Deterministic Analysis of the Effects of Sensor Errors on Strapped-Down INS Performance.
Abstract
The operation of a strapped-down inertial navigation system in a high dynamic environment was simulated. Its performance was assessed using a laser gyro and a quartz-flexure accelerometer as the sensors. Using deterministic values for the sensor errors, the effects of the sensor errors on the INS performance was assessed. Emphasis is placed on the effects that the sensor errors have on the INS errors in a high dynamic environment. Structural mode effects on INS performance are also evaluated. Following this an analysis of the sensitivity of the INS errors in position and velocity to each inertial sensor is determined. Using this sensitivity analysis, the sensor parameters required to obtain a performance specification of < or = 1 nm/hr position error and < or = 3 ft/sec velocity error are defined. Finally, recommendations of areas for improvement are presented. (Author)
