Considered electric propulsion systems (EPS) based on the Hall effect. Structure of EPS includes hall thruster (HT), xenon feed system (XFS), power processing unit and automatic control and monitoring system. The task is to design information-measuring system (IMS), which allows measurement of the current settings of EPS, conduct their mathematical processing and registration for further analysis. EPS is a complex physical system consisting of subsystems within which different physical processes. These processes are characterized by a large number of parameters and characteristics to be measured and controlled in the process EPS. Listed EPS parameters that should be measured in the operation of system. Determined informative signs of laboratory and onboard subsystems EPS. The necessity of development of information-measuring system and the need to create two different IMS - for use in laboratory equipment for research and testing of subsystems and EPS use in an onboard system management and control. Laboratory IMS provides measurement parameters and test conditions in a vacuum chamber; modes of power processing unit; XFS modes; EPS temperatures subsystem (anode, cathode, supply system, power conversion system); thrust of hall-effect thruster and forming control signals for power sources, flow of propellant and laboratory equipment. Onboard IMS provides measuring current and voltage discharge between the anode and the cathode; valve current of XFS; high and low level pressure of XFS; the temperature of the anode block, cathode, power processing unit.Formulated the tasks performed by the laboratory and on-board IMS. Made choice of hardware implementation of the IMS. The work on the creation of software for the operation of the IMS.
