This paper describes an approach of implementing software based GPS receiver acquisition and tracking for L1 C/A signal on ADSP SHARC. The main objective of this paper is bring out fast GPS signal tracking method using which more number of ch

BlueCore7 is a single-chip radio and baseband IC range for Bluetooth 2.4GHz systems including enhanced data rates (EDR) to 3Mbits/s. It includes an integrated FM transmitter and receiver with stereo audio input and output stages, Bluetooth low en

在GPS软件接收机和SINS辅助GPS跟踪技术的基础上,提出了一种SINS/GPS超紧致组合导航方案。该超紧致方案在GPS软件接收机的捕获环节中加入了基于相位估计的精细捕获算法,从而提高了频率捕获精度,省略了频率跟踪牵引过程 在信号跟踪环节中,利用SINS位置、速度信息与卫星参数,求取接收机与卫星之间的径向距离和径向距离率,为码环、载波环提供辅助,从而降低了载体动态变化对跟踪环的影响,提高了跟踪环的动态跟踪性能 同时,降低载波环噪声带宽,减小码环相关间隔,从而提高了载波环和码环的跟踪精度。-On
