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.

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).

SpectraTime to Supply Atomic Clocks to IRNSS

SpectraTime has announced its receipt of a contract valued at approximately €4 million to supply rubidium space clocks for the Indian Regional Navigational Satellite System (IRNSS), a GNSS system that is under development by the Indian Space Research Organization (ISRO).

The IRNSS will consist of seven satellites, three in geostationary orbit and the other four in geosynchronous orbit. First launch of an IRNSS is currently expected in 2009. The system will transmit BOC(5,2) and BPSK signals at the L5 frequency (1176.45 MHz) and also in S-band.
