Order-of-magnitude advances in inertial technology seem to take place roughly every 20 years, and the industry is poised at such a point now. New developments in photonic technology make high-performance inertial measurement accessible at lower size, weight and power. Many applications from driverless cars to UAVs can now take advantage of positioning that can independently bridge GPS outages from 2 minutes up to 10 minutes.

Previously, controlled reception pattern antennas (CRPAs) were only in the military domain, and highly classified. The need to counter increasing GNSS signal jamming and spoofing in the civil realm has brought CRPAs into limited use there as well. How to test for their efficacy in product design and development?
A free webinar on Wednesday, March 25 from 1:00 PM – 2:30 PM Eastern Daylight Savings Time addresses the topic “GNSS Vulnerability Testing and the Controlled Reception Pattern Antenna (CRPA).” This technically rich, educational event is sponsored by Spirent Communications and Inside GNSS.

“I’ve been a revolutionist for 47 years,” Brad Parkinson began a recent invited lecture at Google, “with this stealthy revolution. GPS is indeed a stealthy revolution.” In his lecture “GPS and Humanity” he described how GPS has “stealthily” crept into the fabric of global society and created dependencies that did not exist before.

The chairman of the Federal Communications Commission (FCC) told two U.S. Senators in January that his agency could not complete a decision on Ligado Network’s license modification by the end of 2019 because of a late-in-the-year response from a key federal agency.

Trimble has introduced a compact, high-precision GNSS board designed for unmanned aerial systems (UAS): the Trimble UAS1. The board’s simple connectivity and configuration allow UAS system integrators to easily add satellite-based positioning

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).

A portable differential GPS-based precision landing system that guides aircraft in to spot landings in all weather, challenging terrain and surfaces conditions proved itself in a rapid set-up demo before military officials of five countries recently. A Raytheon team set up the company’s Joint Precision Approach and Landing System (JPALS) in less than an hour on a small footprint and promptly brought in multiple F-35Cs, long-range stealth strike fighters, to the same designated runway landing point every time over the course of six different approaches.

Safety and cost reasons led U.S. aviation regulators to choose a somewhat less efficient system for oceanic air traffic control, government watchdogs told Congress, adding that the majority of the airlines the researchers surveyed agreed with that approach.

Passengers stranded at airports is not an uncommon occurrence, but when weather does not appear to be an issue, anxious travelers can get restless searching for answers.
Over the last day or two, a number of U.S. flights were canceled as aircraft were grounded and passengers were left scratching their heads.
