Abstract Conning error is a principle error of strapdown attitude algorithm, which degrades the attitude
precision greatly. To three-axis laser SINS, besides the conning motion introduced by carrier, there are conning
motion introduced by dithering of three-axis laser gyro. The cause of two kinds of conning motion is analyzed,
and the application result of conning error compensation algorithm in different test environment is described.
Key words SINS; conning error; attitude algorithm; FOG
