摘要: In order to solve the strapdown inertial navigation system (INS) alignment problem under marine mooring condition, rapid INS fine method is proposed. This uses gravity in frame deal with lineal and angular disturbances. Also forward backward processes for calculation filter estimation are designed. Making use of repeatedly process saved measurement unit (IMU) data sequence could quickly obtain initial attitude matrix. Simulation trial test validate performance proposed alignment.
