“聪明的车行驶在智慧的路”
"Smart car driving on the smart road"
北京海淀区的中关村软件园，不时能看到搭载激光雷达、毫米波雷达和摄像头的自动驾驶出租车在街道上行驶。打开叫车软件“萝卜快跑”，输入目的地，稍候片刻，一辆自动驾驶出租车来到身边。
At the Zhongguancun Software Park in Beijing's Haidian District, self-driving taxis equipped with lidar, millimeter-wave radar and cameras can be seen driving on the streets from time to time. Open the ride-hailing software "Radish Run", enter the destination, wait a moment, a self-driving taxi comes to your side.
在车门旁的触控屏幕上输入手机号后4位、完成身份验证后，车门解锁。在后排落座，点击屏幕上的“开始行程”，车辆平稳起步。行驶过程中，眼前的显示屏实时显示车辆及周边路况的三维建模画面，一条淡蓝色的“水波”提示接下来的行驶路线。经过红绿灯、人行道或掉头转弯处时，方向盘自动打转；遇到狭窄路段、会车等复杂场景时，车辆及时反应，保障安全。
After entering the last four digits of your phone number on the touch screen next to the car door and completing identity verification, the car door unlocks. Once seated in the back, click "Start Trip" on the screen, and the vehicle smoothly starts moving. During the journey, the real-time 3D modeling screen in front displays the vehicle and the surrounding road conditions, with a light blue "water ripple" indicating the upcoming driving route. When encountering traffic lights, pedestrian crossings, or turning points, the steering wheel automatically turns; in narrow roads or complex scenarios such as oncoming traffic, the vehicle responds promptly to ensure safety.
近年来，自动驾驶技术及产业发展加快，简单友好的用户体验，背后是感知、决策、规划、控制等多个系统，源自人工智能、5G通信、激光雷达、高精地图等多项技术的支撑。其中，北斗系统提供的高精度、高可靠的卫星导航定位服务，是不可或缺的基础能力。
In recent years, the development of autonomous driving technology and industry has accelerated. Behind the simple and user-friendly experience lies a complex system involving perception, decision-making, planning, and control, supported by various technologies such as artificial intelligence, 5G communication, LiDAR, and high-precision maps. Among these, the high-precision and highly reliable satellite navigation and positioning services provided by the BeiDou system are indispensable foundational capabilities.
“北斗卫星导航定位服务结合惯性导航技术，可提升离线高精度地图的制图效率和精度；北斗卫星导航定位服务和激光雷达定位、视觉定位等融合，形成覆盖多场景的安全定位。”百度智能驾驶事业群首席品牌官王翀说。
"BeiDou satellite navigation positioning services combined with inertial navigation technology can enhance the efficiency and accuracy of offline high-precision map mapping; the integration of BeiDou satellite navigation positioning services with laser radar positioning, visual positioning, and other technologies forms a comprehensive safety positioning solution covering multiple scenarios," said Wang Chong, Chief Brand Officer of Baidu's Intelligent Driving Business Group.
“自动驾驶意味着，聪明的车行驶在智慧的路。”中国工程院院士、国家卫星定位系统工程技术研究中心主任刘经南表示，“对于‘聪明的车’来说，响应速度要达到微、纳秒级。一辆汽车如果以100千米的时速行进，1毫秒时间内汽车已向前移动了近3厘米，就可能存在安全风险。北斗目前已经可以实现厘米级定位、纳秒级授时，能够满足自动驾驶时空位置的控制需求。对于‘智慧的路’而言，基于北斗的高精地图是行车环境信息的‘基底’，能反映出地图目标在现实世界中的准确位置，还包含更丰富的道路交通信息，实现路径规划和导航。甚至在车辆传感器失灵的情况下，高精地图还能根据路况数据主动对车辆运行实现变道减速的控制。”
"Autonomous driving means that smart cars are driving on intelligent roads," said Liu Jingnan, academician of the Chinese Academy of Engineering and director of the National Satellite Navigation System Engineering Technology Research Center. "For 'smart cars,' the response speed needs to reach the micro- and nanosecond level. If a car is traveling at a speed of 100 kilometers per hour, it has already moved nearly 3 centimeters forward in 1 millisecond, which may pose a safety risk. BeiDou can currently achieve centimeter-level positioning and nanosecond-level timing, which can meet the control requirements for space and time positioning of autonomous driving. For 'intelligent roads,' high-precision maps based on BeiDou are the 'foundation' of environmental information for driving, reflecting the accurate positions of map targets in the real world and containing richer road traffic information for path planning and navigation. Even in the event of sensor failure in the vehicle, the high-precision map can proactively control lane change and deceleration based on road condition data."
