    摘要: Various base station cellular enclosures are detailed herein. An airfoil enclosure housing may be present that defines a cavity for housing a base station cellular antenna. The housing may have a leading edge and a vent that permits air from external the airfoil enclosure housing to enter the cavity of the airfoil enclosure housing. The enclosure may further include a rotatable coupling that attaches the airfoil enclosure housing to a support structure. The rotatable coupling can allow the airfoil enclosure housing to rotate based on wind such that the leading edge faces into the wind.

    摘要: The present invention provides a reflective array surface. The reflective array surface includes a functional board that is configured to perform beam modulation on an incident electromagnetic wave and a reflection layer that is disposed on one side of the functional board and is configured to reflect an electromagnetic wave, where the functional board includes two or more functional board units and the reflection layer includes reflection units, where the number of reflection units corresponds to the number of functional board units, where the functional board unit and a reflection unit corresponding to the functional board constitute a phase-shifting unit that is used for phase shifting. According to the reflective array surface in the present invention, a functional board unit and a reflection unit corresponding to the functional board unit constitute a phase-shifting unit that is used for phase shifting, which can solve a problem in the prior art that a phase-shifting effect is not exquisite enough and a beam modulation capability for an electromagnetic wave is poor, thereby affecting bandwidth and working performance of a reflective array antenna. In addition, the present invention further provides a reflective array antenna.

    摘要: A vehicle-mounted satellite signal receiving system adopting a satellite tracking system combining gyro tracking and hybrid tracking is disclosed which can correct a sensitivity coefficient for correcting a gyro sensor output signal to make up for a sensitivity error, even when a drift is produced in the sensitivity error. In this system, gyro tracking is caused when the received power level is above a threshold power level. The gyro tracking is done by determining the angular velocity .omega. of an antenna as .omega.=-(.omega.G.times..DELTA.SB+.omega.G from a value obtained by inverting the sign of the product of a gyro tracking angular velocity .omega.G and a sensitivity coefficient .DELTA.SB for dealing with the sensitivity error and a predetermined offset error correction value .omega.G and setting the antenna to .omega.. When .DELTA.SB is inaccurate and a sensitivity error is generated in the gyro sensor output signal, the received power level is reduced. When the received power level becomes lower than a threshold power level LB, the sensitivity coefficient is corrected on the basis of the sense of the angular velocity .omega.S in the hybrid tracking (step tracking) and in the gyro tracking.

    摘要: An embodiment of the present invention is a system for automatically pointing a directional antenna. The system comprises two GPS antennas mounted at horizontally opposed extremities of the directional antenna, the placement is such that the GPS antennas lie on a line having a normal vector approximately parallel to a boresight of the directional antenna. The outputs from the GPS antennas are downconverted to a measurement frequency and differentially phase compared for each of a plurality of radio visible GPS satellites. A measurement controller that receives the phase comparisons. A navigation computer receives measurements from the measurement controller and uses a microprocessor to calculate the GPS latitude and longitude and the attitude angles of the pair of GPS antennas. A servo points the directional antenna at a particular target communications satellite, based on the computed azimuth, elevation, latitude, and longitude, as provided by the navigation computer. One of these servos is used to move the GPS antennas in roughly a circle to average out multipath effects to improve accuracy and to reduce integer ambiguities.
