Abstract: Error and integrity evaluation during a position determination, includes: recording position values (P?N, P?2, P?1) and calculating clock errors of a receiver via time-discrete runtime measurements by a satellite navigation system; recording a first pseudo-distance at a later time via time-discrete runtime measurement by the satellite navigation system; extrapolating a position value (P?0) of the receiver at the later time and extrapolating a clock error of the receiver at the later time; establishing a distance (r?0) between the extrapolated position value (P?0) of the receiver and the position of a satellite (S0) of the satellite navigation system at the later time, wherein a quality measure for the usability of the position determination with the satellite is obtained by forming a second pseudo-distance based on the sum of the established distance (r?0) and the extrapolated clock error at the later time and comparing the second pseudo-distance with the first pseudo-distance.

Abstract: Micromachined vibratory gyroscope having two or more coplanar movable masses suspended over a planar substrate. Two perpendicular axes (x and y) are defined within the substrate plane, while a third, the z-axis or input axis, is defined to be perpendicular to the substrate plane. The movements of the two masses along the x-axis are coupled through an electrostatic coupling means so that the natural resonant frequency of the in-phase mode and that of the anti-phase mode are separated from each other for the resonances along the x-axis. When the two masses are driven to vibrate along the x-axis in the anti-phase mode and the device experiences rotation about the z-axis, Coriolis forces act differentially on the masses in the Y-direction, causing the two masses to dither in an anti-phase motion along the y-axis. The anti-phase dithering along the y-axis can be sensed directly by a rate sensor to measure the rate of rotation about the z-axis.
