Global Navigation Satellite Systems Engineering, Policy, and Design
The long-running, high stakes battle between the GPS community and Ligado Networks may enter a new phase next month when the firm presents to the nation’s leading GPS experts its plan to develop a combined terrestrial/satellite network using its spectrum neighboring the GPS band.

The nation’s leading satellite navigation experts have invited Ligado Networks, a firm whose plans are widely viewed by many as a threat to satnav, to present at their November 15 meeting. If the company accepts, it could illuminate the structure of the terrestrial service it has in mind and either ease, or add fuel to, the ongoing dispute between Ligado and the GPS community.

General John (Jay) Raymond The ground was already shifting when Gen. John (Jay) Raymond took charge of Air Force Space Command (AFSPC) in October 2016. Just six months before, his predecessor Gen. John Hyten had announced the Space Enterprise Vision, a new way of approaching space asset development, management and protection now that space had become both contested and far more crowded. There were issues across the space, ground and user segments of the GPS program; sequestration was still looming and Congress was looking closely at how to reorganize the way the Air Force managed its space programs.

Denver, Colorado-based Lockheed Martin announced that the U.S. Air Force awarded the company a $45.5 million contract to provide Military Code (M-Code) Early Use (MCEU) capability to the Global Positioning System (GPS). Part of the Air Force’s overall modernization plan for the GPS, M-Code is an advanced, new signal designed to improve anti-jamming and protection from spoofing, as well as to increase secure access, to military GPS signals for U.S. and allied armed forces.

Federal watchdogs examining automakers’ privacy practices are urging a key regulatory agency to step up and clarify its role in protecting the location and other personal information of those operating connected vehicles. The report, posted on August 28, was just one of a number of location-privacy developments including advances in pro-privacy laws in some states and a pullback by Uber on its tracking of its customers.

The 2017 Satellite Innovation Symposium aims to pinpoint key imminent market changes that will become obvious in years to come. While infrastructure and capital status have dominated for decades, key innovations will continue to cause major disruptions to the established marketplace. What innovations will define the satellite communications industry going forward?
