Abstract: A novel proposal is made for accurate determination of position and antenna attitude of a multi-antenna GNSS receiver even in jammed and spoofed environment. In contrast to previous work no calibration of the antenna array, of mutual coupling nor of the antenna channel mismatches and crosstalks is necessary. This allows for the usage of heavily miniaturized antenna arrays with significant mutual coupling as well as highly integrated systems with non-negligible crosstalks and tolerances. The novel algorithm treats the estimation of antenna attitude, the spoofing and jamming 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.
