Here’s more good press for NFER® RTLS pioneer, Q-Track. Nuclear Engineering International reports: Workers in six US nuclear power plants are being trained in a virtual radiation environment so that they can develop skills to keep radiation exposures low. The Q-Track radiation worker training system combines a software program that can […]

Q-Track NFER® RTLS Enables “Virtual Radiation”


Employing Q-Track’s patented Near-Field Electromagnetic Ranging (NFER®) technology, Collision Avoidance Non-Line-of-Sight (CANLOS™) systems allow robots to detect and avoid colliding with their human co-workers even when when direct line-of-sight may be blocked. NFER® signals use low frequencies that penetrate better and diffract around obstructions that may block conventional RF and […]

Q-Track’s NFER® RTLS: Protecting Humans From Their Robotic Co-Workers



I bought one of these Velocity Micro T301 7” Cruz Tablets and I think it’s a great value at $60. Seriously under-powered for high performance Android apps, it’s still perfect as a book reader, web browser, e-mail reader, or even for listening to music (through headphones, not the wimpy speakers) or […]

Today’s Woot: $60 Android Tablet


Q-Track’s A-Team traveled to upstate New York the other day to show off NFER RTLS for tactical training at Tactical Conference 2012. Here’s the press release: May 01, 2012 –  Verona, NY – Q-Track Corporation, the pioneer in Near-Field Electromagnetic Ranging, will demonstrate NFER Real-Time Location Systems (RTLS) products in and […]

Q-Track Demonstrates NFER RTLS for Training at Tactical Conference ‘12



A couple of years ago, I surveyed the origins of the GPS system in a Sputnik-inspired satellite navigation system that operated using Doppler shift measurements of satellite signals. The TRANSIT or NAVSAT system yielded 100m – 400m location accuracy (accounts vary). The system included several firsts: the first nuclear powered satellite […]

The Navy Navigation Satellite System – A GPS Precursor




Today’s Google Doodle honors Heinrich Hertz (1857-1893), discoverer of radio waves, on the 155th anniversary of his birth. Heinrich Hertz was not the first to experiment with radio waves. Contemporaries such as Charles Hughes and Oliver Lodge performed similar work in parallel. What set Hertz apart, however, was his tenacity […]

LightSquared, the company that sought to re-purpose their satellite spectrum adjacent to GPS to a terrestrial wireless network appears to have suffered a fatal blow to their plans. Matthew Boyle at the Daily Caller describes the politics behind LightSquared’s maneuverings as the FCC’s Solyndra. Ars Technica has a good summary of […]
