Inertial Breakthroughs Guide the Autonomous Vehicle

The complex and mission-critical needs of the autonomous vehicle market demand innovation at higher levels in several different sensors and in sensor integration. A new photonic chip technology offers promise in providing high-volume, low-cost manufacture of high-end, tactical-grade performance fiber-optic gyros (FOGs)for inertial navigation in GNSS-obstructed environments.

FCC may act imminently on Ligado

The grapevine was abuzz on Halloween with chatter that the Federal Communications Commission (FCC) might soon act on a long-pending request from Ligado Networks to use spectrum near the GPS frequencies to support terrestrial communications.

Sifting for gold in the GSA’s new GNSS Market Report

The European GNSS Agency (GSA) has just issued its sixth annual GNSS Market Report, a booklet that comprehensively runs down the major market sectors and gives gratifying growth figures for all of them.  This is not news, strictly speaking.  This is more of the same that we have seen over the last two decades, the last six years of which have been quantified in the sturdy GSA Market Reports.

CYGNSS satellites use reflected GPS signals to predict hurricane paths

The Cyclone Global Navigation Satellite System (CYGNSS) constellation operated by the U.S. National Aeronautics and Space Administration (NASA) consists of eight miniature satellites that use GPS signals bounced off the sea surface to measure wind speeds. One after the other at 12-minute intervals, the satellites pass over tropical storms, gathering data that can be used to predict the storms’ path and their intensity.

Lessons to be Learned from Galileo Signal Outage

Every GNSS has experienced a failure. On January 26, 2016, an error in the GPS data upload system caused incorrect data to be transmitted from the satellites on the L1 band used by most commercial GPS receivers. Th e problem was resolved within six hours, although some users experienced problems for as much as twelve hours. Th e next day, the US Air Force (USAF) released a full statement explaining that the problem was caused by ground system soft ware when one satellite was decommissioned.

Ultra-Wideband Re-Emerges As GPS Interference Issue

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. In June, Robert Bosch LLC formally requested the Federal Communications Commission (FCC) do what it said it would do back in April 2002: reexamine controls on UWB that the FCC itself called “extremely conservative” when they were written. The request is not to change the rules—not just yet anyway—but for the FCC to launch a rulemaking process that could eventually lead to changes in the rules. And Bosch wants a lot of changes.
