20150123843 | RECEIVER DUAL-REFLECTOR ANTENNA SYSTEM FOR INTERFERENCE SUPPRESSION ONBOARD SATELLITE - A system for interference suppression onboard a satellite may include an antenna that is configured to receive uplink signals from a ground-coverage area and to generate a first signal. A spot-beam antenna may be configured to receive interference signals and to generate a second signal. A processor may be configured to receive the first signal from the antenna and the second signal from the spot-beam antenna and to perform a cross-correlation to generate a composite signal that includes a null at an interference frequency. The antenna may be a shaped reflector antenna and the spot-beam antenna may be a parabolic reflector antenna. | 05-07-2015 |
20150130661 | GPS LOCATION SYSTEM USING MODAL ANTENNA - A modal antenna is implemented to provide a variable radiation pattern for improved global positioning system (GPS) signal reception. A multitude of antenna radiation patterns generated from a modal antenna provide the capability to optimally acquire GPS signals across a wide range of angles of arrival. Minimum radiation pattern roll-off is observed from the composite pattern generated from the multiple patterns. An algorithm is described that reduces the acquisition time for a location fix for cold and hot start conditions. | 05-14-2015 |
20150349417 | ANTENNA POSITIONING SYSTEM WITH AUTOMATED SKEWED POSITIONING - A method of receiving a satellite signal using a satellite dish connected to a receiver, the method includes a peak identification stage including automatically sweeping the satellite dish to identify peaks of satellite signals received by the receiver having a center frequency matching the center frequency of the satellite signal, a peak evaluation stage including automatically evaluating one or more said peaks by determining the bandwidth thereof and choosing the peak having a bandwidth matching the bandwidth of the satellite signal, and a signal strength maximizing stage including automatically sweeping the satellite dish until the signal strength of a satellite signal having said bandwidth is maximized. | 12-03-2015 |
20150355312 | METHOD AND SYSTEM FOR ESTIMATING THE DIRECTION OF ARRIVAL OF A TARGET SIGNAL RELATIVE TO A SATELLITE - A method and system for estimating a direction of arrival of a target signal relative to a measuring antenna array of an earth-orbiting satellite. The direction of arrival of the target signal being estimated on the basis of measurement signals corresponding to the target signal received respectively by at least a first measuring antenna and a second measuring antenna of the measuring antenna array. Each of the measurement signals are combined with a reference signal corresponding to the target signal received by a receiving antenna of the satellite. The receiving antenna has a maximum gain greater than the respective maximum gains of the first measuring antenna and of the second measuring antenna. The direction of arrival of the target signal is estimated from the signals obtained by combining the measurement signals with the reference signal. | 12-10-2015 |

20220137235 | METHODS OF AND SYSTEMS, NETWORKS AND DEVICES FOR REMOTELY DETECTING AND MONITORING THE DISPLACEMENT, DEFLECTION AND/OR DISTORTION OF STATIONARY AND MOBILE SYSTEMS USING GNSS-BASED TECHNOLOGIES - A system network and methods supported by a constellation of GNSS satellites orbiting around the Earth, and deployed for precise remote monitoring of the spatial displacement, distortion and/or deformation of stationary and/or mobile systems, including buildings, bridges, and roadways. The methods involve (i) embodying multiple GNSS rovers within the boundary of the stationary and/or mobile system being monitored by the GNSS system network, (ii) receiving GNSS signals transmitted from GNSS satellites orbiting the Earth, and (iii) determining the geo-location and time-stamp of each GNSS rover while the stationary and/or mobile system is being monitored for spatial displacement, distortion and/or deformation, using GNSS-based rover data processing methods practiced aboard the system, or remotely within the application and database servers of the data center of the GNSS system network. The GNSS rovers also include on-board instrumentation for sensing and measuring the depth of water ponding about the GNSS rovers. | 05-05-2022 |
