Abstract
This disclosure involves methods and systems for a GNSS receiver to ascertain its environmental context and subsequently adjust the signal processing and search algorithms to provide improved acquisition. A rapid pre-scan is performed to determine the presence of relatively strong signals. If no satellites are found in the initial pre-scan, successively more sensitive searches are conducted until at least one satellite is acquired. The information from these pre-scans is used to predict the environmental context of the receiver and correspondingly tailor the parameters for the remaining search operations.
