IEC Announces New Miniaturized, Secure GPS Receiver Module

IEC TruTrak Evolution GPS Receiver


L-3 Interstate Electronics Corporation (IEC), based in Anaheim, California, has announced its latest miniaturized GPS receiver, the TruTrak Evolution.

A single-board, L1/L2 24-channel secure GPS receiver, the TruTrak Evolution consists of a security module, radio frequency down converter and I/O logic. The receiver employs IEC’s latest key data processor (KDP II) SAASM chipset in the XFACTOR module to provide enhanced GPS security.

Agricultural and Energy Prices Driving GNSS Products and Services

Agricultural and Energy Prices Driving GNSS Products and Services

From the perspective of consumers, the yearlong rise in commodity prices — from oil and natural gas to corn and wheat — has clouded the economic outlook. But for producers, including many GNSS manufacturers and service providers, those clouds have silver linings.

Recent financial reports from companies active in agricultural and natural resource markets bear this out. GNSS products used to guide and control equipment are in heavy demand as are real-time differential correction services, particularly those using global satellite-based systems.

Sunny and Hot! A perfect month for a solar car race

Sunny and Hot! A perfect month for a solar car race

Continuum soaks up the rays in Sioux Falls, South Dakota.

A sleek-looking solar car built by a University of Michigan team was first across the finish line early in the afternoon of July 22 after a long, hot 10-day 2,400-mile (4,000 km) race from Plano, Texas to Calgary, Alberta. And once again GPS and satellite-based differential corrections play a key role.

This year, 15 solar-powered cars built by students from universities in the U.S., Canada, and Germany completed the 2008 North American Solar challenge.

Michigan has won five out of nine NASC races, held every other year since 1990.

Boeing Will Build GPS IIF Satellites on New ‘Pulse’ Line

The Boeing Company will use its new “pulse line” process for assembling satellites to build GPS Block IIF satellites for the U.S. Air Force.

Constructed at the company’s facility in El Segundo, California, the new process is expected to shorten the time needed to build a space vehicle and will eventually be implemented on all Boeing satellite production lines.

For the Block IIFs the new process will reduce the travel distance of a space vehicle from 12,000 feet to 10,000 feet, according to John Duddy, director of GPS programs for Boeing.

Openmoku Plans Publication of Mobile Phone Schematics, including GPS Chip

Neo FreeRunner (GPS chip, lower left, #3)

Okay, they’re really serious about open source.

Mobile device manufacturer Openmoko has announced that it will publish the schematics for the company’s Neo 1973 and Neo FreeRunner mobile phones, further opening its mobile platform to the development community.

u-blox AG, Switzerland, maker of the GPS chip — the u- ANTARIS 4 ATR0635 — used in the Neo FreeRunner, endorsed Openmokos publishing the complete schematics for the GPS chip in the Neo FreeRunner phones.

GIOVE-B Signal Observations Confirm MBOC’s Multipath Advantage

GIOVE-B Signal Observations Confirm MBOC’s Multipath Advantage

Standard deviation of code multipath for Galileo signals transmitted by GIOVE-B. The two thicker lines show the L1BC modulations: BOC(1,1), light green, and CBOC (dark green).

Initial results from observations of the Galileo GIOVE-B satellite conducted by researchers at the European Space Agency (ESA) and Septentrio Satellite Navigation indicate that the multiplex binary offset carrier (MBOC) modulation outperforms the BOC(1,1) modulation on the L1 (data + pilot channels) frequency in mitigating the effects of multipath or reflected signals.

Air Force Hopes for November, December Launches of Final GPS IIR-Ms

UPDATED SEPTEMBER 10 2008: With replacement parts currently being manufactured for faulty components that have delayed launch plans, Air Force GPS program managers hope to get the final two modernized Block IIR satellites on orbit by the end of the year.

A tentative launch date of November 7 has been targeted for the Block IIR-20(M), which will carry a payload that includes an experimental L5 signal. If all goes well, the final IIR launch would take place by December 31.
