Flight Test Results of the Six-Axis Unit of Apparent Acceleration Meters Based on a Precision Quartz Pendulum Accelerometer with Digital Feedback as Part of the Soyuz MS-14 Spacecraft

The report reviews the flight test results of the unit of linear acceleration meters (the BILU device) built on quartz pendulum accelerometers with digital feedback amplifier and pulse-width electric current control of torque sensor of each measuring channel. The unit has passed the flight tests as part of the control system of the Soyuz MS-14 spacecraft. A number of topics is considered, including the results of flight tests themselves, as well as the result of the analysis of the BILU device parameters after the tests, which confirm the stability of the main technical characteristics of the device.
