摘要： A rotation determiner (23) determines whether the azimuth (AZ) angle of an antenna (3) rotates beyond a rotation range within a predetermined duration of time on the basis of a predicted orbit value. When the AZ angle of the antenna (3) is determined to rotate beyond the rotation range, an orbit determiner (24) determines whether an estimated satellite position is within a drivable range in which the AZ angle rotates from a reference value beyond the rotation range, and in which an xEL axis can be driven in a state in which the AZ angle is set to a predetermined value that is permissible for the AZ angle. When the AZ angle rotates beyond the rotation range and while the estimated satellite position is within the drivable range, a determiner (22) sends a command to a switching section (17) to cause three-axis control, and a command to cause an AZ command operator (15) to output a command value that keeps the AZ angle at a predetermined value. When the AZ angle rotates beyond the rotation range and while the estimated satellite position is not within the drivable range, or when the AZ angle does not rotate beyond the rotation range, the determiner (22) sends a command to the switching section (17) to cause two-axis control.

摘要： Systems for maintain pointing of a phased array antenna in a direction maximizes to an extent possible the effective antenna gain is provided. The system includes a gyroscope and a Kalman Filter. The Kalman filter estimates an antenna pointing direction for each successive time step based on gyroscope readings and based on the results of a local search for maximum gain performed in the neighborhood of a previous antenna pointing direction.

摘要： A system and technique for improving the speed and ease of missing vehicle location and recovery by vehicle-carried transponder periodic coded replies to radio interrogation by a network of (VHF) transmitting towers, by integrating a concealed GPS location receiver with the transponder and providing the GPS-obtained coordinate information through the VHF network to enable a preliminary initial recovery location from which to home-in for recovery by subsequent direction-finding from the periodic transponder responses. Other location-on-demand services are also readily operable through the use of this VHF network, including providing said GPS coordinate or location information on the Internet.

摘要： An improved satellite tracking antenna system mounted to a moving object and a method for operating the same detect and track elevation and azimuth angles of a satellite using only two gyro sensors in a two-axis satellite tracking antenna system, and detect and track an azimuth angle of the satellite using only one gyro sensor in a one-axis satellite tracking antenna system. The antenna system detects the satellite position using two gyro sensors, which are mounted to be orthogonal to each other to a planar axis perpendicular to a satellite-directed target point of the antenna, and continuously tracks the satellite position using a calibration algorithm without using additional absolute angle sensors, resulting in simplified system configuration and reduced production costs.

摘要： A phased array spread-spectrum system maximizes signal strength of a spread-spectrum signal with multipath. RF/IF section (21) receives a plurality of spread-spectrum signals. RF/IF section (22) receives a plurality of phased versions of the plurality of spread-spectrum signals. Digital delay devices (27, 28) delay the received spread-spectrum signals with respect to their phased versions by a plurality of delays. Summers (29, 30) combine the delayed spread-spectrum signals and their phased versions as a plurality of combined signals. Despreader (31) despreads the combined signals as a plurality of despread signals. Magnitude device (32) generates a plurality of magnitude values from the despread signals. Shift register (33) stores a plurality of previous-magnitude values and present-magnitude values previously and presently generated by the magnitude device (32). Comparator (34) compares the previous-magnitude values to the present-magnitude values and outputs a plurality of comparison signals. Digital delay devices (27, 28), responsive to the comparison signals, lengthen or shorten the plurality of delays.

摘要： A satellite tracking antenna system comprises three or four plane antennas juxtaposed on a single plane. A first and a second antenna are juxtaposed in an azimuth direction, and a phase difference between signals received by these antennas is detected in order to determine a declination of an antenna unit with respect to the satellite as viewed in the azimuth direction. The first and a third antenna are juxtaposed in an elevation direction, and a phase difference between signals received by these antennas is detected to determine a declination of the antenna unit with respect to the satellite as viewed in the elevation direction. The antenna unit is driven so as to reduce these declinations to zero. Stated differently, values of a sine and a cosine function are extracted which have a phase difference between signals received by a pair of antennas as a parameter, and a tangent value representing the ratio therebetween is calculated and is then inversely converted to provide phase difference information.

摘要： In a satellite tracking control system, a receiver derirves a pair of elevation (EL) and cross-elevation (XEL) tracking error signals having a quadratic relationship in a coordinate system from a signal received from a polar-orbital satellite. Elevation and cross-elevation motors are respectively controlled in response to the elevation (EL) and cross-elevation (XEL) tracking error signals. An azimuth controller derives an azimuth control signal from angle data representing the angles of the antenna about the azimuth, elevation and cross-elevation axes detected by angle detectors. Preferably, the antenna is rotatable about the elevation (EL) axis in the range between zero and l80 degrees.
