Abstract:
Based on themathematicmode l o f strap-down inert ia lmeasuring un it ( IMU ) measuring errors, the influence of earth rotat ion angu lar velocity on output of IMU gy roscope and acce lerom eter during error demarcation is analyzed. The IMU error param eters are obtained by operat ing the equat ions of strap-down IMU output in different posit ions to counteract the item s including orientation. The position dem arcat ing method using data processing technique rather than perform ing north precise ly is prov ided in the paper. The demarcation experim ent resu lts show that the method can shor-t en test time and reduce cost of tes.t
