On the Edge: Sensing the Rivers
A fleet of 100 robots equipped with GPS and sensors were released May 9 into California rivers to measure water flow, salinity levels, and pollution. The Floating Sensor Network is a project by the University of California, Berkeley, to improve the way water quality and flows are monitored.
Innovation: The Devil Is in the Details
The stability of a received GPS signal determines how well the receiver can track the signal and the accuracy of the positioning results it provides. While the satellites use a very stable oscillator and modulation system to generate their signals, just how stable are the resulting phase-modulated carriers?
