ABSTRACT:
Systems and methods for acquiring global navigation satellite system (GNSS) signals. An incoming signal is multiplied with a time shifted spreading code replica and converted to zero (or very low) nominal frequency. The converted signal is filtered and downsampled by a large scale. A signal power metric and frequency offset are then determined. This is performed over multiple slices. Fast acquisition is achieved by parallel concatenation of numerous slices.
