Simulation of Geosynchronous Satellite Launch Process

Geosynchronous satellite launch process simulation is a classic numerical simulation case in astrodynamics. Implementing this process with MATLAB helps in understanding fundamental orbital mechanics principles and programming techniques.

The simulation consists of several key phases: first, the vertical rocket launch phase where the balance between Earth's gravity and rocket thrust must be considered; followed by the gravity turn phase where the rocket gradually changes attitude to enter inclined flight; and finally, the Hohmann transfer orbit phase that transfers the satellite from its initial orbit to the geosynchronous orbit.

In MATLAB implementation, numerical integration methods (such as Runge-Kutta algorithms) are typically employed to solve satellite motion equations. These equations incorporate Newton's laws of motion and the law of universal gravitation, while also accounting for factors like Earth's non-spherical perturbations and atmospheric drag. By adjusting thrust magnitude, direction, and timing, the launch trajectory can be optimized to ensure precise satellite insertion into the target orbit.

This simulation not only demonstrates orbital mechanics principles but also helps understand MATLAB applications in scientific computing, including differential equation solving, 3D visualization capabilities, and numerical analysis tools. It serves as an excellent learning case for aerospace enthusiasts and STEM students, providing hands-on experience with orbit propagation algorithms and spacecraft dynamics modeling techniques.