北斗系统对车载终端、路侧设备、云端平台的全面支持，让自动驾驶车辆“耳聪目明”，更加智慧高效。“车配传感器观察到的环境变化可能是一个实时的变化，与高精地图匹配后，将捕捉到的变化通过路边车联网通信节点及时上传到‘云端’，验证确认后，再将这些信息汇总于‘云’上，主动推送给需要的用户，真正实现车、路、人之间的高度协同。”刘经南说。
The comprehensive support of Beidou system for vehicle-mounted terminal, roadside equipment and cloud platform makes the self-driving vehicle "smart and intelligent", more intelligent and efficient. "The environmental changes observed by the car with sensors may be a real-time change, and after matching with high-precision maps, the captured changes will be uploaded to the 'cloud' in time through the roadside car networking communication node, and after verification and confirmation, the information will be summarized on the 'cloud' and actively pushed to the users in need, so as to truly achieve a high degree of collaboration between cars, roads and people."”Liu Jingnan said.
北斗系统提供的创新驱动力，让自动驾驶这一新生事物跑出了“加速度”：百度旗下的自动驾驶出行服务平台“萝卜快跑”测试总里程超过6000万公里，订单量已超200万；和芯星通自主研发基带芯片，与微机电惯导的深度融合可优化在楼群、隧道和高架桥等复杂环境下定位的连续性和可靠性……
The innovative driving force provided by Beidou system makes the new thing of autonomous driving run out of "acceleration": Baidu's self-driving travel service platform "Radish Run" has tested a total mileage of more than 60 million kilometers, with orders exceeding 2 million; The baseband chip independently researched and developed by Hexinxingtong and the deep integration with MEMS inertial navigation can optimize the continuity and reliability of positioning in complex environments such as buildings, tunnels and viaducts.
“北斗与5G、物联网、人工智能等新兴技术融合发展，不仅打开了自动驾驶领域巨大的市场空间，也在智慧交通领域不断拓展多样化的应用场景。”中国卫星导航定位协会会长于贤成说，目前北斗高精度智能驾驶系统已形成规模化应用发展态势，基于高精度北斗的车道级导航功能已在8个城市成功试点，并逐步向全国普及。
"The integration and development of BeiDou with emerging technologies such as 5G, IoT, and AI have not only opened up huge market space in the field of autonomous driving but also continuously expanded diverse application scenarios in the field of smart transportation," said Yu Xiancheng, President of the China Satellite Navigation and Positioning Association. "At present, the large-scale application development trend of BeiDou's high-precision intelligent driving system has been formed. The lane-level navigation function based on high-precision BeiDou has been successfully piloted in 8 cities and is gradually being popularized nationwide."

“渔船出入都能服务保障”
"The fishing boat can enter and exit the service guarantee"
浙江舟山市沈家门渔港，数千艘渔船排列整齐、桅樯林立。眼下，除钓具渔船、特许渔船可以正常外出生产，余下的1500多艘渔船在港伏休。
Thousands of fishing boats are lined up in Shenjiamen Fishing Port, Zhoushan City, Zhejiang Province. At present, in addition to fishing tackle fishing boats, licensed fishing boats can go out for normal production, and the remaining more than 1500 fishing boats are resting in Hong Kong.
