THE DESIGN OF C/A CODE GLONASS RECEIVER

Hui, Liu, Leelung, Cheng, Qishan, Zhang 10 1900 (has links)
International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / GLONASS is similar to GPS in many aspects such as system configuration, navigation mechanism, signal structure, etc.. There exists the possibility of receiving and processing GLONASS signals with GPS technology. The frequency plan of the GLONASS system is different from that of GPS. This makes the front-end of GLONASS receiver more complicated. The work here manifests our initial effort in GLONASS receiving. A design scheme is proposed of a C/A code GLONASS receiver.

STUDY ON HARDWARE REALIZATION OF GPS SIGNAL FAST ACQUISITION

Lei, Huang, Yanhong, Kou, Qishan, Zhang 10 1900 (has links)
ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada / In GPS receiver the acquisition process generates two important parameters: the initial carrier frequency and the initial phase of the C/A code. In this paper two different methods for acquisition are mainly discussed: serial search in the time domain and FFT search in the frequency domain. Frequency domain acquisition involves using the Fast Fourier Transform (FFT) to convert the GPS signals into the frequency domain. One fast and easy-to-implement algorithm for averaging correlation is implemented and explained in detail. The FFT search method is both simulated in Matlab and evaluated in Altera Stratix DSP development board.

Behavioral VHDL Implementation of Coherent Digital GPS Signal Receiver

Daita, Viswanath 01 November 2004 (has links)
Global Positioning System is a technology which is gaining acceptance. Originally developed for military purposes, it is being used in civilian applications such as navigation, emergency services, etc. A system-on-chip application merges different functions and applications on a single substrate. This project models a GPS receiver for a system on chip application. The GPS receiver, developed as a core, is intended to be a part of a navigation tour guide being developed. The scope of this work is the GPS C/A code on the L1 carrier. The digital signal processing back-end in a GPS receiver is modelled in this work. VHDL modeling of various communiation sub-blocks, detection and demodulation schemes is done. A coherent demodulation of the GPS signals is implemented. GPS receiver calculates the position based on the data collected from four satellites. Given four satellites, acquisition of the data from the signals is performed and data demodulated from the same. Synthetic data is generated for validation purposes. Code acuqisition and tracking of the GPS C/A signal is implemented. Cadence NC-Launch VHDL simulator is used to validated the behavioral VHDL model.

Emulátor signálu navigačního systému GPS / Global Positioning System Signal Emulator

Hofman, Jan January 2012 (has links)
Thesis is adressed to the principals of a satellite navigation. It is focused on a determination of a longitude, latitude and altitude of a single point on the surface of the Earth. It contains analysis of navigation messages and a manner of processing of navigation signals in GPS receivers. Realization of an emulator of the navigation signal of GPS system in Matlab is also described. The purpose of this emulator is a generation of navigation messages, which could be transmitted by universal software radio. The last part of thesis contains the analysis of these signals, which were captured by second software radio.
