GUO Qing-ye, YU Zhi-wei, LIU Ming, et al. Study of impact of odometer precision on INS platform error model identification[J]. 2008, 27(10): 30-32. DOI: 10.13873/j.1000-97872008.10.002.
The precision of odometer impacts platform error model identification precision directly when doing the error model identification based on the test of vehicle.INS platform error model is given and the measuring error equation about apparent velocity is established.The system exists serious multi-colinearity because of the size of the input acceleration.The pivoting least squares method is used in the INS platform error model identification.The simulation results provide the impact of odometer precision on INS platform error model identification precision.
