| Abstract: | The Strap-down Inertial Measurement Unit(SIMU)must be calibrated before putting into use to improve its measurement precision and obtain its parameters and performance specifications.A method for calibrating SIMU at all environmental temperature was studied,a special test equipment was used for the calibrating test at all environmental temperature.Static model equations of SIMU were provided,the calibrating method of all parameters in the model equations and the calculating method about error compensation were described in detail.The calculation of the SIMU's synthesis performance specifications was also presented.Lots of SIMUs have been calibrated.The experiment results showed that the applied precision of SIMU was improved effectively by this calibrating method. |
