DOI: 10.1007/s12555-016-0705-3
Abstract: To receive GPS satellite signals continuously on a spinning vehicle, an omnidirectional wraparound antenna or multiple patch antennas are needed. If multiple patch antennas are used, as spin effects, Doppler frequency is induced by the… read more here.

DOI: 10.1049/el.2018.0984
Abstract: Due to its flexibility in calculating frequency spectrum, the chirp z-transform (CZT) has been used in various applications where high-frequency resolution is desirable, e.g. the acquisition of global positioning system (GPS) signals. However, the CZT… read more here.
