Displacement Calculation and Simulation Study under Body Frame System

Inertial strapdown navigation system is a system based on Newtonian mechanical principles for navigation data acquisition, and has a very wide range of applications in ships and other fields. Since the inertial strapdown navigation system is coupled with the movement of the carrier during the working process, therefore, the error analysis and measurement parameter calibration of the inertial strapdown navigation system are very important, among which the conversion of latitude and longitude into the displacement under the carrier coordinate system is an important problem in the solution of inertial conduction position information, this paper derives the conversion process with a strict formula, and compares with the actual data through experimental simulation to verify the correctness of the process.
