GPS BDS Beidou Dual-mode Zhongke ATGM336H satellite positioning timing Module/GP-02 | Электронные компоненты и

Features: Low power consumption 25mA, positioning accuracy of 2.5 meters. High sensitivity, antenna self-test and protection, timing accuracy 30ns, 10Hz output. Can directly replace MAX series of GPS modules, the main interface signal Pin-Pin compatible, installation hole consistent.

Can be used in the car, shipboard positioning and navigation, high-precision timing, wearable equipment, sharing bicycles and other fields.

With BDS system completing the Asia Pacific Network, GLONASS system to realize the full constellation deployment and the modernization of GPS system, multi-system integration has gradually become the development trend of network RTK technology. An important development trend in the international navigation community is multi-mode positioning.Beidou (China), GPS (United States), GL ONASS (Russia), GALILEO (EU) four global systems can have up to 140 satellites to provide positioning signals, multi-mode combined positioning and single-GPS positioning can greatly improve the "urban Canyon" environment of satellite occlusion problems, making positioning more accurate, higher positioning rate, The effectiveness of positioning has been improved by one step, which is helpful to obtain reasonable positioning effect in the harsh environment such as community, street, elevated and so on.

Without increasing the cost, upgrading to multi-mode positioning is already a big trend of intelligent positioning equipment.

October 2014, Zhongke Micro leading domestic counterparts, the first to introduce RF baseband integrated single-chip AT6558, for the domestic satellite navigation positioning chip set a new benchmark.

1. The chip belongs to the fourth generation navigation chip of Zhongke, and has four main application features:

2. BDS GPS Dual-mode joint positioning, support to replace the single GPS function on the export product.

3. Three-mode continuous operation of power consumption is 23mA 3.3V, low power consumption up to the international advanced level.

4. QFN40 Package (5mmX5mm), the solution size is greatly reduced, can support wearable products.

Selling price is comparable to foreign chips, very competitive in the market.

1. Basic knowledge

What is BDS? BDS is the abbreviation of Beidou satellite navigation system with fully independent intellectual property rights in China. Is the third mature satellite navigation system following the GLONASS of the United States global satellite positioning System (GPS) and the Russian Global satellite navigation system (GLONASS). Beidou system is divided into Beidou generation and Beidou second generation from the project implementation. The Beidou second-generation satellite is currently in orbit and operates 14 satellites, covering the Asia-Pacific region.

China plans to achieve global coverage 2020 BDS.

What is GPS? GPS is the full name of the Global Positioning system, initially led by the United States military construction, because of a good technical foundation and widely civilian.

The market likes to navigator, locator and other equipment collectively referred to as "GPS", in fact, these positioning terminals are carrying a GPS chip that supports receiving GPS satellite signals and realizing positioning.

What is GALILEO? GALILEO is the EU's global satellite navigation system.

2014 was in the experimental phase, launching 4 experimental satellites. "GP-02" is a new generation of science and technology based on the two generations of independent research and development of RF baseband integrated navigation SoC chip independent research and development of the module, with low power consumption, small volume and other characteristics, the first support of BDS GPS dual-mode joint positioning, terminal equipment to replace the single GPS module, or increase the Beidou positioning function of the best choice.

Can support customers in TRACKER,OBD, positioning the bracelet, Campus card and other smart devices to upgrade the multi-mode positioning function.
