摘　　要：文中首先简要介绍了小卫星的概念和特点,接着分别介绍了当今世界典型的小卫星导航系统GPS和G a lileo系统的概况,阐述了导航定位系统的定位原理和关键技术,最后介绍了三种导航定位新技术:伪卫星技术、小卫星增强GPS技术和GEO卫星辅助的LEO通信小卫星星座定位技术。The concept and characteristics of the small satellite were described firstly. Then the general situation of the GPS system and the Galileo system were generalized, and they are the typical satellite navigation and positioning system in modern times. The principle and the key techniques of the navigation and positioning system were expounded. Finally three new techniques were explained, and they were pseudolite technology, augmentation GPS system by small satellites and LEO communication system positioning technology with the assistance of GEO satellite.
