    BEIJING, Aug. 19 (Xinhua) -- The following is a summary of science and technology news of China.

    5G-ASSISTED UNMANNED DELIVERY CAR

    An unmanned delivery car with 5G wireless technology hit the roads in the city of Nanjing, capital of east China's Jiangsu Province.

    The white mini car, with a height of about 0.5 meters, was launched in Jiangbei New Area by Suning Logistics, a subsidiary of Chinese e-commerce giant Suning to support the company's smart retail service. The car's self-driving performance has been greatly improved, allowing it to pass traffic lights on its own and at a faster speed, with a normal average operating speed of 8 km/h, up to 15 km/h. It can also detect obstacles 100 meters away and avoid them.

    VOICEPRINT RECOGNITION PROJECT

    A cloud-based voiceprint recognition project has been launched in the city of Ulanqab in north China's Inner Mongolia Autonomous Region.

    The project is to provide reliable logon authentication solutions to Internet users via voiceprint recognition technologies.

    The services of the project will be made available to users in neighboring Ningxia Hui Autonomous Region and provinces of Gansu, Qinghai and Shanxi in the next two to three years.

    HIGH-RESOLUTION SATELLITE IMAGERY FOR LAND SURVEY

    Satellite remote sensing imagery with high resolution has been used in China's ongoing third national land survey.

    Surveyors have used satellite imagery with a resolution of one meter as base maps, which can distinguish objects that measure tens of square meters on the ground.

    If county-level surveyors in field investigations find the land status is inconsistent with that on the satellite images, they will take photographs with location and azimuth information, for later verification by superior departments. Enditem
