Global Navigation Satellite Systems Engineering, Policy, and Design
Proponents of privatizing the U.S. air traffic control system have an apparently sympathetic ear in the White House as they renew their fight to wrest air operations from the Federal Aviation Administration (FAA).
President Trump criticized the FAA’s handling of air traffic control (ATC) modernization, pointing out the ongoing issues with NextGen during a February 9 meeting with airline executives.

‘Unprecedented’ data key to understanding radiation threats to satellites and infrastructure, and expected to provide a boost to space-weather science is now available, announced a joint release from the American Geophysical Union (AGU) and the Los Alamos National Laboratory on January 30.
As of today, more than 16 years of space-weather data is publicly available for the first time in history. The data comes from space-weather sensors on board the nation’s GPS satellites.

The American Transportation Research Institute (ATRI) released on January 25 its annual list highlighting the most congested bottlenecks for trucks in America.
Congestion chokepoints hurt the economy and the environment, so the ATRI uses GPS data collected each year to help identify times and locations that truckers will want to avoid.
