摘要： An antenna array is steered electronically by controlling the transmission speed of the RF signal in feed line of each radiator in the array. The transmission speed is controlled using phase shifters, that include variable dielectric constant (VDC) material causing the change in transmission speed. The control signal applied to the VDC material generates the required phase shift. The control signal is calculated for each phase shifter in real time for each control cycle, so as to enable the main beam to track a target, such as a satellite. The control signal is a square wave signal, and each control signal has a specifically calculated duty cycle or frequency to generate the required phase shift.

摘要： L'invention concerne un dispositif (400) de localisation d'un objet mobile susceptible de subir une dynamique de rotation sur lui-même. Le dispositif comporte un récepteur (410) d'un système de positionnement par satellites, une centrale inertielle (420), et un module hybride de navigation (430). Le module hybride de navigation (430) est configuré pour modéliser d'une part le mouvement d'une antenne (54) du récepteur (410), et d'autre part le mouvement d'un satellite, afin d'estimer une valeur représentative de l'effet Doppler subi par le signal émis par le satellite et reçu par l'antenne. Cette valeur est communiquée à un module d'acquisition (411) du récepteur afin de faciliter une ré-acquisition du signal du satellite suite à une perte du signal provoquée par le mouvement de rotation de l'objet mobile. Le mouvement de l'antenne (54) est notamment estimé grâce à la connaissance de la distance séparant l'antenne d'un centre d'inertie de l'objet mobile.

摘要： A positioning device (4) is disclosed comprising at least one antenna (14, 16) for receiving ranging signals, such as GNSS signals. The device comprises a local oscillator (18) for providing a local frequency or phase reference and an inertial sensor (22) for measuring a movement of the device. A processor (36) is provided for performing calculations. The device can receive a first reference signal at a known or predictable frequency or phase. A local oscillator offset determination module (26) is provided to calculate an offset to the received frequency or the received phase based on the movement of the receiver in the direction of the first reference source. A local signal generator (28) can then use the local frequency or phase reference from the local oscillator (18), and the offset calculated by the local oscillator offset determination module (26), to provide a local signal using a local signal generator (28). The local signal can be correlated against a received ranging signal for use in positioning calculations performed by a positioning calculator (34).

摘要： A mobile station determines an approximate latitude using a measured feature of the Earth's magnetic field. An approximate longitude may also be determined. The mobile station uses the approximate latitude and longitude, if determined, to assist in determining a position fix for the mobile station, e.g., by determining a list of visible satellites in a satellite positioning system (SPS) during search and acquisition of satellite signals and/or using the approximate position as a seed position in the position computation. The feature of the Earth's magnetic field may be, e.g., inclination or vertical intensity, and may be determined using data from a three-dimensional magnetometer and a three-dimensional accelerometer. An instantaneous value of the magnetic field feature may be averaged to reduce the affects of motion and the presences of large metallic masses.
