    摘要: A communication unit and a method for calibrating the alignment of a communication unit in a mobile carrier platform are described. The method incudes the following steps: determining an initial alignment of the communication unit with the moon on the basis of a position and bearing of the mobile carrier platform; moving the communication unit so that it adopts the initial alignment; tracing a search pattern with the communication unit starting from the initial alignment until a detection unit detects the moon; determining a real alignment of the communication unit when the detection unit detects the moon; determining a difference between the initial alignment and the real alignment of the communication unit; using this difference when performing a target alignment with the communication unit.

    摘要: A radio-frequency assembly is described which can be used in communication satellites, for example. The radio-frequency assembly contains a signal source in the form of a semiconductor amplifier output, an impedance matching filter, and a radio-frequency waveguide. The impedance matching filter is connected to the semiconductor amplifier output on the input side and to the radio-frequency waveguide on the output side. The impedance matching filter has a different impedance value on the input side from that on the output side and is matched to the semiconductor amplifier output on the input side and matched to the radio-frequency waveguide on the output side. Consequently, a separate matching circuit between semiconductor amplifier output and radio-frequency waveguide is no longer necessary.

    摘要: A waveguide arrangement contains a first ridged waveguide and a second waveguide. The first ridged waveguide contains a first casing with a first cavity and a first ridge extending in the first cavity in the longitudinal direction. The first ridge is conductively connected to a wall of the first casing. The second waveguide contains a second casing with a second cavity. The first ridged waveguide overlaps the second waveguide in the longitudinal direction of the waveguide arrangement in a connecting section to produce a capacitive coupling between the first ridge and the second waveguide.

    摘要: A high-frequency module can be used in communication satellites. The high-frequency module contains an electronic unit and a housing. The housing at least partially encloses the electronic unit, and the electronic unit is arranged at least partially in an interior space of the housing. An internal connector is arranged on the housing, which is coupled to the electronic unit such that electrical signals can be transmitted between the electronic unit and the internal connector. The internal connector is constructed integrally with at least a part of the housing. This allows a thermo-mechanical stress on the electronic unit to be reduced.

    摘要: A controller arrangement includes a controller, an actuator, and a measuring element. The measuring element captures a control variable with a predetermined sampling rate in consecutive sampling cycles and transmits it to the controller. The controller compares the control variable with a predetermined reference variable and determines how the control variable differs from the reference variable. The controller, in a first cycle, starts with a predetermined regulating variable and outputs it to the actuator, and subsequently determines how the control variable differs from the reference variable; in a second cycle, the controller varies the regulating variable based on the difference of the control variable from the reference variable in the first cycle, and outputs it to the actuator, and subsequently determines how the control variable differs from the reference variable; in a third cycle, the controller varies the regulating variable and outputs it to the actuator.

    摘要: A method for adjusting a radiation direction of an optical communication signal between a communication platform and a remote station includes: starting from an initial position of a beam deflection unit of the platform for steering the optical communication signal, adopting deflection positions of the beam deflection unit along two different lines of movement and in opposite directions along the lines of movement, the deflection positions being consistent with deflection angles having the same absolute value, each deflection position being held for a different period; measuring an intensity of the signal at the station; when an intensity change in the signal is discovered at the station, ascertaining a signal quality change in the signal and recording the duration of this intensity change; determining that intensity change that pertains to the best signal quality change, and the associated duration; changing the intensity of a guidance beam for the duration previously determined.

    摘要: The disclosure relates to a method for operating a selective switching device for signals, a related selective switching device, and a message transmission system having the selective switching device. An embodiment of the method includes the following steps, not necessarily in this order: determining a current temperature in the region of the selective switching device; determining a signal shift of the selective switching device due to the current temperature; adding the signal shift to an input signal of the selective switching device as to receive a compensated signal for which the signal shift due to the current temperature is compensated; and removing the signal shift from an output signal of the selective switching device as to receive a corrected signal for which the compensation is corrected.
