GNSS high-precision positioning plays an indispensable role in intelligent driving

GNSS-based high-precision absolute positioning plays an indispensable role in intelligent driving. Compared with high-precision relative positioning sensors such as vision and radar, it is not affected by weather, light, etc., and can help cars achieve precise positioning in all scenarios, providing a reliable basis for intelligent decision-making. To achieve high-precision positioning, it is inseparable from the "three major components" of high-precision positioning - hardware, services, and algorithms. Their roles are similar to the core three elements of traditional automobiles - chassis, engine, and transmission.

But to truly achieve mass production, the 'three major components' of high-precision positioning must be upgraded to version 2.0, which are integrated hardware, proprietary services, and intelligent algorithms.

Integrated hardware: integration to improve development efficiency

In the past, due to the lack of integrated hardware, the application of high-precision positioning in intelligent driving vehicles had many inconveniences. From component selection, system integration to testing and verification, each link required facing countless choices. A wrong choice at one step might require starting over. In recent years, SpatiX has joined hands with partners to create a variety of hardware integrated with high-precision positioning services, including dual-frequency centimeter-level modules and single-frequency communication-navigation integrated sub-meter-level modules. Choosing these integrated modules eliminates the need to worry about a series of issues such as component selection, system integration, and testing and verification, greatly improving the integration rate of mass-produced vehicles.

In addition, considering the complexity of the final usage scenarios of automobiles, SpatiX has also launched many easily integrable hardware products on roads and in venues.

Proprietary services: Tailor-made to ensure delivery

Ordinary satellite positioning can only achieve a maximum accuracy of meter-level. Services are the biggest variable introduced in high-precision positioning and the core secret to achieving centimeter-level positioning. Currently, SpatiX Cors Center is tailor-made for the mass production of intelligent driving and proposes three major categories of indicators: accuracy, reliability, and safety. Accuracy covers position accuracy, attitude accuracy, speed accuracy, initial positioning time, etc. At the same time, high-precision services have achieved 100% coverage across the country (except no-man's land), and the service availability rate has reached 99.99%; the service integrity risk indicator is 10^-7/h, which means that the service has only one false alarm in 10 million hours, comparable to aviation industry standards; at the same time, the service R&D process meets standards such as Aspice, functional safety, SOTIF, and TISAX.

At the delivery level, SpatiX has set up a dedicated solution design team, R&D delivery team, and key customer service team to improve communication efficiency, help automotive customers better control the mass production rhythm, and ensure that mass-produced models are launched as scheduled.

Intelligent algorithms: Fully verified by 300,000 kilometers of actual testing

With integrated hardware and proprietary services, intelligent algorithms are ultimately needed to complete the final closed loop. In the complex environment of intelligent driving, it is necessary to design better algorithms for more scenarios and have sufficient responses to error situations to handle them with ease.

The battle-tested intelligent algorithms are the last barrier to mass production.
