介绍了一种ICS公司生产的高速数据采集卡ICS554在室内GPS中频数据采集中的典型应用.采集后的信号经过PCI总线模块后,数据被上传到PC机进行数据存储,实现了室内GPS中频信号的数字化采集.实验结果表明,室内外两路天线的设计有利于适合室内环境下的需求,同时通过PCI总线可以将采集数据实时高速地传输到PC机,有助于后续对室内信道特性的数据建模和研究.%A typical application of high speed data acquisition card ICS554 produced by ICS corporation in indoor GPS IF (intermediate frequency) signal digital collection is introduced. The output signal after PCI bus module, data are uploaded to PC and storage, realize the indoor GPS signal of IF digital collection. Experimental results show that design of inside and outside antennas is suitable for indoor environment, and can transmit highspeed real-time acquisition data to the PC through PCI bus and help to follow-up data modeling and research on indoor channel characteristic.
