  • Patent number: 7256731
    Abstract: Methods and systems are presented for controlling power cycling in a global positioning system (GPS) assembly. The assembly comprises a power management component that operates to switch a GPS receiver between at least a first mode, in which the receiver is actively receiving almanac and positioning data, and a second mode, in which the receiver does not actively receive data according to a power cycling routine of the receiver. A memory stores a plurality of quanta of almanac data as associated memory blocks, each memory block having an associated status indicating the length of time for which the associated almanac data is expected to be useful. A signal processing component processes a received signal containing at least a portion of a quantum of almanac data and identifies the quantum of almanac data within the received signal.
