ABSTRACT:
A spread spectrum signal receiver includes a radio signal processing unit, which is at least partly implemented in software running on a processor. The processing unit is adapted to estimate a respective processing demand required to produce position/time related data based on each subset of a number of candidate subsets of signal sources among a group of potential signal sources. Each candidate subset contains at least a minimum number of signal sources, which is necessary to produce the position/time related data of a desired quality. The processing unit is adapted to select a set of preferred signal sources from the group of potential signal sources based on a candidate subset, which is associated with a lowest estimated processing demand during a subsequent receiver operating period. Then, the receiver receives spread spectrum signals from the selected set of signal sources, and based on the received signals produces position/time related data.
