Patent ID: 8670964

Claim:
A gyrocompass modeling and simulation (GMSS) system for a gyrocompass, comprising: a computer executing the following simulators and modules; a six-degrees-of-freedom (6DOF) motion simulator; an inertial measurement unit (IMU) sensor simulator which comprises real-time sensor data acquisition and modeling tools; a gyrocompass system and calibration process simulator; and a gyrocompass system evaluation and analysis module, wherein said 6DOF motion simulator, said IMU sensor simulator, said gyrocompass system and calibration process simulator and said gyrocompass system evaluation and analysis module are interlinked through an accumulative communication stream; a translational motion simulator communicated with said IMU sensor simulator, wherein said translational motion simulator comprises: a module representing mass of a unit model, modules representing kinematic constraints of a translational motion, a module of three-dimensional translational motion controller controlling said translational motion according to input motion commands, a module of input and output (I/O) interface programs converting user inputs from an input device to a real-time data stream, a module of stochastic signal generators producing random forces, a module of statistical parameter controller controlling the stochastic signal generators and setting statistical parameters, a module of graphic user interface (GUI) or Window for program control and configuration and data visualization and display, and a module of motion script editor or translator for an optional function of said module of motion script editor or translator for translating a text or script description of said motion commands to a data stream for simulation.
