所需导航性能 meaning in Chinese

requied navigaton performance

With argumentation system and differential system , gnss is capable of supporting en route flight and cat iii precision approach . this system can meet the need of all flight phases in terms of integrity , precision and continuity . with the application of area navigation and required navigation performance ( rnp ) , this would make the parallel route , random route and direct flight route possible , and also improves the efficiency of air space and the flight safety
在导航系统中，全球卫星导航系统是其主要成分，通过增强系统和差分技术， gnss具有支持从航路飞行到类精密进近的能力，在完好性、精度、可用性、连续性上都可以满足飞行各阶段的要求；随着区域导航和所需导航性能的实施，平行航路、随机航路和起点和终点之间的大圆航线直飞得以实现，提高了空域利用率和飞行安全。
