Separately, these demands can be fulfilled by multi-antenna systems using spatial filtering and carrier-phase positioning algorithms like real-time kinematic (RTK), respectively. However, combining these approaches encounters a severe issue: The spatial filtering induces a phase offset into the measured carrier phase leading to a loss of position accuracy. This paper presents a new approach to compensate for the phase offset in a blind manner, (i.e., without knowing the antenna array radiation pattern or the direction of arrival of the signals). The proposed approach is experimentally validated in two jamming scenarios. One includes a jammer with increasing power and the other includes a moving jammer. The results demonstrate that the approach successfully compensates for the phase offset and, hence, allows for the combined use of RTK positioning and spatial filtering even under jamming.

They now represent a vital part of the modern information infrastructure and are entering everyday life. This fantastic growth has been made possible by GNSS (Global Navigation Satellite System). These systems are widely used, not only in professional applications but also, by enabling personal navigation (e.g. car navigation or hand-held GPS navigators), in the mass market. Futhermore, a number of key communication technologies like GSM (Global System for Mobile Communications) mobile networks rely on timing information provided by GNSS. At present there two GNSS : the US Global Positioning Sytem (GPS) and the Russian GLONASS (GLObal NAvigation Satellite System).
