Block Acquisition of Weak GPS Signals in a Software Receiver
Block algorithms have been developed to acquire very weak Global Positioning System (GPS) coarse/acquisition (C/A) signals in a software receiver. These algorithms are being developed in order to enable the use of weak GPS signals in applications such as geostationary orbit determination. The algorithms average signals over multiple GPS data bits after a squaring operation that removes the bits...
متن کاملSignal Search and Acquisition Algorithms for Software GPS Receiver
Based on the software platform of MATLAB simula-tion, the paper collects the real GPS intermediate frequency (IF) signal by the IF signal sampler, and uses it to carry out the time-domain correlation acquisition and the fast Fourier transform (FFT) acquisition on the C/A code of GPS signal, and also carry out the decision of the singlebinary search and the M/N search on the personal computer. T...
متن کاملSoftware Receiver Strategies for the Acquisition and Re-Acquisition of Weak GPS Signals
The acquisition of weak GPS signals is a challenging problem. The lack of a priori information regarding the signal parameters typically necessitates a search through an uncertainty space in order to find the signal of interest. To acquire weak signals requires longer observation intervals to accumulate sufficient energy from the signal of interest. Perversely, a direct increase in the observat...
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 کاملCompensation of Doppler Effect in Direct Acquisition of Global Positioning System using Segmented Zero Padding
Because of the very high chip rate of global positioning system (GPS), P-code acquisition at GPS receiver will be challenging. A variety of methods for increasing the probability of detection and reducing the average time of acquisition have been provided, among which the method of Zero Padding (ZP) is the most essential and the most widely used. The method using the Fast Fourier Transform (FFT...
