Cover Story

GNSS & the Law: Geolocation Privacy

Implications of Evolving Expectations in the United States

The concept of what constitutes “a reasonable expectation of privacy” from a geolocation standpoint is evolving in the United States. This change is not taking place in a vacuum. Rather, it directly results from growing concerns shared by the public, regulators, and lawmakers about the implications of a “Big Data” society.


GNSS Forum: Seven Easy Ways the Administration or Congress Could Get a Quick Win Protecting GPS and America

For more than a decade since the promulgation of a presidential directive, the United States has wrestled with the mandate to develop a backup for the Global Positioning System. A long-time navigation leader proposes some initial steps that the nation could take to enable enhanced Loran to be the system to accomplish that mission.

Mikel Miller: Science, Service, and Family

It has been a long journey to success for this scientist for positioning, navigation, and timing (PNT) science and technology development.

It’s Time for 3D Mapping–Aided GNSS

The use of three-dimensional maps supports new techniques, including “shadow-matching,” that seek to turn the disruptive effects of buildings in urban areas into a method for actually enhancing GNSS position determination.

The Particular Importance of Galileo E6C

A research team presents a brief study of the potential performance of a number of processing modes for the Galileo E6 signal, with primary focus on the relative benefits of processing the E6C pilot signal.

Practical Methods to Quantify Harmful Effects

Taken out of context, Ligado’s reworked broadband proposal might seem logical, even practical. GNSS is a positioning technology. If the positioning quality is unaffected, there shouldn’t be a problem. No harm, no foul, right?

Design Drivers and New Trends for Navigation Message Authentication Schemes for GNSS Systems

Widespread adoption of GNSS has turned into an incentive for malicious actions that exploit its vulnerabilities, by either disrupting or precisely modifying the PNT computation. Authenticating the GNSS signal at both the ranging and data levels is one way to detect and/or mitigate such threats.

How Frequencies Make a Difference in GNSS Receivers

There’s precise, and then there’s really precise. When it comes to GNSS user equipment, how do more frequencies add up to more benefits?
