Inside GNSS Columnist Gathers Another D.C. Correspondent Award

Dee Ann Divis, an Inside GNSS contributing editor who writes the magazine’s Washington View column, continues to garner journalistic awards.

On June 9 she received the Society of Professional Journalists D.C. Chapter’s award for 2015 “Washington Correspondent” for a series of articles on unmanned aerial systems (UAS) published in Inside GNSS last year.

Her 2015 award citation for the series entitled “Empty Skies” emphasized the “well-detailed and comprehensive handling of a complex subject. . . .”

Septentrio Absorbs Altus Positioning

Belgian GNSS manufacturer Septentrio Satellite Navigation, of Leuven, Belgium, has announced the completion of the acquisition and integration of Altus Positioning Systems, based in Torrance, California.

Septentrio Satellite Navigation and Altus-PS started working together in 2007. The collaboration between the two companies has already resulted in a series of such surveying and GIS-focused products as the APS-NR2, APS-3, APS-U, and APS-GeoPod. The smart antenna form factors will form a separate product line in the Septentrio product portfolio.

OriginGPS Launches Miniature GPS/GLONASS Module

OriginGPS has announced the launch of the Multi Micro Hornet, a patented, GPS/GLONASS antenna module targeting developers of “wearables” and other devices that require a small form factor, low power consumption, and high sensitivity.

The module measures 20x10x5.9 millimeters, has a signal tracking sensitivity of –165dBm, according to the company. It incorporates OriginGPS’s patented and proprietary Noise Free Zone (NFZ) technology designed to provide high sensitivity and noise immunity under marginal signal conditions.

Septentrio Launches OEM Receiver Targeting UAS

AsteRx-m UAS

Septentrio has launched its AsteRx-m UAS, an OEM GNSS receiver specially designed for the unmanned aerial systems market.

According to the Leuven, Belgium–based company, the AsteRx-m UAS — Septentrio’s smallest receiver — provides real-time kinematic–level positioning accuracy with low power consumption, less than 600 milliwatts with GPS alone and less than 700 milliwatts with GLONASS.

Hundreds of Drones Approved as FAA Eases Limits

Work to integrate drones into the nation’s regular air traffic picked up speed over the last eight months as aviation regulators found new ways to permit unmanned flights while still keeping the skies safe for other aircraft.

In September 2014 the agency announced the first of what is now more than 450 waivers enabling commercial companies to begin for-profit operations in the United States.

DoT Completes 2014 Federal Radionavigation Plan

The federal Department of Transportation (DoT) Office of the Assistant Secretary for Research and Technology has released the 2014 Federal Radionavigation Plan (FRP) signed by the U.S. secretaries of defense, transportation, and homeland security.

The FRP is published every two years and provides an overview of the current planning and policy for U.S. positioning, navigation, and timing (PNT) systems.

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.

Contract Supports New Tests of eLORAN as GPS, PNT Backup

Exelis, UrsaNav, Inc., the Department of Homeland Security’s Science and Technology Directorate (DHS S&T), and the U.S. Coast Guard (USCG) have entered into a cooperative research and development agreement (CRADA) to test and demonstrate enhanced Loran (e-LORAN) service from former LORAN-C sites.

These sites are the legacy ground-based radio navigation infrastructure of the decommissioned LORAN-C service that could be retained and upgraded to provide eLORAN low frequency service.

Estimating the Short-Term Stability of In-Orbit GNSS Clocks

Global navigation satellite systems provide position, velocity, and time (PVT) solutions to users whose receivers calculate position based on one-way ranging from satellites. As is well-understood, a key step in the positioning process involves a determination of the difference between the time of signal transmission identified in the satellite’s broadcast navigation message and the time of its reception by user equipment.

Unmanned aerial vehicles (UAV) are finding increased application in both domestic and governmental applications. Small UAVs (maximum take off weight less than 20 kilograms) comprise the category of the smallest and lightest platforms that also fly at lower altitudes (under less than 150 meters).

Designs for this class of device have focused on creating UAVs that can operate in urban canyons or even inside buildings, fly along hallways, and carry listening and recording devices, transmitters, or miniature TV cameras.
