In fusion research Runge Kutta methods are frequently used for guiding center orbit following codes.
The technology can also be used for thrusters on Earth-orbiting satellites.
This particular orbit is used for meteorological and communications satellites.
Sagittal reconstructed images created vertical to the orbit were used for measurements.
Different GCD versions exist depending on the orbits that are used for constructing the matrices: (i) GCD-73 accounts for the complete set of 73 orbits from all 2- to 5-node graphlets and (ii) GCD-11 accounts for 11 non-redundant orbits of 2- to 4-node graphlets (i.e. orbits 0, 1, 2, 4, 5, 6, 7, 8, 9, 10, 11).
To take into account the symmetry groups within a graphlet, the notion of automorphism orbits (or just orbits, for brevity) is used for all graphlets with 2-5-nodes.
Precise orbit data are used for all the interferograms.
In 1919 Pickering also predicted the existence of, and gave a position for, an object orbiting beyond Neptune.
If, for instance, an object orbits the Sun twice for every three Neptune orbits, and if it reaches perihelion with Neptune a quarter of an orbit away from it, then whenever it returns to perihelion, Neptune will always be in about the same relative position as it began, because it will have completed 1½ orbits in the same time.
If, say, an object orbits the Sun once for every two Neptune orbits, it will only complete half an orbit by the time Neptune returns to its original position.
