eLoran Antenna Park of 13 200-meter masts at Anthorn, UK.

eLoran New joint venture to ensure, assure secure PNT The founders of Chronos and UrsaNav have formed a new collaboration, named Taviga, that will focus on preserving and establishing low-frequency (LF) positioning, navigation and timing (PNT) networks in the United Kingdom, Europe and the U.S., using repurposed Loran-C or purpose-built eLoran technology. Taviga aims to ensure timing and navigation for... read more

Advocacy in the U.S. capital urges augmentation of GPS/GNSS with eLoran and other “complementary terrestrial PNT services to increase resilience.” See the Resilient Navigation and Timing Foundation’s website, rntfnd.org. This is assuredly a good thing, a worthy cause. I’ve come to believe, however, that true resilience goes beyond what we normally think of as position and timing sensors. Stimulus comes... read more

You be the judge: To eLoran or not?

December 16, 2015By

Readers of GPS World, its e-newsletters, website — and all interested PNT parties — are invited to register their opinion in the current poll at gpsworld.com/janpoll. Should the U.S. government install a full eLoran network of broadcast stations to back up GPS in case of jamming, interference or other emergencies? Yes. No. More study is needed before answering this question.... read more

Signed budget includes full GPS funding, except for $2M IIF reduction

December 16, 2015By

On Nov. 25, 2015, President Obama signed the National Defense Authorization Act (NDAA) for Fiscal Year 2016, after vetoing a previous version. The enacted NDAA complies with the two-year budget agreement, which called for a reduction in defense spending. The act reduces the GPS IIF line item by $2 million, citing “unjustified support growth” from the U.S. House of Representatives... read more

Research Online: HF beacon navigation, inertial sensors and GNSS-INS integration

December 8, 2015By

HF Beacon Navigation   Navigation using High-Frequency Ground Beacons and Ionosphere Model Corrections, by Yoav Baumgarten and Mark L. Psiaki, Cornell University. A new navigation concept relies on passive one-way ranging using pseudorange measurements of high-frequency (HF) beacon signals reflected off the ionosphere. This is being developed as a possible alternative to GNSS positioning and timing services, with benefits in... read more
