Gen. John E. Hyten, an officer deeply familiar with the GPS program whose testimony before Congress underscored the need to protect satellite navigation frequencies, was confirmed Thursday by the Senate to be vice chairman of the Joint Chiefs of Staff and the nation’s second highest ranking military officer.

A European aviation industry alliance will deploy new-generation GNSS-based landing systems, ground-based augmentation systems or GBAS, at airports across the continent, starting this year and gaining momentum in 2020. The GBAS Alliance includes airlines and aircraft manufacturers who will complementarily equip their planes with GBAS reception equipment. GBAS is recognized as a supplement to and future replacement of instrument landing systems (ILS).

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 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.
