【摘要】 随着移动定位技术的发展,单纯的基于GPS的定位终端或者基于移动网络的定位终端都将无法满足用户的需求。前者的GPS定位信号受地形及建筑物的影响,会存在定位盲区;后者定位精度和定位能力受到移动网络的限制。该文提出一种集成了GPS定位和GSM网络定位技术的定位终端,阐述了它的软硬件的设计和实现。实验结果表明,该定位终端结合了GPS和GSM网络两种定位方式的优点,定位性能大大提高。更多还原

【Abstract】 The tracking terminal plays an important role in the navigation and positioning system. How to improve the performance and precisionof the tracking terminal is a key problem to the designer and user. This paper presents a method which integrates GPS with GSM positioningtechnology in one terminal, and specifies the software and hardware design and implementation of the terminal.更多还原
