摘要： A GNSS receiver including a processing unit adapted to process radio signals transmitted from an active set of signal sources and based thereon produce position/time related data. The signals of the active set are processed in parallel with respect to a real-time signal data rate of the signals by a respective tracking channel resource allocated for each signal source. The processing unit also has a monitoring channel resource adapted to process radio signals transmitted from each of at least two signal sources in an additional set of signal sources different from the signal sources in the active set. The processing unit is adapted to process the radio signals of the additional set according to a cyclic processing sequence such that the signals from any of the signal sources in the additional set can be included into a navigation solution without delay.

摘要： The present invention relates to reception and processing of spread spectrum signals to produce position/time related data. A proposed receiver includes a radio signal processing unit, which is at least partly implemented in software running on a microprocessor. The processor is also adapted to effect at least one separate software-controlled function. The receiver is adapted to operate the radio signal processing unit on at least two processing intensity levels each with different processing times. Thereby, when the radio signal processing unit operates on a low processing intensity level, a first amount of processing capacity is available for the at least one separate software-controlled function; and when the radio processing unit operates on a high processing intensity level, a second amount of processing capacity is available for the at least one separate software-controlled function. When the processor's over-all processing capacity is constant, the second amount is smaller than the first amount.

摘要： The present invention relates to processing of spread spectrum signals, where a continuous signal of a comparatively high frequency is received. This signal is sampled at a basic sampling rate whereby a resulting sequence of time discrete signal samples is produced, which are in turn quantized into a corresponding level-discrete sample value. A plurality of data words are formed, which each includes one or more consecutive sample values. Information obtained from these data words is correlated with at least one representation of a signal source specific code sequence, which has been pre-generated in the form of a code vector. The correlation step specifically involves correlating at least each vector in a sub-group of the code vectors with at least one vector that has been derived from the data word. Thereby resulting data is produced.
