GPS Signal Acquisition and Tracking An Approach towards Development of Software-based GPS Receiver

  title={GPS Signal Acquisition and Tracking An Approach towards Development of Software-based GPS Receiver},
  author={Dinesh Raj Manandhar and Yong Tat Sum and Ryosuke Shibasaki},
Software-based GPS (SGR) Receiver helps us processing the GPS signal at the lowest level of GPS raw signal data from the antenna. A software-based GPS receiver consists of a front-end device that converts the radio frequency signal from the antenna to an intermediate frequency in digital format. The signal thus converted is processed by high level programming language to compute position and velocity. In SGR, it is possible to do acquisition and tracking using different parameters and threshold… Expand
