Student wins Best Presentation at CPS Week

Adwait Dongare won Best Presentation for his talk on a paper called “Pulsar: A Wireless Propagation-Aware Clock Synchronization Platform” at the Real-Time and Embedded Technology and Applications Symposium (RTAS) as part of CPS Week hosted in Pittsburgh. Advised by Anthony Rowe, Dongare's paper described a new hardware platform that uses Ultra Wide Band (UWB) radios and Chip Scale Atomic Clocks to synchronize multiple physically separated clocks to below 5ns of accuracy. Time synchronization at that level can be used for a wide variety of applications, like those found in scientific experimentation and next generation wireless systems. At that small of a time-scale, you need to automatically account for the time-of-flight speed of light delay in the messages being exchanged for setting the clocks.
