| Abstract: |
| With the development of microelectronics technology and Micro-Electro-Mechanical System(MEMS), especially MEMS inertial technology, more and more low-cost, small-size, high-performance GNC products are applied to micro unmanned aerial vehicles, unmanned ground system, precision guided munitions and other fields. In order to meet the requirements of applications, using MEMS Inertial Measurement Unit(IＭU), GNSS receiver, all strapdown infrared,visible light, laser multi-mode intelligent seeker, Digital Signal Processing(DSP) and datalink communication, a System in Package(SiP) technology is applied to construct the micro GNC system. The key technologies such as micro GNC system integration based on SiP, multi-mode intelligent seeker, embedded ultra-tightly integrated navigation, and integrated design of intelligent seeker and GNC have been broken through. A test system for micro GNC system is developed and the performance of the micro GNC system is evaluated. Micro GNC system technology provides a technical foundation for the development of unmanned system and precision guided munition. |
