Abstract: A method for determining a position of a receiver via use of encrypted signals of a public regulated service. The method comprises transmitting PRN code chips to the receiver by an assistance server. The method further comprises storing the transmitted PRN code chips to be used before a designated time interval by the receiver. The method further comprises receiving the encrypted signals during the designated time interval by the receiver from satellites in line-of-sight to the receiver. The method further comprises determining the position of the receiver via use of the encrypted signals and the stored PRN code chips by the receiver.

Abstract: Embodiments provide a satellite navigation receiver. The satellite navigation receiver has a receiver unit and a transmitter or a controller. The receiver unit is configured to receive and process a satellite navigation signal from a satellite navigation system at the certain time, to obtain a received signal, the received signal having a first component in a digital form, wherein the first component in the digital form is encrypted. The transmitter is configured to transmit the first component in the digital form together with an identification of a user of the satellite navigation receiver at the certain time. The controller is configured to store the first component in the digital form on a non-volatile storage medium in association with other data representing an information from a location, at which the satellite navigation receiver was located at the certain time.

Abstract: A pseudorange determinator for providing a pseudorange information representing an estimate of a distance between a transmitter and a receiver on the basis of a modulated signal having a sequence of symbols, wherein a primary code sequence is modulated in accordance with a secondary code sequence is configured to step-wisely correlate a portion of a received signal having at least two symbols with at least two reference sequences, a first reference sequence representing at least two subsequent symbols having same phases and a second reference sequence representing at least two subsequent symbols having different phases, to step-wisely acquire, in dependence on a result of the correlations, a portion of the secondary code sequence. The pseudorange determinator is configured to provide the pseudorange information on the basis of an acquisition of a meaningful portion of the secondary code sequence.

Abstract: A system for determining an actual interferer transmitting an interfering signal including first frequency portions of the interfering signal in a predetermined frequency band of a useful signal is provided. The system includes a signal evaluator configured to determine for each possible interferer of the plurality of possible interferers coefficient information of the possible interferer based on representation information of the possible interferer and based on processing information, such that the coefficient information of the possible interferer and the representation information of the possible interferer together indicate the preprocessed signal, wherein the processing information and the preprocessed signal together indicate the compressed signal.

Abstract: A multi-frequency band receiver includes first and second receive paths, a combiner, a code multiplex baseband stage and an amplifier controller. The first and second receive paths receive and process first and second code multiplex signals, respectively. The first or the second receive path includes an amplifier having a variable gain factor. The combiner superposes the first and second processed code multiplex signals. The code multiplex baseband stage processes the superposed code multiplex signal to obtain and use first and second baseband receive signals. The first and second baseband receive signals represent data of the first and second code multiplex signals, respectively. In addition, the amplifier controller controls the gain factor of the amplifier having a variable gain factor so that the first or the second baseband receive signal includes a minimum reception quality which can be variably predetermined and is dependent on the operating state.
