Chip Transition-Edge Based Signal Tracking for Ultra-Precise GNSS Monitoring Applications
This novel concept of monitoring chip asymmetry can extend the state of the art in the areas of GNSS signal-quality monitoring and authentication. Tracking GNSS signals using their underlying spreading sequence chip transition edges reveals positive versus negative chip asymmetries that are characteristic to each satellite. This asymmetry is due to various types of natural signal deformation that is known to occur within the satellite’s signal generation and transmission hardware. read more

Out in Front: Oh, the Wonder

August 6, 2015 - By

Of it all. Of the broad expanse of the world and all its inhabitants, its layers, its depths and heights, the atmospheric mantle in which it wraps itself, its floating mountains of ice and its solid soaring peaks of rock and snow, its savage predators, and all its shades of human endeavor. Every August we marvel at the many applications of global positioning science, at real-world instances of hardware and software in the service of humankind and of Gaia itself. read more
