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