RF Spectrum Protection

Jules McNeff, Overlook SystemsTechnologies, Inc.

EDITOR’S NOTE: Jules McNeff answers additional questions on the subject of spectrum protection and sharing in a special “GNSS Forum” extension of this installment of the "Thought Leadership Series" in this issue of Inside GNSS.

As Mark Twain once famously told a petitioner for investment advice: “Buy land. They are not making it any more.”

So it is with radio frequency spectrum, a limited and finite resource.

Questions in Wake of New Galileo Delay

Some of the specific technical issues behind the latest delay for Galileo’s first full operational capability (FOC) satellites have already been reported. The story, as it is told, generally starts with a late navigation payload delivery by British firm Surrey Satellite Technology to the German prime contractor, OHB. Next, OHB ran into issues with the payload and the platform, further stretching out the timeline.

Due to the huge success of GPS in both military and civil applications, several other GNSSs have been developed, built, and operated in the last few decades. GNSS, regional, and augmentation systems are comprise a growing family that also includes GLONASS, Galileo, BeiDou, and Japan’s Quasi-Zenith Satellite System (QZSS). New members, such as the Global Indian Navigation System (GINS), are preparing to join in next decade.

FCC Examines Shortcomings in E911 Calls’ Location Data

Prompted by reports of a sharp deterioration in the quantity and quality of 911-caller automatic location information, the Federal Communications Commission (FCC) is weighing new requirements for phone companies to help emergency personnel find cell phone users in need of aid.

Data from emergency providers show that a rapidly declining number of 911 calls from mobile phone users come in without the accurate location information needed to find the person calling for help.

GAO Report on GPS Disruptions Faults DHS, DoT Efforts

GAO Report on GPS Disruptions Faults DHS, DoT Efforts

A General Accountability Office (GAO) report on “GPS Disruptions” issued today (November 6, 2013) concludes that the Department of Transportation (DoT) and Department of Homeland Security (DHS) need to improve their efforts to assess the associated risks and mitigate them.

The report comes nearly nine years after a National Security Policy Directive (NSPD-39) on U.S. Space-Based Positioning, Navigation, and Timing (PNT) Policy directed the agencies to develop a plan for detecting and mitigating GPS interference and develop a backup PNT capability.
