GPS Satellite Launch Schedule on “Indefinite” Hold

After a series of rescheduled launch dates, U.S. Air Force (USAF) officials have placed the final two GPS Block IIR-M satellites on “indefinite” status, pending the replacement of ordnance timers used in the Delta II launcher.

In a response to inquiries from Inside GNSS, spokespersons for the GPS Wing at the Space and Missile Systems Center, Los Angeles Air Force Base, and Launch and Range Space Wing said that “based on the parts production and qualification schedule, we project the GPS IIR launches will occur in Spring and Summer 2009.”

Quellan’s GPS Receiver Noise Canceller

Quellan Inc., of Santa Clara, California, offers the QHx220 active RF noise canceller for GPS applications.

Like noise cancelling headphones, the QHx220 senses unwanted internal noise and applies an opposite signal to the receive path, using sophisticated high-speed analog techniques integrated on a single one square millimeter, low-power integrated circuit.

According to the company, the canceller provides up to 25dB of cancellation, 360º of phase coverage, and operates on a single 1.8V supply voltage.
