A friend in Texas has confirmed that Loran signals are now up and
receivers are showing position. I am including a note from UrsaNav
regarding this event.
TIME FOR LIFE
UrsaNav Testing Wide-Area Timing Alternative
February 29, 2012. This week, for the first time since August 2010,
advanced Low Frequency (LF) signals, including eLoran are on air in
North America. As a result of a Cooperative Research and Development
Agreement (CRADA) between the United States Coast Guard and UrsaNav,
Inc. live testing of a wide-area precise timing solution has begun.
These initial tests include a comprehensive pallet of signals, including
eLoran, that are being evaluated for their ability to provide a robust,
wide area, wireless precise timing alternative that can operate
cooperatively with GPS, or during periods of GPS unavailability.
Globally, government, industry, and academic experts recognize that
enhanced LF signals, such as eLoran, can provide alternative timing,
either as a standalone service, or as a component of a Position,
Navigation, and Timing (PNT) service. The LF signals operate
independently of Global Navigation Satellite Systems (GNSS), such as
GPS. This recognition has led to a cooperative approach, such as the
CRADA, for testing and examining the benefits of a wide-area timing
solution.
Additional on-air tests are planned at various sites throughout the
United States. Broadcasts will test several different frequencies,
waveforms, and modulation techniques using evolutionary,
state-of-the-art technology. Reception of these broadcasts are planned
at both on-shore and off-shore locations, and will include advanced LF
data delivery techniques. The results of these trials will be presented
at national and international conferences. Any party interested in any
part of the trial, or interested in doing their own measurements are
invited to contact us.
UrsaNav is uniquely positioned to help achieve the CRADA goals. We
provide the worlds most advanced solutions for Low Frequency Alternative
Positioning, Navigation, Timing, and Data, including high performance
eLoran Timing Receivers. We have partnered with Symmetricom, the global
leader in precise time synchronization, and Nautel, the industry-leading
supplier of high-power RF transmitters. This “alliance of expertise”
provides the foundation technology for the best wide area, terrestrial
based alternative to satellite systems such as GPS. GLONASS, and Galileo.
