On the Problem of Testing a Portable Acceleration Recorder under Orbital Flight Conditions.

The paper discusses the possibility of testing and correcting calibration of a portable acceleration recorder under orbital flight conditions. This recorder in-cludes a 3-axis accelerometer. The most difficult stage of calibration tests is the determination of its scale factors. The main difficulty of calibration is the lack of special equipment on the space station. It is proposed to use a standard mass meter installed on the ISS for testing accelerometers. The algorithms considered in the paper use data of the motion of the mass meter platform and the video camera records processing in addition to the recorder readings. For testing the algorithms under earth conditions, recordings were made that simulate conditions of an orbital flight. The proposed algorithms showed 2 % error in determining the scale factors of the accelerometers.
