Abstract: Embodiments provide a first apparatus, comprising: a GNSS receiver configured to receive GNSS signals, a mobile communication transceiver configured to operate in a mobile communication network, wherein the first apparatus is configured to determine at least one parameter based on the received GNSS signals or use at least one parameter determined by a second or third apparatus based on GNSS measurements, wherein the first apparatus is configured to receive with the mobile communication transceiver an information message from a second apparatus or a third apparatus of the mobile communication network, the information message comprising an integrity information describing an integrity status of the GNSS signals, wherein the first apparatus is configured to at least one out of determine the at least one parameter in dependence on the integrity information, report the at least one parameter taking into account the integrity information, take a specific action in dependence on the integrity information.

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.
