Attitude error models play an important role in analyzing the characteristics of navigation propagation for design and operation strapdown inertial systems (SINS). However, majority existing attitude focus on misalignment, rather than Euler angle errors. Misalignment cannot directly describe propagation, which is indirect measurement. To solve problem, a general model SINS proposed. Based analysis, relative errors, convected errors are introduced to compose model. Simulation experiments carried out verify proposed
