Abstract: GPS signal diffractions caused by objects such as building structures surrounding a GPS antenna can introduce significant errors in applications such as deformation monitoring. This paper presents an approach for modelling and mitigating errors caused by GPS signal diffractions by considering the fact that the geometry relating the GPS satellites, the antenna and objects that diffract GPS signals does not change significantly between sidereal days. Test results show that the proposed method is effective and can significantly reduce GPS diffraction errors.
