Multipaths (MP) are still one of the major error sources inGlobal Navigation Satellite Systems operating inchallenging environments such as urban areas. This paperpresents how diversity algorithms may improve themultipath mitigation performances. The diversity caneither lie on the space domain (antenna diversity) or onthe frequency domain (frequency band diversity). In bothcases, the algorithms principle consists in taking benefitfrom information redundancy given by multiple diversechannels.
