A method is provided for acquiring a signal from a satellite in a global navigation satellite system. The signal includes a pseudorandom code. The method includes, for each time period of a plurality of time periods: generating samples of the signal, segments of the samples of the signal are correlated with a local copy of the pseudorandom code, thereby producing correlation values for the time period. A discrete Fourier transform is performed using, as inputs, the correlation values for the respective time period, thereby producing a frequency representation of the correlation values for the time period. The frequency representations of the correlation values for the plurality of time periods are combined according to a data hypothesis. When a magnitude of the combined frequency representations meets predefined criteria, a frequency corresponding to the magnitude is selected as a tracking frequency for the satellite.

A receiver device includes an acquisition engine and a reconfiguration engine. The acquisition engine uses a first circuit size. The acquisition engine is configured to receive a first signal including a plurality of first satellite vehicle signals, and identify a first satellite vehicle based on the first signal. The reconfiguration engine is configured to receive an indication that the acquisition engine identified the first satellite vehicle, and responsive to receiving the indication, generate a reconfiguration file defining a second circuit size less than the first circuit size. The reconfiguration engine is configured to cause the acquisition engine to be reconfigured based on the reconfiguration file to use the second circuit size.

A method for generating a physical model of a path from GPS data. The method involves receiving GPS data defining a path from a GPS-enabled device and receiving a digital terrain model for an area that includes the path. An area of interest along the path is then identified and the GPS data associated with the area of interest is smoothed. The digital terrain model is sampled along the path and an elevation of the path is smoothed using a weighted average of the digital terrain model and the GPS data to create modified path data that is scaled to produce a first ribbon that is printed.
