北斗二号双模型用户机的设计实现

摘要

Based on BeiDou double model receiver development as the background,this paper firstly introduces the operating principle and composition of BeiDou double model receiver, and then describes the overall scheme design mainly from the hardware design and the software design.Then the key technologies are described in this paper involve four designs, that are sensitivity, harvesting policy, navigation text processing policy and low power consumption.And finally the experiment conclusions and test results are given in the paper.%论文以北斗双模型用户机研制为背景,介绍了北斗双模型用户机的工作原理和组成,并详细介绍了总体设计方案,包括硬件方案、软件方案.然后从灵敏度、捕获策略、导航电文处理策略、低功耗设计等四个方面解释了关键技术,最后给出实验结论及测试结果.
