NovAtel, L-3 Interstate Electronics Partner on Civil RTK and SAASM Receiver Card

May 30, 2012 - By

NovAtel Inc. today announced the development of its OEM625S Selective Availability Anti-Spoofing Module (SAASM) GNSS receiver, a collaborative effort between NovAtel and L-3 Interstate Electronics Corporation (IEC). System integrators have come to rely on the centimeter-level positioning accuracy made possible with real-time kinematic (RTK) commercial GPS receivers. Many authorized defense customers rely on access to the Precise Positioning Service (PPS)... read more

Lockheed Martin Completes Navigation Payload Milestone for GPS III Prototype

May 29, 2012 - By

The Lockheed Martin team developing the next generation Global Positioning System III satellites has completed a major integration and test event on the program’s satellite pathfinder, known as the GPS III Non-Flight Satellite Testbed (GNST). The milestone is a key indication that the GPS III team is on track to deliver the first satellite for launch availability in 2014. In... read more

Guest Editorial: Commercial GPS Receivers See Combat Action

May 23, 2012 - By

This month we present a guest column by James D. Litton, who attended the 2012 GPS Partnership Council, jointly sponsored by the Armed Forces Communication and Electronics Association and the U.S. Air Force GPS Directorate. The key topic of this year’s council quickly emerged as the tension between commercial off-the-shelf GPS receivers and official military issue; the two are used side-by-side in active military theaters. read more

MBOC Signal Furor

May 23, 2012 - By

A subsidiary of the UK Ministry of Defence has been granted a UK patent on the MBOC signal design, which was a product of lengthy and cooperative negotiations between U.S. and European scientists. The UK patent, taken in the names of two UK scientists participating in the project, is being used by a legal firm to demand royalty fees from... read more

LightSquared Bankrupt, But Spectrum Void Still Beckons

May 15, 2012 - By

By Alan Cameron. LightSquared, the company that mounted a powerful threat to GPS signals, declared bankruptcy on May 14, after losing a lengthy struggle in the court of the Federal Communications Commission (FCC) with the GPS industry, the U.S. military (behind the scenes), the Federal Aviation Administration, and many other GPS users. However, the vacuum into which Lightsquared sought to... read more

CAST Navigation: Signal Diversity and the PHGPST

May 8, 2012 - By

I have long been an advocate of signal diversity as a solution to many of the ills that plague the GPS user, especially outdated user equipment. The best equipment, if it were available today, would be the PHGPST or Perfect Handheld GPS Transceiver. I cannot count the thousands of letters and emails from warfighters, first responders, and civil users who immediately see the value of software-defined receivers and want to know where to purchase the PHGPST. For now, some early GPS software-defined user equipment does exist, but to reach the goal of the PHGPST receiver manufacturers must first be able to accurately and reliably simulate/generate all the diverse PNT (position, navigation and timing) signals available, which include some signals not ordinarily categorized as PNT signals today. Certainly not an easy task; however, there is hope. Recently I heard about a small GNSS/INS simulation company that may be paving the way to the PHGPST — CAST Navigation in Tewksbury, Massachusetts. read more

Indoor Positioning: Overhyped or Just What LBS Needs?

May 8, 2012 - By

Because LBS Insider’s deadline is this week, CTIA coverage from New Orleans is not included in this month’s column. Janice Partyka, editor of GPS World’s Wireless Pulse, is covering CTIA in the Crescent City for the latest location-based services, M2M, and connected vehicle news. So instead of talking about CTIA (and why there aren’t many pure LBS players or sessions there anymore), this column examines the hype surrounding indoor positioning — is it LBS’ savior, or just another technology that may, or may not, pan out? read more
