09/21/2009 - Spirent Showcases New Developments in GPS/GNSS Testing

Spirent demonstrates its complete GPS modernization and multi-GNSS simulator portfolio at ION GNSS 2009

Paignton, United Kingdom – (September 21, 2009) – Spirent Communications plc (LSE: SPT), the leading provider of navigation and positioning test solutions, today announced that it will demonstrate its new GPS modernization and multi-GNSS product range at ION GNSS 2009. For the first time ever, event attendees will have access to live demonstrations of Spirent's full range of GPS modernization and multi-GNSS simulators, including the GSS8000 Multi-GNSS Simulator, GSS6700 Multi-GNSS Simulation System and GSS6300 Multi-GNSS Signal Generator.

Today, navigation and positioning technology is no longer just about GPS L1 and L2. GPS is being modernized to include M-code, L2C and L5; the GLONASS constellation is nearly complete; and new systems including QZSS, Galileo and Compass are on the way. The GNSS landscape presents several market opportunities with GNSS applications becoming more mainstream and available in a growing number of devices.

"Multi-GNSS offers significant opportunities and challenges to GNSS technology, system and application developers," said John Pottle, marketing director of Spirent's positioning technology division. "In the future, most commercial receivers will be multi-GNSS. Spirent has committed to providing the necessary test tools required by GNSS technology developers. GPS plus GLONASS is of particular interest today, as GLONASS now offers enough satellites to be a useful compliment to GPS, improving availability in built-up environments. If you are not currently working on multi-GNSS, you likely will be soon."

Spirent's comprehensive product offering supports both GPS modernization and multi-GNSS testing:

GPS Modernization Testing
  • The GSS8000 GPS/GNSS Constellation Simulator is fully approved to support SAASM, AES M-code and SDS M-code testing. In addition it supports anti-interference testing, CRPA testing and can be used for integrated GPS/Inertial testing.
Multi-GNSS Testing
  • The GSS8000 Multi-GNSS Simulator provides up to 3 constellations (GPS/SBAS, GLONASS and Galileo) in a single chassis. GPS configurations can also support QZSS.
  • The GSS6700 Multi-GNSS Simulation System offers multiple channels of coherent GPS/SBAS, GLONASS and/or Galileo L1 signals from a single chassis.
  • The GSS6300 Multi-GNSS Signal Generator provides a single channel of GPS/SBAS, GLONASS and/or Galileo L1 signals for production testing on commercial GNSS receivers.
