Abstract: A wireless antenna system for a terminal comprises an antenna structure and frontend ports for connecting to transmit and/or receive circuitry of the terminal. The antenna system is operable in a first radiation mode and a second radiation mode, wherein the modes are orthogonal. The circuitry is arranged to map the first feed port to the antenna structure for the first radiation mode across a first frequency band having a bandwidth which covers one of an uplink frequency band and a downlink frequency band of the transmit/receive circuitry. The circuitry is arranged to map the second feed port to the antenna structure for the second radiation mode across a second frequency band, wherein the second frequency band covers both of an uplink frequency band of the transmit/receive circuitry and a downlink frequency band of the transmit/receive circuitry. The above concepts are extendible to more than two modes.

Abstract: A method for characterizing Coriolis gyros, in the case of which the interaction of the system comprising force transmitters, a mechanical resonator and excitation/readout vibration pick-offs is represented as a discretized, coupled system of differential equations. The variables of the system of equations represent the force signals supplied by the force transmitters to the mechanical resonator and the readout signals produced by the excitation/readout vibration pick-offs. The coefficients of the system of equations contain information relating to the linear transformation which maps the force signals onto the readout signals. The coefficients are determined by measuring force signal values and readout signal values at different instants and substituting them into the system of equations.

Abstract: In a method for electronic tuning of the frequency of the read oscillation to the frequency of the stimulation oscillation in a Coriolis gyro, the resonator of the Coriolis gyro has a disturbance force applied to it such that the stimulation oscillation remains essentially uninfluenced. The read oscillation is changed so that a read signal that represents the read oscillation contains a corresponding disturbance component. The frequency of the read oscillation is controlled so that the magnitude of the disturbance component contained in the read signal is a minimum.

Appropriate disturbance forces are applied to the resonator of the Coriolis gyro such that at least one natural oscillation of the resonator is stimulated that differs from the stimulating and read oscillations. A change in a read signal which represents the read oscillation and results from the stimulation of the at least one natural oscillation is determined as a measure of the zero error.

Abstract: A method for compensation of the zero error of a Coriolis gyro. The frequency of the read oscillation is modulated. The output signal from a rotation rate control loop or quadrature control loop for the Coriolis gyro is demodulated in synchronism with the modulation of the frequency of the read oscillation to obtain an auxiliary signal. The auxiliary signal is a measure of the zero error. A compensation signal is produced and passed to the input of the rotation rate control loop or quadrature control loop, with the compensation signal being controlled such that the magnitude of the auxiliary signal is as small as possible.
