| 摘 要： | CC2431是TI公司推出的一款带定位引擎的片上系统芯片。本文详细介绍了CC2431无线定位系统的工作流程以及RSSI定位原理，针对CC2431无线定位引擎只能进行二维定位的不足之处，提出了将CC2431无线定位引擎与三角测量法相结合的改进方法，实验表明这种改进后的方法在实现三维定位的同时，也提高了定位精度。

| Abstract: | CC2431 is a SOC （system - on - chip） chip with positioning engine which the TI company protrusived. This paper described the CC2431 wireless orientation system working process as well as the RSSI positioning principle, aim at the CC2431 wireless positioning engine can only be two - dimensional located , this paper put forward a improved method that combined the CC2431 wireless positioning engine with the triangulation, experiments showed that this improved method can achieve three - dimensional orientation, and also improve location accuracy. |
