- Intelligent robotic navigation requires precise positioning information. The Global Navigation Satellite System (GNSS) enables such navigation by providing precise timing, velocity and positioning information to any adequately equipped receiver world-wide. A core capability of these receivers is to identify all visible satellites from a snapshot of received signal. This identification process, called signal acquisition, must be performed in shortest possible time in practical solutions. Conventionally search for the desired satellite in a serial fashion which involves large number of computations. Recently Fourier transform based methods were proposed to speed up the processing. However such a solution requires complex domain signal processing. We propose a partial-code serial search algorithm that significantly reduces the computational time with same reliability of acquisition results. ©2009 IEEE.
