A test bench is proposed, consisting of three pairs of mutually perpendicular coils and a control unit with software. The task of the stand is to simulate the change in the Earth's magnetic field when the spacecraft moves in orbit in order to work out the algorithms for the operation of the angular orientation and stabilization system of the spacecraft. The system has six independent coils, which have different parameters due to the design features. The article describes the calculation of the number of turns and the choice of the diameter of the wire of the coils, the calculation of the current and supply voltage to maintain the required number of ampere-turns, the choice of the geometric configuration and the calculation of the geometric parameters of the coils, as well as the block diagram and description of the control unit. This system is capable of providing a field strength five times that of the Earth. The degree of inhomogeneity of the modulus of the field strength does not exceed 1% in a sphere with a radius of 150 mm, which corresponds to the calculated data. The control unit supports manual control of each pair of coils, changing the magnetic field strength, and also provides current and magnetic field stabilization using current sensors and a magnetometer suspended on a tripod. The control unit has overcurrent and overvoltage protection, as well as short circuit protection. The output stages of the control unit are implemented according to the H-bridge scheme. The software allows you to control the control unit in manual and automatic modes using the model of the Earth's magnetic field, thereby simulating the magnetic field, taking into account the nature of the spacecraft movement, which allows you to more accurately determine the characteristics of the angular orientation and stabilization system.
