- Special Orbits — Introduction to Spacecraft Dynamics
Almost polar orbits that are good for global mapping (Typical inclination at Low Earth Orbits) Retrograde for constant illumination condition Typical inclination at Low Earth Orbits Repeat Groundtrack Orbits # This Orbit is designed such that the groundtrack repeats after n orbits and m days often to access the same targets

Here are the important mission requirements Orbital altitude, h Orbital inclination, i Equatorial orbit: zero degrees of inclination Polar orbit: 90 degrees of inclination Launch latitude Let’s consider the components of the Delta V requirement Orbital velocity (Kinetic energy component) (reversible)
- What are the typical values of the orbital inclination angle (i) used . . .
Typical Orbital Inclination Angles for Sun-Synchronous Orbits (SSO) Sun-synchronous orbits are prized for their consistent lighting conditions, making them ideal for Earth observation, remote sensing, and weather monitoring The inclination angle (i) is the key parameter defining a SSO, and it's not a single value It's carefully chosen based on several factors, primarily the desired latitude

Inclination is the angle of the orbit in relation to Earth’s equator A satellite that orbits directly above the equator has zero inclination If a satellite orbits from the north pole (geographic, not magnetic) to the south pole, its inclination is 90 degrees Orbital inclination is the angle between the plane of an orbit and the equator

Orbital inclination changes: The Hohmann and bi-elliptic transfers are useful for orbits in the same plane, but what if we want to increase orbital inclination? These require much more energy, but can be done with an upward or downward thrust perpendicular to the existing orbital plane at one of the nodes

The path that a satellite has to travel to stay in a Sun-synchronous orbit is very narrow If a satellite is at a height of 100 kilometers, it must have an orbital inclination of 96 degrees to maintain a Sun-synchronous orbit Any deviation in height or inclination will take the satellite out of a Sun-synchronous orbit

Combinations of non-zero inclination and eccentricity will all result in movement relative to a fixed ground point Figure 3 shows some typical results The figure-eight ground track is that of the geosynchronous orbit (GEO) shown in Figure 2 The geostationary satellite (GSO) sits fixed at the crossover point of the figure eight (over the

Video 3: Simple Plane Change Inclination (George, 2023) CHANGING RAAN Changing RAAN is very similar Much like how the Simple plane change has to be performed over the ascending or descending node for inclination, a Simple plane change of only RAAN can only be performed above the North or South Pole because the orbital swivel, or RAAN, rotates about the line connecting the poles, or the Earth
