Modular GPS Software Radio Architecture

Software radio technology provides advanced signal processing and multi-band multi-mode software-based RF receiver capabilities. When applied to GPS, this software radio technology provides the ability to add in new GPS waveform applications through only software and/or firmware modifications to the GPS receiver. A major benefit of this approach is that GPS users will no longer be forced to purchase new GPS hardware if their needs change or to take advantage of next generation GPS capabilities. Software applications to fit changing requirements can instead be used to upgrade the GPS software radio. GPS receivers will also not require unique GPS hardware but can be implemented as one of multiple waveforms being processed on a single software radio.
