| 摘 要： | 以余度捷联惯导系统为研究对象,提出了一种使用余度系统传感器冗余信息对标定结果进行检验的方法.该方法利用已有标定结果对惯性器件进行补偿,然后选取与标定过程不同的敏感轴向组合构建系统并重复标定过程,可以获得标定验证结果.通过对标定验证结果的量级大小进行判断来检测标定结果是否达到预期要求,或者标定过程是否合理.给出了应用该方法的具体过程,通过仿真试验证明该方法的有效性.

| Abstract: | A validation method for calibration results of redundant strapdown inertial navigation systems is presented.After compensating the inertial sensor errors using the existent calibration results,the strapdown system is reconstructed through selecting different sensing axes from those during the calibration procedure,and then the re-calibration procedure is carried out to obtain validation results.Judging from the validation results,the effectiveness of the calibration procedure can be determined.Simulation results are demonstrated to show the efficiency of the proposed validation method. |
