Multipaths (MP) are still one of the major error sources in Global Navigation Satellite Systems operating in challenging environments such as urban areas. This paper presents how diversity algorithms may improve the multipath mitigation performances. The diversity can either lie on the space domain (antenna diversity) or on the frequency domain (frequency band diversity). In both cases, the algorithms principle consists in taking benefit from information redundancy given by multiple diverse channels.
