GPS Reflected Signal Analysis using Software Receiver
A reflected GPS signal is normally considered as noise (multipath). However, we believe that a reflected signal contains information about the reflecting object. Though, this information may not be useful for accurate position computation, it may help us to identify the reflecting object itself, which is a type of remote sensing. Besides, by measuring the time delay of the reflected signal, it ...
متن کاملSmoother-Based GPS Signal Tracking in a Software Receiver
Global Positioning System (GPS) signal tracking algorithms have been developed using the concepts of Kalman filtering and smoothing. The goal is to improve phase estimation accuracy for non-real-time applications. A bit-grabber/software-receiver has been developed for the GPS L1 coarse/acquisition signal. The bit grabber down-converts, digitizes, and stores the raw RF signal. The software recei...

متن کاملGPS Signal Acquisition and Tracking An Approach towards Development of Software-based GPS Receiver
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 ve...
متن کاملBandwidth Optimization of Carrier/Code Tracking Loops in GPS Receiver
Global Navigation Satellite System (GNSS) is the standard generic term for satellite navigation systems that provide autonomous geospatial positioning with global coverage. As of 2007, the United States NAVSTAR Global Positioning System (GPS) is the only fully operational GNSS. Based on bandwidth optimization criterion, the GPS receiver is proposed for solving the carrier/code phase tracking pr...
