PNT Advisory Board Debates Critical Infrastructure Designation for GPS

The United States’ top advisors on satellite navigation are split over the practical implications of identifying the GPS system as critical infrastructure.

At the heart of the issue is the additional protection such a designation could potentially afford the constellation particularly in the arenas of public and congressional opinion. That protection, however, could come with another layer of time-consuming and possibly constricting bureaucratic requirements.

Study: GPS Contributed More Than $68 Billion to the U.S. Economy

Study: GPS Contributed More Than $68 Billion to the U.S. Economy

GPS contributed more than $68 billion to the U.S. economy in 2013, according to the preliminary results of a new study presented to the National Space-Based Positioning, Navigation, and Timing (PNT) Advisory Board.

And the study’s author, Irv Leveson, a consultant to ASCR Federal Research and Technology Solutions, LLC, described that figure as conservative because it did not fully incorporate a host of GPS applications including those depending on GPS timing information.

GNSS-Aided Autonomous Trucks Could Save Fuel, Reduce Congestion

Block diagram of driver-assisted truck platooning (DATP) system. From “Heavy Truck Cooperative Adaptive Cruise Control” Phase 1 report

Although media coverage of autonomous or self-driving vehicles has focused on their use by private car owners, an initial report on driver-assistive truck platooning (DATP) highlights the prospects for their use in the commercial freight sector.

Titled “Heavy Truck Cooperative Adaptive Cruise Control — Evaluation, Testing, and Stakeholder Engagement for Near Term Deployment: Phase One Final Report,” the DATP project was funded by a grant from the U.S. Department of Transportation’s Exploratory Advanced Research program.

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.
