Overview on Inertial Measurement Technology for Flight Attitude of Missile

To study trajectory correction,we looked up amount of documents on inertial measurement technology,and had learnt a lot from that.The purpose of the overview is to help readers have a comprehensive understanding of inertial measurement technology.It is suggested that readers start their research with single inertial devices measurement technology and combined inertial measurement unit technology.From early rigid rotor gyroscope to fiber optic gyroscope,from six accelerometers to nine accelerometers which is widely used now,whichever measurement units can't overcome its inherent defects,such as poor measurement accuracy,high cost or poor performance,etc.Combination of different inertial measurement unit techniques may make up for those defects,which based on information fusion technology and complementary characteristic of different inertial devices,which could increase measurement precision,reduce cost and improve performance.