“以前出海遇到险情，那真是两眼一抹黑。”58岁的船主杨岳靖，带着记者走进驾驶舱，应用了内置北斗的天通船载卫星电话、船载卫星宽带通信设备等装置一应俱全。指着船上橙黄色的北斗船舶示位仪，杨岳靖赞不绝口：“有了它，出海的渔船不仅能够精准报位，信号丢失或者发生险情时还会发送报警信息。不光能定位，咱们在海上还能收听天气预报和预警通知。”借助北斗、天通的短信及电话功能和宽带设备的应用，现在可以将实时渔获情况发送给渔商，渔运船便能迅速准确驶向捕鱼船所在位置，第一时间拉到新鲜的渔获。销售节点前移，保证了鲜度，才能卖出好价钱。
"Before, when we encountered danger at sea, it was like being in the dark." Yang Yuejing, a 58-year-old boat owner, took the reporter into the cockpit, where he had installed a complete set of equipment including a TianTong shipborne satellite phone and shipborne satellite broadband communication device with built-in BeiDou. Pointing to the orange BeiDou ship positioning instrument on the ship, Yang Yuejing praised it: "With this, fishing boats at sea can not only accurately report their positions, but also send alarm messages when the signal is lost or when there is danger. Not only can we locate, but we can also listen to weather forecasts and warning notifications at sea." With the application of the SMS and telephone functions of BeiDou and TianTong, and the application of broadband equipment, real-time fishing information can now be sent to fish merchants. Fishing transport ships can quickly and accurately sail to the location of the fishing boat, and pull in fresh catches in the first time. By moving the sales node forward, the freshness is guaranteed, and only then can we sell at a good price.
硬件设备之外，基于位置信息高速运转的渔船精密智控系统同样大显身手。
In addition to the hardware equipment, the precision intelligent control system of fishing vessel based on the high-speed operation of position information also shows its talents.
舟山市海洋与渔业局信息中心值班室内，中心主任孙平华像往常一样注视着大屏幕。屏幕上实时显示着装有北斗导航定位终端的各艘渔船信息。基于对位置信息的分析预判，142.8海里外的一艘渔船与航路上的一艘商船有碰撞风险，语音电话随即拨出：大轮航线，注意安全。随即收到渔船回复：“谢谢，我会注意观察。”
In the duty room of the Information Center of the Marine and Fisheries Bureau of Zhoushan City, the director of the center, Sun Pinghua, was watching the big screen as usual. The screen displayed real-time information about fishing boats equipped with BeiDou navigation and positioning terminals. Based on the analysis and prediction of location information, a fishing boat 142.8 nautical miles away was at risk of collision with a merchant ship on the route. A voice call was immediately made: "Large vessel route, pay attention to safety." The fishing boat replied promptly: "Thank you, I will observe carefully."
孙平华介绍，舟山市运用电子围栏划定事故多发区，有渔船驶入电子围栏划定区域，系统就会触发预警信号。“渔船出入都能服务保障。到了休渔季，渔船有移动并超出一定速度后，系统平台会对相应船只发出预警。”
Sun Pinghua introduced, Zhoushan City uses electronic fence to delimit accident-prone area, there are fishing boats into the electronic fence demarcation area, the system will trigger early warning signals. "Fishing boats are guaranteed. In the fishing season, when the fishing boat moves and exceeds a certain speed, the system platform will give early warning to the corresponding ship.”
在舟山，除了服务管理，北斗还孕育出诸多产业。
In Zhoushan, in addition to service management, Beidou also bred many industries.
嵊泗县枸杞岛的贻贝养殖基地，上万亩的养殖水域用上了基于北斗研发上线的数字化养殖管理平台。管理平台研发者、浙江同博科技发展有限公司负责人孙海说，通过安装定位设备，建立海上电子围栏，因为水域划分不明导致的贻贝养殖纠纷大大减少；北斗海洋检测浮标可以提供实时精准的水温、盐度、溶解氧、pH值、浊度等参数，帮助养殖户更好地了解水质状况和环境变化。
The digital aquaculture management platform, based on the BeiDou system, has been launched at the clam breeding base on the Gouqi Island in Shengsi County. The platform covers over 10,000 mu of breeding waters. According to Sun Hai, the developer of the platform and the head of Zhejiang Tongbo Technology Development Co., Ltd., the installation of positioning devices and the establishment of electronic fences at sea have significantly reduced disputes over clam breeding caused by unclear water area divisions. The BeiDou marine detection buoy can provide real-time and accurate parameters such as water temperature, salinity, dissolved oxygen, pH, and turbidity, helping breeders better understand water quality and environmental changes.
