Chinese mainland chip vendors have pioneered the launch of Global Navigation Satellite System (GNSS) chips that support the Beidou system. Due to the bid for a state-owned automobile system in mainland China, it is mandatory that the car navigation system must support the Beidou satellite system and subsidize the relevant local supply chain manufacturers. At this stage, Beijing Dongfang Lianxing, Herui Xingtong and Chengdu Guoteng have all launched GNSS chip supporting Beidou satellite system.
Wang Tangxing, director of business development for the Global Satellite Positioning System (GPS) business unit of Broadcom ’s Mobile and Wireless Business Group, said that since the Chinese mainland officially launched the Beidou Navigation Satellite System on December 27, 2012, it has The civil space signal interface control file (ICD) is open. Therefore, local mainland manufacturers have successively launched GNSS chips supporting the Beidou satellite system from 2011 to 2012. Currently, buses or other transportation vehicles that can receive Beidou satellite positioning signals have been successively launched in China. The mainland is on the road.
However, although mainland Chinese manufacturers can be the first foreign chip manufacturers to launch GNSS chips that support Beidou navigation satellite systems, due to technology limitations, not only are the functions not highly integrated, the size cannot be reduced, and because of the small number of production, the price is expensive, so they are in the market The competitiveness is not enough to attract foreign countries to actively enter the mainland China market.
Taking Broadcom as an example, using 40 nanometer (nm) complementary metal oxide semiconductor (CMOS) process technology, a small size, low power consumption and GNSS chip that can support the Beidou navigation satellite system is developed. It is expected to be in the second half of 2013 roll out.
Wang Tangxing emphasized that Broadcom ’s latest mass-produced product, BCM4752, can support GPS, GLONASS, QZSS, Galileo, Wide Area Augmentation System (WAAS), Assisted Global Navigation Satellite Positioning System (AGNSS) and Satellite Baseline Enhancement System (SBAS), etc., can now receive more than 60 satellite signals, coupled with the Beidou navigation satellite system support, can enhance the company's competitiveness in the market.
The latest Windows has multiple versions, including Basic, Home, and Ultimate. Windows has developed from a simple GUI to a typical operating system with its own file format and drivers, and has actually become the most user-friendly operating system. Windows has added the Multiple Desktops feature. This function allows users to use multiple desktop environments under the same operating system, that is, users can switch between different desktop environments according to their needs. It can be said that on the tablet platform, the Windows operating system has a good foundation.
