A Real-Time Capable Software-Defined Receiver Using GPU for Adaptive Anti-Jam GPS Sensors
Global Positioning System (GPS) sensor software-defined radio controlled reception pattern antenna (CRPA)
2015/6/24
Due to their weak received signal power, Global Positioning System (GPS) signals are vulnerable to radio frequency interference. Adaptive beam and null steering of the gain pattern of a GPS antenna ar...
在较大初始姿态误差角下,针对SINS/GPS紧组合导航系统扩展卡尔曼滤波(extenthed Kalman filter, EKF)算法定位精度下降的问题,提出了一种基于四元数的平方根无迹卡尔曼滤波(square root unscented Kalman filter, SRUKF)算法。为解决SRUKF算法中四元数正交规范化的限制,通过构造姿态矩阵代价函数将四元数预测均值问题转化为代价函数最小...
基于NTRIP协议的虚拟差分GPS接收设备设计(Development of a GPS Receiver Based on NTRIP/VRS)
全球定位系统 虚拟参考站技术 NTRIP协议
2009/11/3
在分析NTRIP(networked transport of RTCM via Internet protocol)协议组成及特点的基础上,针对低成本、低精度的GPS OEM板,采用GPRS无线通信方式,设计开发了手持式虚拟差分GPS接收设备,并进行了试验验证。开发的接收设备是以ARM7为核心,包括无线通信模块、GPS OEM板、液晶显示模块、优盘存储模块等,能够完成GPS数据的接收、实时处理及...
