Ligado Test Results Roll In

Figures and Charts

The GPS community and Virginia-based Ligado are weighing new and upcoming test results as the standoff over interference with satellite navigation services enters its seventh year.

The dispute centers on the company’s now modified proposal to build a terrestrial wireless network supported by frequencies originally allocated for satellites. Though there had been a move some years earlier to augment the satellite services with ground stations the company’s first plan envisioned some 30,000 high-powered ground terminals.

A new reports says that the GNSS market landscape is growing because of rapid growth of satellite technology-enabled wearables, unmanned aerial vehicles (UAVs), new innovation opportunities, and low-cost precision receivers.

ABI Research’s new GNSS integrated circuit (IC) vendor competitive analysis says that Broadcom and Qualcomm remain the two top companies for the fourth straight year.

It’s Time for 3D Mapping–Aided GNSS

Figures 1-6

Real-time position accuracy, achievable in dense urban areas using low-cost equipment, is currently limited to tens of meters. If this could be improved to five meters or better, a host of potential applications would benefit. These include situation awareness of emergency, security and military personnel and vehicles; emergency caller location, mobile mapping, tracking vulnerable people and valuable assets, intelligent mobility, location-based services and charging, augmented reality; and enforcement of curfews, restraining orders and other court orders.

DGON Inertial Sensors and Systems 2016

At the 2015 symposium

The German Institute of Navigation’s (DGON) 2016 symposium on inertial sensors and systems, ISS, and gyro technology will take place in Tulla Hall at the Karlsruhe Institute of Technology (KIT) on September 20 and 21.

As modern systems for navigation, localization and guidance are increasingly making use of supporting data from non-inertial sensors, the conference particularly appreciates papers on hybrid systems, those that fuse inertial with GNSS, visual, infrared, radar or other sensors.

Let Us Now Praise

When China joined the GNSS club in 2007, it turned a satnav triumvirate into a quartet.

But some of the limelight needs to fall a little further from center stage — out there where the Indian Regional Navigation Satellite System (IRNSS) and Japan’s Quasi-Zenith Satellite System (QZSS) are not waiting idly in the wings.

Still Not a Thing, Part 2

One of the first feature articles I wrote as a newly minted GNSS magazine editor 26 years ago was about an advanced rail traffic management system based on GPS that Burlington Northern, with the help of Rockwell Collins, had designed and implemented.

NavtechGPS Seminar (NEW): Inertial Systems, Kalman Filtering and GPS / INS Integration (Course 546)

This new four-day course will take place at the Bay Club Hotel and Marina in San Diego, California, December 8-11, 2014.

It will be taught by Dr. Alan Pue, Johns Hopkins University, APL and Mr. Michael Vaujin, Aerospace Consultant.

This course is for GPS/GNSS professionals who are engineers, scientists, systems analysts, program specialists and others concerned with the integration of inertial sensors and systems, those needing a working knowledge of Kalman filtering, or those who work in the fields of either navigation or target tracking.

Proposal for U.S. eLoran Service Gains Ground

Trying to revive a years-dead federal program is usually the kind of hopeless task that even Sisyphus wouldn’t touch.

But determined supporters of eLoran are gaining ground in their effort to resurrect the cancelled radio-navigation network and, propelled by new worries over GPS jamming, they appear poised push the issue through.

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.
