About
Technology The technology is an asynchronous GPS baseband processor architecture that minimizes power consumption while providing continuous position information. The system achieves low power by allowing all subsystems to run at their natural frequencies without clocking and all signal processing is done on-the-fly. The technology decouples crucial GPS receiver operations from power-hungry post-processing. This allows the GPS receiver to be deployed anywhere to perform only crucial receiver operations and transmits just enough information back to the base station for further processing. Based on transistor-level simulations, this system consumes only 1.4 mW with positioning errors below 4 meters, comparing favorably to other contemporary GPS baseband processors, and enabling continuous, accurate operation for extensive periods of time. A prototype system is in development.
