Abstract:	A novel proposal is made for the accurate determination of position and antenna attitude of a multi-antenna GNSS receiver even in a multipath environment. In contrast to previous work no calibration of the antenna array, of mutual coupling nor of the antenna channel mismatches are necessary. This allows for the usage of heavily miniaturized antenna arrays and RF-Frontends with significant mutual coupling as well as highly integrated systems with non-negligible crosstalks and tolerances. The novel algorithms treats the estimation of antenna attitude, the multipath detection and mitigation as well as the calibration as a coupled problem and estimates the relevant unknowns in a joint procedure. Due to this approach a reliable position estimate can be determined even in challenging conditions without the need for very accurately calibrated - or nearly ideal hardware components.
