We developed the mathematical model of the dynamical testbed assigned for testing accelerometer assemblies. The testbed had a movable platform with one degree of freedom. It can rotate about the axis fixed in a prescribed direction. Tested accelerometer assemblies are placed in the platform that rotates in arbitrary way. Its real motion is reconstructed a posteriori by measurements of vision system. The reconstruction is carried out in digital form and allows to calculate real accelerations felt by the assemblies. The calculated accelerations are compared with measured ones. The comparison results used in testing and calibration of sensors, electronic units, etc.
