00:00:50Asking for an opportunity to show one's talents.
00:00:53This is a human desire that has existed since ancient times. Today, with surveying and mapping technology,
00:00:56the position, altitude, and direction of objects on Earth
00:01:00are determined. This provides a basis and a standard.
00:01:04Since the completion of the Beidou satellite navigation system in 2020, Beidou has been sending
00:01:18navigation and positioning signals from space to the ground. The Ministry of Natural Resources has integrated
00:01:21nearly 7,000 base station resources, connecting them into a network across the country.
00:01:25This ground network continuously observes Beidou signals,
00:01:29performs calculations and corrections, becoming an important ground enhancement
00:01:33node for Beidou's high-precision applications. The Beidou in the sky provides a unified spatiotemporal signal.
00:01:36The ground base stations further correct the orbital and atmospheric propagation errors in the signal.
00:01:40The two work together to support everything from safeguarding national security to optimizing urban governance,
00:01:44from supporting major projects to benefiting people's lives.
00:01:48Surveying and mapping technology with high-precision positioning
00:01:51goes from sky to earth, weaving a security and service network
00:01:54that is invisible yet constantly at work.
00:01:58The construction caused deformation of the pipeline,
00:02:04and there are other different reasons. So as the city continues to advance,
00:02:08these risk sources will be exposed more and more. For a megacity like Tianjin,
00:02:12the gas pipeline network has exceeded 54,000 kilometers.
00:02:15With the acceleration of urban renewal, roads are widened, buildings are constructed,
00:02:19and various underground pipelines crisscross. Leakage risks are often hidden
00:02:22in the invisible underground space.
00:03:00To find leakage points in such a huge pipeline network
00:03:04is like looking for a needle in a haystack. This car is a Beidou gas leak detection vehicle.
00:03:07It uses high-precision PPB level gas detection
00:03:11to quickly calculate where there are gas leaks along our route.
00:03:15Precisely locating underground leak points
00:03:18does not rely solely on Beidou signals from space. Beidou provides autonomous and controllable meter-level positioning,
00:03:22while ground-based satellite positioning provides accurate coordinates.
00:03:25Through the high-precision services provided by the national satellite navigation
00:03:29and positioning base station network, it is transmitted back to the scheduling system
00:03:33in real time. The gas company can determine the risk location
00:04:13and organize emergency repairs in the first instance. So how to precisely locate
00:04:16the leak points in the complex underground pipeline network?
00:04:19In fact, it has been carried out
00:04:26through surveying and mapping technology as early as the pipeline construction stage.
00:04:46精准定位地下的錄點
00:04:49靠的不只是來自太空的北抖號,
00:04:53北斗解決了自主可控的米級定位,而地面上的衛星定位
00:05:42to make judgments, but can quickly locate the leak point
00:05:46along the digital map. Urban gas management
00:05:49thus moves towards full-process, full-space refined management.
00:05:53If the time is not synchronized and there is a difference of one second,
00:05:57we need to process it and use automatic detection
00:06:01to greatly improve the positioning accuracy of the leak points.
00:06:05From spatial positioning to time synchronization,
00:06:08Beidou's timing function connects Beidou satellites,
00:08:13ground base stations, and users. The standard time is sent to users,
00:08:17so that you can receive our national standard time
00:08:21anywhere in the world. And the accuracy of this time
00:08:23is very high. Our national Beidou's timing accuracy is 21 seconds.
00:08:27It makes everyone unify the time.
00:08:31We can do all kinds of information exchange, navigation and positioning,
00:08:35and production events under this unified spatiotemporal
00:08:38reference. To lay the spatiotemporal foundation
00:09:12for large-scale application of Beidou,
00:09:27in August 2024, the Ministry of Natural Resources centrally integrated nearly 7,000
00:09:30base stations to build a national satellite navigation
00:09:34and positioning base station network, implementing unified planning,
00:09:38unified standards, and unified management of base stations.
00:09:41Precision agriculture
00:10:12should provide reliable spatiotemporal 基底 for high-efficiency applications.
00:10:16Our network is a 24-hour uninterrupted reception of satellite signals.
00:10:20If the regular network is interrupted,
00:10:23the monitoring equipment can switch to
00:10:27Beidou short message communication, and can transmit data
00:10:31through Beidou satellites. We all know that
00:10:34this short message is a unique advantage of our Beidou system.
00:10:37It mainly transmits data through zenith satellites,
00:10:41completely independent of ground base stations. Another important
00:10:45advantage of Beidou's short message sending is that
00:10:49it can carry precise positioning information.
00:10:53Beidou satellites and the base station network
00:12:55work together. They not only provide precise spatiotemporal
00:12:58support for all walks of life, but also subtly integrate
00:13:02into people's lives, becoming indispensable
00:13:06in daily travel. We are currently exploring
00:13:10unmanned farm intelligent control operations.
00:13:13The continuous integration of technology is changing their traditional
00:13:17farming methods. Once this is generated,
00:13:21you perform unmanned operations. This path will be uploaded
00:13:24to our platform in real time, and you can directly view
00:13:28its operations on the platform. No operation is required.
00:13:32Up to now, it has been a thousand-level and hierarchical
00:13:36system. There are two Beidou antennas on the base station.
00:13:39Beidou positioning is mainly obtained by the antenna.
00:13:43It mainly ensures that the unmanned harvester is in real-time operation.
00:13:47As long as the position it sees deviates from this line,
00:13:51it will automatically correct its direction back to this line
00:23:50to achieve its precise operation.
00:23:53Beidou unmanned agricultural machinery
00:23:57uses high-precision positioning information,
00:24:01combined with visualized digital farmland high-precision maps,
00:24:05to achieve automatic driving,
00:24:06turning, and U-turns. The core of an unmanned
00:24:10farm is to transform
00:24:17human experience and physical strength into data
00:25:20insights and machine execution. It brings about a three-layer
00:25:23revolution in efficiency, cost, and sustainability.
00:25:27Technology not only transforms the traditional
00:25:31farming model of thousands of years, but also illuminates
00:25:35the future blueprint of modern agriculture:
00:25:39efficient, green, and sustainable.
00:25:43Today, with the Beidou satellite and base station network
00:25:47as the core, the space-ground collaborative model
00:28:05deeply integrates satellite remote sensing, UAV aerial
00:28:09survey, and ground IoT sensing and other
00:28:13multi-dimensional surveying and mapping methods, building an integrated
00:28:17space-air-ground monitoring network, supporting a national
00:28:20spatiotemporal intelligent infrastructure.
00:28:24Surveying and mapping and geographic information
00:28:28have risen to become a strategic, fundamental,
00:28:30and core information resource
00:28:38of the country. It is both a new
00:28:41pioneer of development and the first guardian
00:28:45of security. In the process of national
00:28:49modernization, it plays an irreplaceable and critical
00:28:51supporting role. In the future, spatiotemporal
00:28:55intelligence will also be deeply integrated into every
00:28:59inch of national governance. Standing higher,
00:29:03so we can see further. China Central Television.
