Numerical Orbit Propagation Methods
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
Numerical orbit propagation methods are computational algorithms used to predict the future position and velocity of celestial bodies or artificial satellites based on initial conditions and gravitational or non-gravitational forces. These methods involve numerically solving the governing differential equations of motion, enabling accurate tracking of an object’s trajectory over time, which is essential for space mission planning, satellite operation, and collision avoidance.
