Trajectory

View this topic in
A trajectory is the path that a moving object follows through space as a function of time. The object might be a projectile or a satellite, for example. It thus includes the meaning of orbit—the path of a planet, an asteroid or a comet as it travels around a central mass. (Wikipedia.org)

  • Satellite Orbits and Trajectories

    The study of orbits and trajectories of satellites and satellite launch vehicles is the most fundamental topic of the subject of satellite technology. An understanding of the orbital dynamics would give a sound footing to address issues like types of orbit and their suitability for a given application, orbit stabilization, orbit correction and station keeping, launch requirements and typical launch trajectories. This chapter focuses on all these issues and illustrates various concepts with the help of necessary mathematics and a large number of solved problems. The motion of natural and artificial satellites around Earth is governed by centripetal force and centrifugal force, which are explained in the chapter from Newton's laws and Kepler's laws. The horizontal velocity with which a satellite is injected into space by the launch vehicle with the intention of imparting a specific trajectory to the satellite has a direct bearing on the satellite trajectory.

  • The 2D Nonpenetrable Parallel Plate Waveguide

    This chapter deals with high frequency electromagnetic wave propagation in guiding environments. After an introductory overview of issues and physical interpretations pertaining to this broad subject area, detailed attention is given to the simplest canonical, thoroughly familiar, test environment: a (time-harmonic) line-source-excited two-dimensional (2D) infinite waveguide with perfectly electrical conducting (PEC) plane-parallel boundaries. After formulating the Green's function (GF) problem within the framework of Maxwell equations, alternative field representations are presented and interpreted in physical terms, highlighting two complementary phenomenologies: progressing (ray-type) and oscillatory (mode-type), culminating in the self-consistent hybrid ray-mode scheme which is usually not included in conventional treatments at this level. This provides the analytical background for two educational MATLAB packages which explore the dynamics of ray fields, mode fields, and the ray-mode interplay: RAYMODE package and HYBRID package. Finally, the chapter focuses on eigenvalue extraction from propagation characteristics and tilted beam excitation.

  • Force and Torque

    In this chapter, an energy-based approach to the calculation of force and torque is set forth. Two variations of the approach are considered. In the first variation a macroscopic view of the device is taken. The second variation of the approach views the device microscopically. The chapter focuses on the evaluation of an expression for the energy in the coupling field. Once an expression for field energy has been derived an expression for force is readily obtained. The chapter considers the more common case where flux linkage is expressed as a function of current and position. It also shows that the co-energy provides a useful vehicle in the calculation of force. The chapter also considers a microscopic device view in which the flux linkage equations need not be explicitly formulated. This approach facilitates the calculation of force or torque when using magnetic equivalent circuit analysis.

    A general consensus tracking problem is formulated for a global Lipschitz group. A distributed and optimal D¿¿¿type ILC is developed to achieve perfect consensus tracking.

  • SATELLITE ORBITS

    This chapter considers the analysis and characterization of satellite orbits based on Newton's laws of motion, his law of universal gravitation, and Kepler's laws of planetary motion. It applies these laws to the Earth's elliptical satellite orbits with the Earth at one focus; the circular orbit being a special case. The emphasis is on characterizing communication links between the Earth and various satellites and crosslinks between satellites. In addition to elliptical satellite orbits, the results also apply to ballistic missile trajectories. The chapter evaluates the range, range‐rate (velocity), and acceleration along the line of sight (LOS) between a satellite and ground station and characterizes the range, Doppler, and Doppler rate based on the results. The Earth stations are defined in terms of their latitude and longitude with respect to the Earth‐centered Earth‐fixed coordinate system. The location of a satellite in its orbital is determined using the six orbital parameters.

  • Intent Inference and Detection of Anomalous Trajectories: A Metalevel Tracking Approach

    Classical target tracking assumes a state¿¿¿space model with target maneuvers modeled as a finite state Markov chain. This chapter motivates by metalevel target tracking applications on longer time scales. It develops metalevel tracking algorithms that assist human operators by extracting spatial patterns from target tracks to identify suspicious/anomalous spatial trajectories. The targets' spatial trajectories are modeled by two types of random processes: stochastic context¿¿¿free grammars (SCFGs); and reciprocal random processes. The chapter presents Bayesian filtering and smoothing algorithms for these processes to estimate the trajectories and hence intent of the targets. It describes a system¿¿¿level description of the anomalous trajectory classification problem, discusses the radar tracking framework and provides a mathematical description of trajectory classification. The chapter presents SCFG models and associated signal processing algorithms for trajectory modeling and classification. It considers reciprocal processes for modeling target intent. The parsing of the motion trajectories is implemented with Earley¿¿¿Stolcke parsing algorithm.

  • Iterative Learning Control for Multi¿¿¿agent Coordination Under Iteration¿¿¿Varying Graph
