Orbital Mechanics Fundamentals
Orbital mechanics is the study of the motion of objects in space. It is a branch of physics that deals with the laws of motion and the forces that act on objects in orbit. Orbital mechanics is used to design and control the trajectories of spacecraft, satellites, and other objects in space.
The basic concepts of orbital mechanics are Kepler’s laws and Newton’s laws of motion. Kepler’s laws describe the shape and size of orbits, while Newton’s laws of motion describe the forces that act on objects in orbit.
Kepler’s laws are as follows:
- The orbit of a planet is an ellipse, with the sun at one focus.
- The line connecting a planet to the sun sweeps out equal areas in equal time intervals.
- The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit.
Newton’s laws of motion are as follows:
- An object at rest will remain at rest unless acted on by an unbalanced force.
- An object in motion will continue to move in a straight line at a constant velocity unless acted on by an unbalanced force.
- For every action, there is an equal and opposite reaction.
Orbital Maneuvers
Orbital maneuvers are changes in the trajectory of a spacecraft. They are used to correct the spacecraft’s orbit, to rendezvous with another spacecraft, or to change the spacecraft’s mission.
There are many different types of orbital maneuvers, but the most common are Hohmann transfers and rendezvous maneuvers.
Hohmann transfers are used to change the orbit of a spacecraft from one circular orbit to another circular orbit. They are named after Walter Hohmann, who first described them in 1925.
Rendezvous maneuvers are used to change the orbit of a spacecraft so that it meets another spacecraft. They are used to dock with space stations, to repair satellites, or to transfer crew members between spacecraft.
Orbital maneuvers are challenging and require careful planning and execution. The spacecraft must be precisely controlled to ensure that it follows the desired trajectory.
Satellite Dynamics
Satellite dynamics is the study of the forces that act on satellites in orbit. These forces include gravity, drag, and radiation.
Gravity is the primary force that keeps satellites in orbit. It is the force of attraction between two objects with mass. The greater the mass of the objects, the greater the force of gravity.
Drag is the force that opposes the motion of a satellite through the atmosphere. It is caused by the collision of the satellite with molecules of gas in the atmosphere.
Radiation is the force that is exerted by electromagnetic waves. It can cause damage to the satellite’s electronics and solar panels.
The effects of gravity, drag, and radiation can be used to control and maintain satellites in orbit.
Mission Design
Mission design is the process of designing a spacecraft mission. It includes the selection of an orbit, the determination of launch parameters, and the design of the spacecraft.
The orbit of a spacecraft is determined by its mission objectives. The launch parameters are determined by the orbit and the spacecraft’s mass and performance.
The spacecraft is designed to meet the mission objectives and the launch parameters. It must be able to withstand the forces that it will encounter in orbit and it must be able to perform the mission tasks.
Orbital mechanics is used in all aspects of mission design. It is used to select the orbit, to determine the launch parameters, and to design the spacecraft.
