The widespread use of global navigation satellite systems (GNSSs) in professional applications has posed very stringent requirements in terms of adoption and absolute performance. Unfortunately, current GNSS performance is not enough to fulfill the requirements of professional applications like farming, critical timing infrastructures or autonomous driving. In order to boost the adoption of these applications, the European GNSS agency (GSA) launched the FANTASTIC project aimed at enhance robustness and accuracy of GNSS in harsh environments. We will focus in this paper on the part related with the development of a weighting and exclusion function with a dual circularly polarized antenna. The idea is to reduce the effects of multipath by weighting and/or excluding those measurements affected by multipath. The capabilities of a dual polarized antenna to sense multipath will be exploited to define an exclusion threshold and to provide the weights. Real-world experiments will be shown assessing the improvements of applying the developed technique in the positioning solution.
