The possibility of manufacturing compact accelerometer based on prefabricated elements has been shown. Since most of the sensitive element designs at the lowest cost possible to produce at different ranges of sensitivity, so accelerometer design will be flexible in terms of wide range measuring of linear accelerations. Paper describes an original method of calibrating an autonomous unit of accelerometers. Without the use of precision rotary tables, centrifuges, and independent of the vibration reason, it is possible to reduce the error caused by the mismatch (not orthogonal) of sensor?s axes. Zero and scale factors of the sensor unit are calibrated with great precision. The calibration of the sensor unit with a measuring range of 2 g, produces the following results: the standard deviation of the vector g, measured in more than 100 different static positions is less than 0.001 g. The way of real sensors noise parameters accommodation under the strap down inertial navigation systems mathematical simulation is offered. The sensors output signal noises components both separate and aggregate influence on the strap down inertial navigation system accuracy is shown.
