Abstract

The article proposes a variant of constructing a digital system for automatic stabilization of the antenna field platform located on an object (vehicle), and also considers the structural diagrams of control channels. The choice of executive devices to ensure the performance and accuracy of the system is substantiated. The conditions of use, restrictions and initial data necessary for the synthesis of the automatic stabilization system are determined, the principles of calculating by the system - the coordinates of the position of the antenna field platform in space - are highlighted.The prerequisites for the use of a platform with stabilization at the facility is the need to ensure the most efficient use of communication facilities (antenna systems) in a complex electromagnetic environment and to reduce the deployment (folding) time, adjust radio and satellite communications in the operational-tactical and tactical control levels.The system of automatic stabilization of the antenna field platform will provide optimal conditions for the interaction of antenna systems that are part of the antenna field of radio-electronic means of the compact constellation. Optimal conditions should be understood as vertical placement of omnidirectional antennas, the possibility of changing the position of directional antennas in the azimuthal plane and ensuring the electromagnetic compatibility of radio electronic means. The deviation of the platform from the required angular positions of the reference coordinate system can be determined by accelerometers or other devices that measure the linear acceleration of an object in a given plane.It is proposed to stabilize the platform through two channels for each of the axes. The angular position of the stabilized platform in space is specified in the reference coordinate system, which is not associated with a moving object (vehicle) that is moving, and in a moving coordinate system, it is rigidly connected with this object. It is proposed to use an inertial coordinate system as a reference coordinate system, that is, motionless relative to the horizon, which is oriented at a given point on the earth's surface. The proposed automatic system is universal, with the ability to adapt to the driving performance of a moving object. Adaptability is ensured by the presence in the control loop of an automatic stabilization system of circuits, the parameters of the transfer functions of which are pre-calculated for the tactical and technical characteristics of the moving object.
