The new generation of low -power flagship chip HD8120

On August 25, Beidou GNSS satellite navigation positioning chip low -power flagship HD8120 series chips and TAU1113 and TAU1114 modules equipped with HD8120 chips were officially released. With the target of positioning performance and power consumption optimization, the HD8120 series adopts the new architecture of Cynosure III LITE independently developed to enhance the availability and positioning rate in various complex scenarios with excellent algorithms, providing better battery life for various navigation positioning applications Ability, especially suitable for smart wearable equipment, shared bicycles, drones, vehicle management and other power consumption -sensitive application markets.

Sun Zhongliang, chairman of Huada Beidou, introduced low -power flagship products HD8120

Realize stable and efficient satellite positioning globally

HD812 series single -chip GNSS SOC products, its chips and modules fully support the Beidou No. 3 signal system, adopt the Beidou BDS and GPS dual system joint positioning, support BDS, GPS, Galileo, Glonass, QZSS, and SBAS signals. Galaxy signal, GPS+Galileo and BDS or Glonass, facing the consumer application market, meet the navigation positioning requirements such as location perception, logistics and transportation.

In addition, the HD8120 series supports interference detection and dynamic filtering, distinguish complex signal interference, capture the correct signal, and its anti -interference ability can also be ease in the face of the urban canyon environment, and achieve stable and efficient satellite positioning globally. According to the measured data on the pavement, the positioning accuracy of HD8120 than similar products in different pavement environments is better than being blocked or half -open, or the satellite navigation positioning rate and positioning efficiency are equally excellent.

Low power consumption brings outstanding battery life

As a new generation of flagship products with low power consumption, the HD8120 uses the newly developed Cynure III LITE new architecture to upgrade positioning performance and optimize power consumption. With the advanced intelligent power management design, compared with the power consumption of the previous generation, the power consumption is half and performed well in actual testing. The chip also supports a wide voltage design of 1.7 ~ 3.63V voltage, and flexibly supports terminal products with various voltage design.

Optimize positioning performance to quickly wake up, speed positioning

In terms of rapid positioning, through support for the A-GNSS (Assisting-GNSS) online and offline mode, HD8120 accelerates the search tracking performance and speed, greatly shorten the first positioning time (shortened the cold start time to 3 ~ 10s), while increasing the positioning sensitivity of positioning sensitivity In the case of complicated blocking environment and weak signals, the number of satellites that can participate in positioning can also be increased, thereby improving the overall positioning performance. In addition, HD8120 supports the Star Storage function, and stores Starry data through Flash to improve the cold startup performance.

Applicable extensive mass consumer terminals to help Beidou's large -scale development

Because of the HD8120 series in terms of galaxy support, rapid positioning and low power consumption, the HD8120 series has extremely high cost performance in terminal applications such as wearable devices, drones, and trackers. There are still good positioning accuracy and position effectiveness under the weak signal.

HD820 typical application industry

Taking wearable devices as an example, the HD8120 series QFN40 5mm*5mm package size, low power consumption, offline A-GNSS and wide voltage design, reduce the design of the chip size energy efficiency aspects of the design of wearable devices, reduce charging frequency and heat dissipation, can be widely widely widespread Covering multiple fields such as smart watches, smart school emblems, student cards, pet deficits, pension help, etc., it has greatly reduced the threshold for large -scale applications of Beidou chips.

In addition, for the field of drones, HD8120 has its own single -frequency multi -system, high sensitivity, high accuracy, low power consumption, low -cost, small size, small size advantages, making drones lighter and dexterous, especially suitable for cruise drone battery life Requirements to support a wider scope of inspection.

In the field of bicycle sharing, the HD8120 series achieves high -precision positioning in Beidou in a high cost -effective manner, helping users to find cars more conveniently, combined with Beidou electronic fence technology, comprehensively optimized user cycling behavior and parking management, greatly improving the user experience. Not only that, the operating power consumption and standby power consumption performance of the HD8120 series greatly extend the battery life of the bicycle smart car lock and inject new vitality into the sensitive application market.

Adhering to the design of the integrated circuit for more than 30 years, the accumulation of the integrated circuit design and accumulation of experience, in response to the different needs of the industry, use the leading technological research and development and application capabilities to make a "good use on the Beidou". Today, Huada Beidou is actively creating the Beidou chip open platform, relying on the independent developed Cynosure III Beidou III signal system Multi -frequency and high -precision series GNSS chip to empower the development and application of enterprise algorithm for industrial chain, providing chip hardware and technology Support, help the application function secondary development, and comprehensively improve the comprehensive ability of domestic chips.
