Satellite Signal Acquisition, Tracking, and Data Demodulation
In practice, a GPS receiver must first replicate the PRN code that is transmitted by the SV being acquired by the receiver; then it must shift the phase of the replica code until it correlates with the SV PRN code. When cross-correlating the transmitted PRN code with a replica code, the same correlation properties occur that occurs for the mathematical autocorrelation process for a given PRN co...
متن کاملSignal Acquisition and Tracking Loop Design for GNSS Receivers
where • Ai is the amplitude of the i th useful signal; • τi is the code phase delay introduced by the transmission channel; • ci(t − τi) is the spreading sequence which is given by the product of several terms and it is assumed to take value in the set {−1, 1}; • di(t − τi) is the navigation message, Binary Phase Shift Keying (BPSK) modulated, containing satellite data, each binary unit is call...
متن کاملImplementation of Gps Signal Acquisition and Tracking in Fpga
GPS Receivers are used for both military and civilian applications. This paper presents the GPS Receiver for System on Chip (SoC) application. In this paper the GPS Receiver is been implemented as System on Chip in FPGA board. VHDL modeling for the back end of GPS Receiver is designed. As baseband signal processing is the main aspect in the GPS receiver, it is achieved by this software GPS Rece...
متن کاملSignal Acquisition
A new pseudo asynchronous level crossing analogueto-digital converter (ADC) architecture targeted for low-power, implantable, long-term biomedical sensing applications is presented. In contrast to most of the existing asynchronous level crossing ADC designs, the proposed design has no digital-toanalogue converter (DAC) and no continuous time comparators. Instead, the proposed architecture uses ...
متن کاملIRNSS Orbit Determination and Broadcast Ephemeris Assessment
The Indian Regional Navigation Satellite System (IRNSS) is an emerging satellite based navigation system offering an independent positioning and timing service over India and neighboring regions. Based on satellite laser ranging data collected by selected stations of the International Laser Ranging Service (ILRS) precise orbits have been determined for the first pair of inclined geosynchronous ...
