Industry highlights
Yuancosmos has been written into the local "14th five year plan" for the first time, and other provinces and cities may follow up in the future (Financial Associated Press)
The 14th five year plan for the development of Shanghai's Electronic Information Industry issued by Shanghai Municipal Commission of economy and information technology proposes to strengthen the forward-looking research and development of the basic ability of the core technology at the bottom of the meta universe, promote the development of new terminals for deepening perceptual interaction and the construction of systematic virtual content, and explore industrial applications.
Yuan universe is in the early stage of development, and the underlying technology still needs to be upgraded. According to the article "how the yuan universe rewrites human social life" on the official website of the State Supervision Commission of the Central Commission for Discipline Inspection, it is mentioned that "there is no single technology called" Yuan universe "in the world, and Yuan universe is the combination and upgrading of various existing technologies"; According to IDC's official website, as an essential infrastructure in the formation of the meta universe, the cloud computing technology, credible economic system and blockchain technology relied on for the continuous and effective operation of the meta universe platform place high expectations on users and platforms..
Inertial navigation is expected to become the standard configuration of autopilot and has broad application prospects (Financial Associated Press)
Inertial navigation has become the mainstream solution for mass production of automatic driving by many car enterprises. Xiaopeng P5 / P7 has been equipped with inertial navigation as standard, and Weilai et7, Zhiji L7, Huawei AITO, Nezha and other models will also be equipped with inertial navigation. In addition, waymo, Apollo, momenta and other automatic driving technology enterprises facing L4 route also use inertial navigation as standard hardware for automatic driving.
Inertial navigation (INS) is a navigation device based on Newton's law of mechanics, which uses inertial measurement unit (IMU) to measure the acceleration and angular velocity of the carrier, combined with the given initial motion conditions, so as to calculate the parameters such as speed, position and attitude in real time. Inertial navigation system is expected to become an essential key component in high-precision positioning of autopilot by virtue of its autonomy.
