    摘要: A method for operating a rocket propulsion system comprises the steps of supplying oxygen to a combustion chamber, supplying hydrogen to the combustion chamber and combusting the oxygen-hydrogen mixture in the combustion chamber. The rocket propulsion system is operated alternately in a first operating mode, in which oxygen and hydrogen are supplied to the combustion chamber in a first mass mixing ratio of oxygen to hydrogen, and in a second operating mode, in which oxygen and hydrogen are supplied to the combustion chamber in a second mass mixing ratio of oxygen to hydrogen that is greater than the first mass mixing ratio.

    摘要: A wireless communication unit for compensating for Ionospheric group delay in a satellite communication system. The wireless communication unit comprises: a receiver configured to receive a multi-carrier signal from a satellite; and a processor coupled to the receiver. The processor is configured to: process the multi-carrier signal to produce a plurality of digital representations of individual carriers of the multi-carrier signal; estimate, from the plurality of digital representations of individual carriers of the multi-carrier signal, a Total Electron Content, TEC, value associated with a communication path between the satellite and the wireless communication unit through Earth's Ionosphere; and apply compensation for Ionospheric group delay subjected to the multi-carrier signal based on the determined TEC value.

    摘要: An ion sensor comprises an electron repelling electrode to be placed at a negative electric potential, and an ion repelling electrode to be placed at a variable positive electric potential. The electron repelling electrode is formed by a diaphragm element having a diaphragm opening for the passage of an ion beam. The ion repelling electrode forms a blind hole which faces the diaphragm opening with its open hole end and the hole surface of which forms a collector face for detecting impinging ions. With such an ion sensor it is possible, for example, to test the energy spectrum of the ions contained in an exhaust plasma plume of an ion thruster.

    摘要: An apparatus comprising a blanker configured to provide a plurality of blanked signals, each blanked signal corresponding to a respective correlator channel signal of a plurality of correlator channel signals. The correlator channel signal is obtainable based on the respective blanked signal and a respective signal replica of a plurality of signal replicas, the signal replicas being shifted with respect to each other. The blanker is configured to obtain each blanked signal based on applying a respective thresholding scheme to a respective signal component of a plurality of signal components derived from a received spread-spectrum signal. The respective thresholding scheme is based on the respective signal component and the signal replica based on which the correlator channel signal corresponding to the respective blanked signal is obtainable. A receiver comprising such an apparatus is provided as is a method comprising providing a plurality of blanked signals.

    摘要: A signal coupling device associating a first frequency band signal and a second, different frequency band, signal in a common waveguide and distributing the signals to two separate waveguides. The device comprises first and second circular waveguides. The second waveguide is coaxially arranged inside a cylindrical interior of the first waveguide. The first waveguide comprises inwardly projecting inner circumference projections in a region occupied only by the first waveguide. The projections activate higher modes from a fundamental mode. The first and second waveguides and the projections cause the superposition of the fundamental and higher modes to produce a wave front having field components in the first frequency band only in a cylindrical ring region between the second waveguide outer circumference and the first waveguide inner circumference, and having field components in the second frequency band only in a cylindrical interior of the second waveguide.