同博公司，是一家深耕北斗产业及海洋大数据服务领域的浙江省专精特新企业。公司研发的北斗船舶示位仪，已经覆盖了舟山当地八成以上的渔船。新近开发的带有北斗定位装置的救生衣，能够在人员落水时，自动感知并不间断报送位置信息。

“构建起巡检的精准三维坐标系”
"Construct a precise three-dimensional coordinate system for inspection"
广东佛山市狮山镇三环西路，一架搭载可见光和红外测温仪的无人机，沿着既定的铁塔航线，完成了对输电设备多个关键零器件的拍照、测温。
A UAV equipped with visible light and infrared thermometer has taken photos and measured temperature of several key components of power transmission equipment along the established iron tower route at Sanhuan West Road, Shishan Town, Foshan City, Guangdong Province.
“这次规划时间6分28秒，我们利用遥控器终端，通过账号访问北斗高精度定位主站系统，选择自动飞行作业航线，就可以完成对这几座基塔的精细化巡视。”南方电网广东佛山供电局机巡作业班班长黄丰说，北斗厘米级的高精度定位，可以准确告知无人机位置。
"The planning time of 6 minutes and 28 seconds, we use the remote control terminal, access the Beidou high-precision positioning master station system through the account, select the automatic flight operation route, you can complete the fine inspection of these towers."”China Southern Power Grid Guangdong Foshan Power Supply Bureau machine patrol team leader Huang Feng said, Beidou centimeter-level high-precision positioning, Can accurately inform the UAV position.
“依托北斗系统，构建起巡检的精准三维坐标系，通过这个空间模型规划航线、航点，无人机巡检时，不会因为误差撞上线路、变电站等。”技术人员曾懿辉在一旁解释。
"Relying on the Beidou system, build a precise three-dimensional coordinate system for inspection, through this space model planning routes, waypoints, unmanned aerial vehicles inspection, will not hit the line, substation, etc. due to errors."”Technician Zeng Yihui explained.
“绝缘子是否发热、螺丝是否松动等，这些部位最容易发生故障，以前只能凭借肉眼和手持红外测温仪来判断。”回想起10年前，黄丰和输电班要靠人工攀爬完成对输电线路的验收、故障巡查，“当高度超过40米时，能感觉到铁塔一直在摇晃，一座基塔巡下来，全身都湿透了。”现在用无人机巡检，拍照传至后台，通过点云技术开展精准分析，生成的报告会及时反馈，提醒相关部门处理隐患。
"Insulators heating, screws loosening, these are the parts most likely to fail, and in the past, we could only rely on the naked eye and handheld infrared thermometers to judge." Looking back 10 years ago, Huang Feng and the power transmission team had to rely on manual climbing to complete the acceptance and fault inspection of power transmission lines. "When the height exceeded 40 meters, I could feel the tower swaying, and when I got down from a tower, my whole body was soaked." Now, with the use of drones for inspection, photos are transmitted to the backend, and precise analysis is carried out using point cloud technology. The generated report will provide timely feedback and remind relevant departments to address hidden dangers.
通过无人机搭载激光雷达、红外测温仪、夜视摄像头等，输电线路的巡视工作大部分转为机器作业。据统计，截至2022年底，南方电网公司无人机自主巡检里程累计超100万公里，自主巡检采集的照片超过8000万张。
Through drones equipped with laser radar, infrared thermometers, night vision cameras, etc., most of the inspection work of transmission lines is turned into machine operations. According to statistics, by the end of 2022, the autonomous inspection mileage of unmanned aerial vehicles of China Southern Power Grid Corporation has accumulated more than 1 million kilometers, and more than 80 million photos have been collected by independent inspection.
“我们从2018年开始建设由北斗基准站、通信网络、数据处理系统组成的北斗地基增强系统，最终实现定位达到厘米级。”南方电网广东电网电力科学研究院北斗技术负责人鄂盛龙说，这个过程中也遇到了不少难题，“比如受太阳活动周期影响，我们处于南方低纬度地区，电离层相对更活跃，定位效果受到影响。为此，我们先后走访了武汉大学测绘学院和广东省国土资源测绘院，一并与行内设备及定位服务厂家进行了多次技术交流。”
"Since 2018, we have started to build a Beidou ground-based augmentation system consisting of Beidou reference station, communication network and data processing system, and finally achieve positioning to the centimeter level."”Southern Power Grid Guangdong Electric Power Research Institute Beidou technology director E Shenglong said, This process also encountered a lot of problems,"For example, affected by the solar activity cycle, We are in the southern low latitudes, The ionosphere is relatively more active, Positioning effect is affected." To this end, we have visited the Wuhan University School of Surveying and Mapping and Guangdong Province Institute of Land and Resources Surveying and Mapping, together with the line of equipment and positioning service manufacturers for many technical exchanges.”
