Wi-Sys Launches Quadrafilar GPS Antenna

Wi-Sys Communications Inc., based in Ottawa, Ontario, Canada, has launched the WS1551QF L-band + GPS (L1) Quadrifilar Helical Antenna.

An active right-hand circularly polarized, quadrifilar helical antenna, the WS1551QF provides an omni-directional, cardoid radiation pattern, with peak gain optimized at elevation angles between 0° and 40°. The wideband antenna covers both the L-band downlink frequency band (1525 to 1560 MHz) and the GPS (L1) frequency band (1574 to 1576 MHz).

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

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.
