Global Navigation Satellite Systems Engineering, Policy, and Design
Seventeen years after federal regulators restricted a promising wireless technology to protect GPS and other spectrum users, they are being asked to loosen those limitations. Ultra-Wide Band (UWB) proponents insist the strictures are too tight and cut off their ability to innovate.

The basis of all precision positioning and navigation is precision timing. Timing comes first. GPS Time is defined on the basis of a set of atomic clocks orbiting aboard the satellites and on the ground in monitoring stations; similarly for the other GNSS systems.

The Chinese are closing in on the completion of the BeiDou constellation with 39 satellites now on-orbit and more launches planned, an official told a conference on aerospace technology innovation.
Yang Jun, deputy director of China’s Satellite Navigation System Management Office, told attendees at the Shanghai event that the plan is to loft five to seven more satellites into place this year and another two to four in 2020, according to the Xinhua news agency.

The U.S. National Aeronautic and Space Administration (NASA) has activated an orbiting ultra-precise atomic clock orbiting aboard a spacecraft provided by General Atomics Electromagnetic Systems. If the clock performs as well in space as it has in the lab, losing only one second every 10 million years, the technology could enable far-reaching deep space missions—and improve the accuracy of GNSS timing and positioning.

The second Lockheed Martin-built GPS III space vehicle (GPS III SV02)—also known as Magellan—was recently encapsulated within its protective fairings in preparation for Thursday’s scheduled launch. GPS III will launch tomorrow from Space Launch Complex-37 (SLC-37) at Cape Canaveral Air Force Station, Florida.
