In early January of this year, auto parts supplier Bosch and China said that they plan to acquire 5% of HERE, a global digital map and location service provider. Before Bosch and the mainland, HERE has been favored by well-known companies such as Audi, BMW, Daimler and Intel.

For this acquisition, Bosch believes that Bosch's precise positioning service "Bosch Road Features" technology can be used to update and maintain the high-precision maps developed by HERE Maps for autonomous vehicles. Previously, Bosch had signed cooperation agreements with TomTom, Gaode Map, Baidu, and NavInfo.

Take Baidu's Apollo plan as an example, its map service is the most important part of companies that join Baidu's ecology. At present, whether ADAS level or high-precision map level, in addition to the map itself, high-precision positioning is one of the important links.

Traditional vehicle navigation systems use satellite receivers and commercial satellite services to help drivers reach their destination with positioning accuracy within a few meters. With the increased use of autopilot systems, such as lane departure warning (LDW), adaptive cruise control (ACC), automatic parking, and autopilot, safety and reliability require higher positioning accuracy.

A self-driving car is driven on the road with a lane line. Its decision on the road boundary is obtained by high-precision maps and lane line recognition systems. High-precision maps must be used in conjunction with high-precision positioning.

Recently, Chihsou, a domestic precision location service company, has reached a strategic cooperation agreement with Qualcomm Technologies and will integrate high-precision location services in Qualcomm's Xiaolong X5 LTE telematics chip for connected cars to help users achieve sub-meter high-precision positioning. The service will be introduced to the market as early as the third quarter of this year.

Chihiro's position indicates that the Snapdragon X5 LTE integrated with this service will be launched in the third quarter of 2018 at the earliest, and is expected to be used in a number of models that will be mass-produced in 2019, assisting advanced driver assistance and unmanned operation in specific scenarios. The implementation of driving applications. At present, many well-known domestic and foreign vehicle manufacturers and first-class component suppliers have confirmed that they will use the chip.

The chip is one of the major constraints that currently limit high-accuracy positioning accuracy, power consumption, and system cost.

Recently, STMicroelectronics has introduced the world's first multi-frequency satellite navigation receiver chipset for safety-critical automotive applications and decimeter and centimeter-level high-precision positioning applications for PPP and RTK applications.

Receives at least two frequencies from each satellite system (all other products receive only one frequency) by tracking all Global Navigation Satellite Systems (GNSS) simultaneously, provided by ST's automotive-grade Teseo APP (automotive-grade positioning accuracy) receiver High-quality raw GNSS data required for PPP (precise point positioning) and RTK (real-time dynamic) algorithms can achieve accurate positioning and fast convergence times around the world.

In addition to high accuracy, this industry-unique receiver also monitors the integrity of satellite data. If the accuracy is reduced for any reason, the receiver will immediately notify the system.

Also released with the Teseo APP is a Teseo V chip that also features multi-frequency precision positioning and is a simplified product developed for non-security-critical applications that do not require integrity protection. STMicroelectronics is currently providing samples for large customers that are developing autopilot systems, and is expected to install them first on high-end models introduced in 2020/2021.

U-blox, a leading provider of wireless and positioning modules and chips worldwide, recently announced the F9 technology platform to provide high-precision positioning solutions for mass-market industrial and automotive applications.

The platform combines multi-band Global Navigation Satellite System (GNSS) technology with dead reckoning algorithms and high-precision algorithms, and is compatible with various GNSS calibration data services, enabling centimeter-level accuracy. The u-blox F9 has laid the foundation for the next generation of high-precision navigation, augmented reality and driverless vehicle technology.

The u-blox F9 platform will support next-generation u-blox positioning modules for mass-market industrial and automotive applications. It uses multi-band (L1/L2/L5) GNSS signals to correct positioning errors caused by the ionosphere and provide shorter initial positioning times (fast TTFF).
