Product Survey on GNSS Receivers

去年，由于它们逐渐发展为真实导航系统，因此我们由GNSS（全球导航卫星系统）替换了GPS（全球定位系统）一词。这里列出的接收器代表旨在实现调查准确性的高端细分市场。

A recent newspaper article headlined "Made in China Rapidly Changing to Made by China" reported a 33% increase in registration of patents of Chinese origin in 2006 compared to 2005. With an annual 170,000 registrations, China now holds third place in the world after the US and Japan (source: World Intellectual Property Organization (WIPO). So it is surprising that we welcome to our current Product Survey just one new Chinese GNSS receiver manufacturer, China HuaCe, founded in 2002 and based in Shanghai. It is rumaired, other Chinese and Asian manufacturers are ready to launch new instruments atIntegeo 2007. Although Hemisphere GPS is a new name it was formerly known as CSI wireless Inc. Another newcomer is Altus Positioning Systems.

OEM

原始设备制造商（OEM）是指从专用制造商那里获取产品或组件的公司，并将其纳入自己的产品，并以自己的品牌名称将其带入市场。OEM产品的使用也已找到了GNSS接收器的方式。例如，Trimble将其所有GPS子系统的制造分包给Solectron Corporation。由于OEM董事会构成了许多GPS接收器的基础，因此包括Hemisphere GPS，Novatel和Septentrio制造的董事会作为示例。

GNSS趋势

The technological trend is towards integration of GNSS with other techniques. Seamless navigation from outdoor to indoor or from gate to gate, for example, can only be achieved by integrating GNSS with other sensors and data. On the consumer market, mobile phones are gradually becoming equipped with a GPS or GNSS chip, and it is true that, as with Lidar, new applications depend not so much on technological constraints as on the limits of human imagination. Galileo input is still limited; the EU and USA recently agreed on collaboration. And how will the Chinese Beidou system develop? See for an answerthis month's Pinpoint.
