The Hangzhou daily news, Hangzhou Microelectronics Co. Ltd. successfully developed China's first Beidou navigation multimode RF baseband integrated single chip (SOC:system on chip), the chip uses a 55 nanometer process leading, the realization of China's Beidou satellite navigation technology a major technological breakthrough.
Hangzhou Zhongke micro is Chinese Microelectronics Research Academy of Sciences created Integrated Circuit Design Company. As a state-level high-tech enterprises, the company has undertaken the National Nuclear high based project, China Beidou second generation satellite navigation system of major projects and many other national projects, is the current domestic Beidou chip leader.
"Beidou satellite navigation system as the independent intellectual property rights, navigation receiver chip is one of the core technology, the key is to promote the application of Beidou system." Hangzhou Zhongke microelectronics assistant general manager Li Xiaojiang told reporters, the 55 nm chip by Beidou Zhongke micro lasted 2 years, invested about 30000000 yuan of research and development.
The chip supports China Beidou navigation system (BDS), America GPS navigation system, the Russian GLONASS (GLONASS) combined with positioning single-mode positioning and arbitrary dual-mode navigation system and three die, through software upgrades, support BDS, GPS, GLONASS, GALILEO, QZSS, SBAS six and navigation system for single-mode and multi-mode positioning. And the electronic information products of Zhejiang Province inspection and testing, the main performance index of the product, including the function, performance and power consumption to reach the domestic leading level and international advanced level.
Li Xiaojiang said, this chip integrate RF circuit, analog circuit, digital baseband circuit and the software algorithm, has realized the domestic technological breakthroughs in technology a number of areas, such as the first domestic navigation of SOC single chip, above the domestic first three mode combined with positioning, chip power and size has reached the international advanced level.
"This chip integrated navigation radio frequency chip and the baseband chip original in hardware, solves the interference problem of analog signal and digital signal, adding more power management function integration, realizes low power consumption, low cost" and Li Xiaojiang said, it can be said that the successful development of this chip, is China's Beidou satellite navigation technology a major technological breakthrough in the field of.
