CAST Navigation: Signal Diversity and the PHGPST

May 8, 2012By

I have long been an advocate of signal diversity as a solution to many of the ills that plague the GPS user, especially outdated user equipment.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, 2012By

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

Out in Front: That’s Denial

May 1, 2012By

‘We have virtually no defense against the cyberattacks that are targeting us now, and will be in the future.” Richard Clarke served three U.S. presidents as counterterrorism czar. He wrote a fascinating — and terrorizing — article in the April issue of Smithsonian magazine, from which comes that quote. I posted it on my LinkedIn page and asked for input for this editorial. read more

Stonewalling, Mapping, Google, and Fines

April 18, 2012By

After a long investigation, the FCC hit Google with a resoundingly soft penalty for stonewalling the FCC inquiry into its controversial street-mapping program. Google was picking up a payload of sensitive information from home wireless networks from 2007 through 2010. This included emails, passwords, and Internet usage history. The FCC declared that the data collection was technically legal because the information gathered was unencrypted. However, the FCC stated that, “for many months Google deliberately impeded and delayed the bureau’s investigation” and fined Google a paltry $25,000 for their behavior. read more
