Whatever his adherence to the Five Percent Nation teachings favoured by the Wu and many of their hip-hop predecessors (the line "Ason, I keep planets in orbit" references both the rapper's Five Percent moniker and the movement's use of the sun to symbolise the black man, viewed as a personification of God), ODB is stretching it when he claims to "drop science like girls be dropping babies".
The GPS time series thus calculated contain significant CMEs, which are considered to be caused by unmodeled, or mismodeled, motions of satellite orbits, reference frame, or earth orientation parameters (Dong et al., 2006).
This paper contributes to the on-going orbit reprocessing carried out by several groups and presents the efforts of the Navigation Support Office at ESA/ESOC using its NAPEOS software for the generation of precise and homogeneous orbits referring to the same reference frame for the altimetry satellites Jason-1 and Jason-2.
As reference orbit, mean orbit elements (original two-lines elements) and osculating orbit elements considering the J2 effect are adopted and compared.
Simulations for various system parameters are conducted for both circular reference orbit and eccentric reference orbit.
Furthermore, by considering time-varying angular velocity of an elliptical reference orbit, the analytical solution of a perturbed orbit radius is obtained in the true anomaly domain.
An analytical solution for the radius of a reference orbit affected by the J2 geopotential disturbance is used to approximate the actual reference orbit rather than directly use the unperturbed standard orbit.
In addition, the actual trajectories of the leader and the follower spacecraft track the periodic reference orbit with high accuracy under the perturbation of the eccentric nature of the Earth's orbit and the initial injection errors.
Thus, emphasis is placed on deducing an accurate analytical solution for a perturbed reference orbit radius, which is analyzed by adding perturbed motion in the radial direction to the corresponding unperturbed reference orbit radius.
The command emphasized that "no object entered orbit," apparently a reference to both the rocket's third stage as well as the supposed satellite.
