Error analysis of space stabilized strap-down inertial navigation system on stationary base

  • Received Date: 01 Jun 2011

  • In order to satisfy the technical index of strap-down inertial navigation system and the precision of inertial components, the error propagation characteristics of the space stabilized strap-down inertial navigation system have been analyzed. The scheme of space stabilized inertial navigation system was proposed. According to the analysis of stationary base error equations, the impacts of gyro drift and accelerometer errors on space stabilized inertial navigation system were researched. Theoretical analysis and the experiment show that, the longitude error increased gradually based on the gyro constant drift, the other parameters accumulated base on the Schuler and Earth circle.
