Spectracom Releases Dual-Frequency Multi-GNSS Constellation Simulator

May 10, 2012 - By

Spectracom announced its new L1+L2 dual-frequency 32-channel multi-GNSS simulator, the GSG-62. The GSG-62 offers multiple frequency band operation, multiple GNSS constellation simulation, and expansion capability for more frequency bands and channels, the company said. The new simulator provides expanded capabilities for those who are testing more than GPS L1, according to the company. “We understand the challenges our customers have... read more

Soyuz Takes Shape in French Guiana for Dual Galileo Launch

May 8, 2012 - By

The launcher for Arianespace’s next Soyuz mission from the Spaceport in French Guiana is completing its initial checkout for a flight in the second half of 2012, which will carry another two spacecraft for Europe’s Galileo satellite navigation constellation, according to Arianespace. During activity at the Spaceport’s Soyuz Launcher Integration Building — known by its Russian “MIK” designation — the vehicle’s four first-stage strap-on boosters have been mated with the Block A core second stage, followed by integration of the Block I third stage. 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I have long been an advocate of signal diversity as a solution to many of the ills that plague the GPS user, especially outdated user equipment.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

The Evolution of Spirent GNSS Simulation

May 8, 2012 - By

Spirent’s simulation systems have changed significantly from their technology beginnings, which can be traced back to World War II radars. The company and its technology have evolved to keep pace with today’s growing population of GNSS constellations and to meet the challenges that receiver manufacturers and users encounter in an ever-complex integrated GNSS environment. read more

Massive GPS Jamming Attack by North Korea

May 8, 2012 - By

Large coordinated cyber attacks from North Korea near its border with South Korea produced electronic jamming signals that affected GPS navigation for passenger aircraft, ships, and in-car navigation for roughly a week in late April and early May. To date, no accidents, casualties, or fatalities have been attributed to jammed navigation signals aboard 337 commercial flights in and out of South... read more

Two New Galileo Satellites to Rise in September

May 3, 2012 - By

The European Commission announced a September 28 launch date for the next pair of Galileo satellites. These will launch together on a Soyuz rocket from French Guiana, joining the two Galileo in-orbit validation (IOV) satellites already in space. read more
