摘要
设计开发了BDS/GPS双系统五频点高精度接收机,其能为用户提供水平定位精度2 cm的位置服务,可广泛应用于林区规划、巡护、资源调查、火灾监测等领域。本方案的基带处理器和导航信息处理器采用内置双核ARM的FPGA相对传统的DSP+FPGA设计方案,可大大节省硬件面积,降低功耗。经实验验证,该接收机能够稳定地提供厘米级的位置信息服务。
A high-precision receiver with five-points of BDS/GPS dual-system is designed and developed,and it can provide users with location services with horizontal positioning accuracy of 2 cm and can be widely used in planning,patrol,resource investigation and fire monitoring fields in forest areas. The relative traditional DSP ＋ FPGA design scheme of FPGA with built-in dual-core ARM is adopted for the baseband processor and the navigation information processor of this scheme,which can greatly save hardware area and reduce power consumption. The experimental verification proves that the centimeter-level location information services can be stably provided by the receiver.
