem to be a good proxy for any of these quantities, since it's not squared like the kinetic energy, but it's also not a vector like the linear and angular momenta.

Jun 30, 2017 · What is the difference between true anomaly and mean anomaly in orbital mechanics? I want to understand the physical meaning of mean anomaly, for example true anomaly is the angular position of a satellite/object when viewed from earth/focus but what is the corresponding mean anomaly for that true anomaly.

May 4, 2020 · Compute orbital parameters from transverse and radial velocity at a given distance from the focus 3 Calculate velocity vector of elliptical orbit given the position vector at that point, the instantaneous speed, the true anomaly, and the inclination?

Nov 20, 2015 · I've dealt with orbital mechanics in the past but this seems like a whole new ball game. At this point I just need a few numbers to work with (max g load, heat flux and max temp) so that I can use those parameters for material and structural design.

$\begingroup$ Raw distance is a bad metric for collision risk because all distances aren't created equal. This is due to the position covariance (aka position uncertainty) of the objects.

While not a simulator for orbital mechanics, I found this Trajectory Browser from Nasa to be interesting. More game-like is the LEO launcher app and the launch simulator . There's the JPL 3d simulator and the Near-Earth-Object Simulator (both web based).
