The Research&Design Of Hardware Platform On IFOG Strapdown Inertial Navigation System

As a new fiber optic gyro inertial measurement devices for the strapdown inertialnavigation system has played an important role, it is the small size, high sensitivity, widedynamic range, cost-effective, simple structure, etc. advantages, has been the world’sattention to research institutions and universities have been gradually approachinghigh-precision inertial navigation systems. As a navigation solution processing hardwareplatform is particularly important, a stable performance, high reliability, capacity and strongplatform to simplify the complexity of the system for writing software algorithms to providea convenience.First, you need to understand domestic and strapdown inertial navigation system andhardware platform research projects Research background and significance of thisarrangement the main work; this hardware platform designed for the FOG, FOG need tomaster the basic principles of signal detection and analysis data processing process.Secondly, in a comprehensive understanding of the whole system, the main from thedemand, performance, stability, these three considerations, the design of the hardwareplatform structure of functional modules, to complete the main circuit device selection andthe principle of design,drawing PCB board process, the need to meet the basic requirementsfor electromagnetic compatibility.In the circuit design is complete, you need to write the underlying hardware platformdrivers, to achieve acceleration and gyroscope data, data collection, the data transmissionbetween modules, navigation solver storage, external communication module to receive andsend.Finally, the hardware platform for debugging and general debugging sub-module,according to the system’s functional requirements, write test procedures for the entire systemto verify the basic functionality of the hardware platform, performance and stability.Evaluating the overall system performance, reach a conclusion.
