In order to improve precision of accelerometer calibration

aiming at certainty error characteristics and engineering installation features of three-axis integration quartz flexible accelerometer

derived and researched

the transformation matrix between accelerometer coordinate system and carrier coordinate system based on transformation of Cartesian coordinate system is deduced. Three quartz flexible accelerometers calibration mathematical models is established. Simulations and navigation experimental result shows that on static conditions error of calibration mathematical model cause velocity error

position error and attitude error; and attitude error and position error contain constant component; all errors contain Schuler Periodic shocks and Foucault Periodic shocks.Foucault Periodic shocks modulate Schuler Periodic shocks.
