NovAtel has announced support for the BeiDou Navigation Satellite System on its OEM6 family and selected OEMStar GNSS receivers.
The long-anticipated BeiDou Interface Control Document (ICD) release is a
significant milestone that facilitates global acceptance of the Chinese
GNSS system into the growing range of satellite-based positioning
applications, the company says.

Spirent Communications has announced the availability of test systems with support for China’s BeiDou Navigation Satellite System in addition to GPS, GLONASS, and Galileo.
Spirent’s positioning and navigation group based in Paignton, United Kingdom, started shipping BeiDou-ready test systems to customers in 2012. The company’s equipment will now be upgraded to full BeiDou capability using the information from the recently released first full issue of the BeiDou-2 Signal-In-Space Interface Control Document (ICD).
In 2013, the annual European Navigation Conference and industry exhibition will be organized by the Austrian Institute of Navigation (OVN) and will take place at the Austria Center Vienna from April 23 through April 25. The lectures and sessions will be held in English.
The theme is Navigation – Expanding Our Horizons

Do we need performance specs for GNSS user equipment design? For a long time, the signal-in-space interface guidelines provided enough technical guidance. But times have changed.
Over the past two years, the effort by LightSquared to persuade the FCC to allow it to operate high-powered terrestrial transmitters in frequencies adjacent to GPS focused attention on potential vulnerabilities of GNSS user equipment.
