一种新式飞机导航系统可望广泛用在军用飞机上,它把惯性技术和全球定位技术结合起来,以便发挥各自独特的优势。由于GPS接收机的尺寸显著减小及环形激光陀螺技术的发展,这种嵌入式GPS惯性系统(EGI)已成为可能,并可能使这种EGI系统的质量不到11.340kg,约为常规惯性系统与原有GPS接收机不组合在一起时总质量的1/4。除了尺寸小、质量轻和功耗低外,EGI系统能够为军用飞机提供加密的P码信号。
A new type of aircraft navigation system is expected to be widely used in military aircraft. It combines inertial technology with global positioning technology to exert its own unique advantages. Due to the significant reduction in size of the GPS receiver and the development of ring laser gyroscope technology, this embedded GPS inertial system (EGI) has become possible and may make this EGI system less than 11.340 kg in mass, about the conventional inertial system With the original GPS receiver is not combined with the total mass of 1/4. In addition to its small size, light weight and low power consumption, the EGI system provides encrypted P-code signals for military aircraft.
