HRL Labs to develop inertial sensor tech for DARPA

January 3, 2017By

The U.S. Defense Advanced Research Projects Agency (DARPA) has awarded HRL Laboratories LLC $4.3 million to develop vibration- and shock-tolerant inertial sensor technology that enables future system accuracy needs without using GPS. Positioning, navigation and timing are key to ensuring the location accuracy critical to the success of modern military missions. Today’s military systems typically rely on GPS to ensure position accuracy.... read more

GNSS CEOs see bright future, alternative PNT promises well

December 28, 2016By

It has been a good year for all global navigation satellite systems (GNSS), as the chief executives of each system testify here. Alternative positioning, navigation and timing (PNT) also thrives. In this roundup of the latest highlights from the past year and forecasts for the future, 2017 augurs very well indeed! Let’s look at the newest alternative-PNT offerings first, followed... read more

Orolia fortifies resilient PNT with Satelles satellite time and location signal

December 15, 2016By

A strategic alliance announced on Dec. 15 between Orolia and Satelles includes product development and go-to-market activities of positioning, navigation and timing (PNT) solutions provided by the Iridium satellite constellation, independent of GPS/GNSS signals. The companies intend to provide PNT solutions to military, defense, government and commercial customers worldwide. Orolia, the parent of GNSS-active companies Spectracom and Spectratime, among others,... read more

Expert Opinions: Projection of 2017 PNT developments

December 12, 2016By

Q: What significant new developments in positioning, navigation or timing can we anticipate in 2017? A: With increasing focus on robust and resilient positioning, navigation and timing (PNT), the industry must respond with improved access to accurate and trusted position and timing, particularly for the warfighter. For military vehicles, this translates to a requirement for improved navigation systems that will... read more

Feedback sought on federal GPS backup plan

December 5, 2016By

The U.S. Department of Transportation is seeking feedback on the potential use by the federal government of one or more positioning, navigation and timing (PNT) technologies to back up GPS signals and ensure resiliency of PNT for critical infrastructure (CI). A Federal Register notice was published Nov. 30, with a deadline for comments of Jan. 30, 2017. The Transportation Department... read more

Make it real: Developing a test framework for PNT systems and devices

Tests of the robustness of commercial GNSS devices against threats show that different receivers behave differently in the presence of the same threat vectors. A risk-assessment framework for PNT systems can gauge real-world threat vectors, then the most appropriate and cost-effective mitigation can be selected. Vulnerabilities of GNSS positioning, navigation and timing are a consequence of the signals’ very low... read more

High plains PNT: Awareness and sense of place

October 7, 2016By

The plenary talk by John O’Keefe at ION GNSS+ stimulated a lot of neuron firing inside this old noggin. For a synopsis of “The Positioning System of the Brain,” see this column by Managing Editor Tracy Cozzens. I had the difficult task of following this brilliant scientist to the podium and introducing ION’s track chairs for previews of the conference’s... read more
