Aerospace Instrument-Making Annotation << Back Pendulum vertical indicator Y.N. Melnikova, V.Y. Melnikov The possibility of creation of pendulum vertical indicator corrected by accelerometer signals is studied. For the purpose of clearness a singleaxis variant of indicator for which the main regularities are being illustrated is considered. Depending on the class of tasks and the method of forming the correction signal it has certain advantage in accuracy, mass/dimension and power consumption parameters. The indicator is perspective for some applications, particularly, for small-size dynamic objects either as a primary or stand-by attitude indicator.