“一开始，大家不习惯使用这个系统，后来随着算法的提升、技术的更迭，越来越得心应手。接下来，我们还将持续开展定位算法优化和基准站加密等工作，不断提升北斗定位可靠性。”鄂盛龙说。
"At first, we are not used to using this system, and later with the improvement of the algorithm, the change of technology, more and more handy. Next, we will continue to carry out positioning algorithm optimization and reference station encryption to continuously improve the reliability of Beidou positioning.”E Shenglong said.
目前，南方电网基于617座北斗定位基准站组成的高精度服务网，在无人机自主巡检、输电杆塔地灾监测、现场抢修应急通信等16个领域培育北斗应用场景，累计推动12万余套国产化北斗终端应用，支撑输电线路无人机自主巡检、主干电网调度领域北斗授时基本全覆盖，提升应急情况下信息传输和人员定位、车辆安全智能高效管理等能力，解决无公网或公网信号不稳定区域的电力信息传输问题，全面支撑电网数字化转型。

“有了天上‘星星’站岗，踏实多了”
"With the stars in the sky standing guard, it's much more practical."
“隐患点监测到存在变形、位移风险，请立即到现场巡查、核实。”窗外夜色渐浓，地质灾害监测员廖德华的手机被预警短信点亮，他迅速出了门。
"The hidden danger point is monitored to have the risk of deformation and displacement, please immediately go to the site for inspection and verification."”Outside the window, the night was getting darker, and Liao Dehua, a geological disaster monitor, quickly went out of the door when his cell phone was lit by an early warning message.
廖德华是四川绵阳市黄土镇莲花村村民，村子地处浅丘，常年被地质灾害困扰。他2011年搬进村，屋子前不远处的空旷平地在滑坡中塌陷了近8米，现在已变成斜坡。
Liao Dehua is a villager from Lianhua Village, Huangtu Town, Mianyang City, Sichuan Province. The village is located on a shallow hill and has been plagued by geological disasters all year round. He moved into the village in 2011, and the open flat land not far from his house collapsed nearly 8 meters in a landslide, and has now become a slope.
为了保护乡亲们的安全，老廖担任了地质灾害监测员。“在培训中学习过防灾知识，监测灾情时心里还是忐忑。”履职6年多，他的经验是多走多看，地面的情况必须一趟趟巡逻看个仔细。
In order to protect the safety of villagers, Lao Liao served as a geological disaster monitor. "I have learned disaster prevention knowledge in training, and I am still worried when monitoring the disaster."”For more than 6 years, his experience is to walk more and see more, the ground situation must patrol carefully.
2021年，当地自然资源部门为莲花村进行了滑坡治理，一批应用北斗卫星导航系统的地灾监测设备进场。“滑坡主滑方向布置了两个监测站，借助北斗系统实时采集数据，对地质灾害表面的形变位移进行监测。”行走在隐患区域，四川九洲北斗导航与位置服务有限公司工程师辜旋介绍，雨量计、裂缝计等设备安置到位，这些前端传感器能感知毫米级的微小变化，并与北斗系统相连，将数据传输至安全监测预警平台。
In 2021, the local natural resources department carried out landslide treatment in Lianhua Village, and a batch of geological disaster monitoring equipment equipped with the BeiDou satellite navigation system was brought in. "Two monitoring stations were set up in the main landslide direction, and real-time data was collected using the BeiDou system to monitor the surface deformation displacement of geological disasters." Walking in the hazard area, Gu Xuan, an engineer from Sichuan Jiuzhou BeiDou Navigation and Positioning Service Co., Ltd., explained that rain gauges, crack meters, and other equipment have been installed. These front-end sensors can detect tiny changes at the millimeter level and are connected to the BeiDou system to transmit data to the safety monitoring and warning platform.
“有了天上‘星星’站岗，踏实多了。”这两年老廖的监测担子轻了不少，只需关注预警短信，按指示及时巡查。工程师每月对监测设备进行巡检，及时校准，力求将数据误差降到最小。
"The stars in the sky are much more stable.”In the past two years, Lao Liao's monitoring burden has been much lighter. He only needs to pay attention to the early warning text messages and patrol in time according to the instructions. The engineer shall carry out monthly inspection on the monitoring equipment and calibrate it in time to minimize the data error.
