orbitalmanövrar

Orbitalmanövrar, often referred to as orbital maneuvers, are the processes used to change the orbit of a spacecraft. These changes are achieved by expending propellant to alter the spacecraft's velocity. The fundamental principle behind orbital maneuvers is Newton's laws of motion, specifically the concept that an object in motion will stay in motion unless acted upon by an external force. In space, the primary means of applying this force is through the firing of rocket engines.

The most common type of orbital maneuver is a thrust applied tangentially to the orbit. A thrust in the direction of the spacecraft's motion increases its orbital energy and raises its altitude. Conversely, a thrust against the direction of motion decreases its orbital energy and lowers its altitude. These maneuvers are crucial for tasks such as transferring between orbits, such as moving from a low Earth orbit to a geostationary orbit, or for rendezvous and docking with other spacecraft.

Other types of orbital maneuvers include out-of-plane maneuvers, which change the inclination of the orbit, and radial maneuvers, which change the eccentricity. Precise calculation and execution of these maneuvers are essential for mission success, as even small errors can lead to significant deviations from the intended trajectory. Spacecraft systems dedicated to maneuvering, including thrusters, propellant tanks, and guidance computers, are vital components of any space mission.
