    Abstract:
    Within the framework of this work, a comparison of the problem of optimizing the trajectory of a spacecraft with an ideally controlled engine for two- and three-channel control in the vicinity of a circular orbit is proposed. New approaches are introduced to optimize the trajectories of spacecraft in closed form for two- and three-channel control. The Hill-Clohessy-Wiltshire equations are used to describe the motion of the spacecraft in the vicinity of a circular orbit. To solve the optimal control problem, the maximum principle is used. The results of the trajectory optimization problem for two- and three-channel control are compared. Numerical examples of optimal trajectories with an ideally regulated motor in the vicinity of a circular one are given.

    Abstract:
    The monograph clearly shows three parts. The first part contains a vector analysis of a group of equations often referred to as the «Maxwell Equations». Actually one equation belongs to Maxwell's pen, in which he introduced the so-called «bias current». Analysis shows that this current is an extra postscript and interferes with the mutual consistency of the group of equations. Without this current, the wave properties of the electric and magnetic fields disappear. Electric and magnetic fields cease to be a «special form of matter." In the second part, a brief presentation of the fundamentals of new electrodynamics is given, without the Maxwell equation, a group of equations is written, which has no contradictions. The basis is the equation of potentials, the Coulomb law and the laws of the interaction of currents. The theory of radio signal propagation is subject to further development. The last part provides examples of a detailed, complete calculation of the electric and magnetic potentials of typical sources. The monograph is intended for researchers, teachers, graduate students and senior students of technical universities.