走进绵阳市自然资源和规划局指挥大厅，四川省地质灾害专业监测预警平台正在运行。三维+VR全景地图上标注着密密麻麻的灾害隐患点，危害体倾角变化、降水量等数据实时传回，在平台接受分析，成为下达指令的依据。
Walking into the command hall of the Mianyang Natural Resources and Planning Bureau, the Sichuan Province Geological Disaster Professional Monitoring and Early Warning Platform is in operation. The three-dimensional + VR panoramic map is marked with densely packed disaster-prone points, and data such as changes in the tilt angle of the hazard body and precipitation are transmitted in real-time, received and analyzed on the platform, becoming the basis for issuing instructions.
2018年以来，绵阳市自然资源和规划局引入北斗系统助力防灾减灾，已累计建设地质灾害群专结合监测点1000余个。“我们可以直观看到每个点位的实时环境信息，一旦相关数据达到阈值，平台就会做出蓝黄橙红4个级别的预警。”绵阳市自然资源和规划局地质灾害防治科科长刘宏扬介绍。
Since 2018, the Mianyang Natural Resources and Planning Bureau has introduced the Beidou system to assist in disaster prevention and mitigation, and has built more than 1,000 geological disaster monitoring points. "We can intuitively see the real-time environmental information of each point, and once the relevant data reaches the threshold, the platform will issue blue, yellow, orange, and red four levels of warnings," said Liu Hongyang, director of the Geological Disaster Prevention and Control Department of the Mianyang Natural Resources and Planning Bureau.
预警发出后，基层监测员会立即前往现场反馈情况，再由自然资源部门专业人员分析决定解除警报或处置灾情。翻阅平台的处置记录，记者看到，去年平武县溪坝村滑坡隐患点出现裂缝，预警从蓝到红，裂缝周边的地质数据、走势和现场图片均在监控中，滑坡发生前周围住户就已撤离。
After the warning is issued, grassroots monitoring personnel will immediately go to the scene to provide feedback, and then professional personnel from the Natural Resources Department will analyze and decide whether to lift the alarm or deal with the disaster. Reviewing the platform's disposal records, the reporter saw that last year, cracks appeared at the landslide hazard point in Xiba Village, Pingwu County, and the warning changed from blue to red. The geological data, trends, and on-site photos around the cracks were all monitored, and residents in the surrounding area had already evacuated before the landslide occurred.
“监测精度大大提高，监测人员无法到达的山顶、断崖不再是死角，全天候监测也成功实现。”刘宏扬说。
"The monitoring accuracy has been greatly improved, the top of the mountain that the monitoring personnel cannot reach, the cliff is no longer a dead corner, and the all-weather monitoring has been successfully realized."”Liu Hongyang said.
星斗织成安全网。桥梁的倾斜、应变、震动以及过往车辆荷载；隧道的变形、结构受力、地质环境动态，借助北斗系统均能实现全面监测。“在此基础上，我们还将引入数字孪生、雷视融合等技术，对重点监测区域进行虚拟建模，借助历史数据、实时数据和算法模型实现分析预测，进一步提升灾害预警监测能力。”四川九洲北斗导航与位置服务有限公司工程部部长邓健说。
The Beidou system weaves a safety net. The tilt, strain, vibration of bridges, as well as the load of passing vehicles; the deformation, structural stress, and geological environment dynamics of tunnels can all be comprehensively monitored using the Beidou system. "On this basis, we will also introduce technologies such as digital twins and fusion of lidar, to virtually model key monitoring areas, and use historical data, real-time data, and algorithm models for analysis and prediction, further enhancing disaster warning and monitoring capabilities," said Deng Jian, Director of the Engineering Department of Sichuan Jiu Zhou Beidou Navigation and Positioning Service Co., Ltd.
据统计，截至2022年6月，“北斗+安全智能监测预警云平台”已在20个省份的水利、应急等领域布设监测点8000多个。
According to statistics, as of June 2022,"Beidou + Safety Intelligent Monitoring and Early Warning Cloud Platform" has set up more than 8000 monitoring points in water conservancy, emergency and other fields in 20 provinces.
