DJI Mavic 3 Earns C1 EU Exam Certificate, in a World’s First

DJI Mavic 3获世界首个C1欧盟测试证书

Shenzhen, China-based DJI, the world’s leading drone manufacturer, has been granted the first C1 EU-type examination certificate allowing drones to operate under the new European drone regulation framework.

位居深圳的大疆创新，是世界领先的无人机生产商，近日获得了首个C1欧盟测试证书，遵循欧洲无人机规定，操作无人机。

TÜV Rheinland, the international testing service provider charged with certifying civilian unmanned aerial vehicles for operating in European Union-affiliated countries, announced the granting of the certificate on August 18.

德国莱茵技术检验协会（TÜV），负责欧盟成员国民用无人机检验的国际性测试服务机构，在8月18日授予其证书。

The testing agency’s experts “comprehensively tested the Mavic 3 system from manufacturer DJI for compliance with the drone class C1 requirements of the new regulation (EU) 2019/945,” TÜV Rheinland said in a statement.

测试机构的专家对大疆的Mavic 3系统对于C1级欧盟新规定2019/945的合规性进行了全面的检测。

In a press release, DJI said the C1 certificate, which requires the user to update to C1-compliant firmware, brings a number of advantages to the company.

在记者发布会上，大疆表示C1级证书，要求使用者需要将固件更新至C1级，为公司创造了巨大的优势。

“Users can fly in the new A1 Open Category and will no longer have to pass the complex and costly A2 “Remote Piloting License” exam. They will have more freedom to fly in environments they have been restricted from without the C1 certificate – unless obtaining special permission after an additional lengthy administrative process,” the company said.

该公司说到，“飞手能够在A1开放类别下进行无人机飞行，而不再需要通过复杂且昂贵的A2级“远程飞行证书”测试。有了C1证书，他们操作无人机的环境受限变少，能够更加自由地飞行无人机；而不像以前需要通过长时间的执行审批。”

The C1 certificate is valid across the European Economic Area, which comprises the EU plus Norway, Iceland and Liechtenstein, and applies to all hardware and C1-updated-firmware of the current DJI Mavic 3 series.

C1证书的有效区域贯穿整个欧洲经济区，包括欧盟成员国以及挪威、冰岛和列支敦斯登，适用于大疆创新Mavic 3系列所有的硬件和C1级更新固件。

In order to comply with the certification, DJI had to prove the Mavic 3 system met strict standards pertaining to mechanical strength and safe controllability in a wide range of flight and operating conditions. In addition, Class C1-certified systems are required to have, among other things, a remote-identification system and a reliable data link as well as a data interface for a geo-awareness system to comply with the EU’s airspace limitations.

为了获得该证书，大疆创新需要证明Mavic 3系统在各种飞行和操作条件下符合机械强度和安全可控性的严格标准。此外，C1级认证系统需要具备一个远程识别系统，一个可靠的数据链接以及地理识别系统的数据界面，遵循欧盟的航空限制。

Under the European Drone Regulation, C1-certified drones with C1-compliant firmware are also subject to additional mandatory changes. The company said the Mavic 3 series currently meets the EU’s new noise-reduction level of 83db. Other changes, which will be activated whenever any C1-certified DJI Mavic 3 drone is flown in the European Economic Area (EEA) include:

配置C1固件的C1级认证无人机，需符合欧洲无人机规定，同时也会有一些强制性变化。该公司表示Mavic 3系列当前符合欧盟新规降噪幅度83db。所有C1认证大疆Mavic 3无人机在欧洲经济区飞行是需要做出的改变包括：

· When the ActiveTrack Intelligent Flight Mode is used to film people or objects, the distance from the person/object will be limited to 50 meters (164 feet). Beyond 50 meters, ActiveTrack will be disabled;

当以动态跟踪智能飞行模式拍摄人物或物体时，摄距需要限制在50米（164英尺）。超过50米距离，动态跟踪模式会自动失效。

· The drone’s auxiliary LEDs will be turned on or off automatically during use, based on the actual environment, and;

无人机自带的LED灯在使用过程中会根据周边的环境自动打开或关闭；

· The LEDs at the front arms of the drone will blink by default for the duration of the UAV being powered on.

无人机前臂的LED灯闪烁表示无人机开启过程中出现错误

“once the C1 application process has been launched, all future firmware updates of the Mavic 3 series will include the technical changes required by the C1 certificate and cannot be reversed,” DJI said.

一旦开始进行C1申请手续，则 Mavic 3系列所有固件更新都需要通过C1证书所需的技术性变化，并且不能撤销。

The application process for obtaining the new C1 class identification label for the Mavic 3 series is scheduled to be available to all customers the fourth quarter of 2022. once the application process is opened, users can easily access it on a voluntary basis at no cost. The process will require users to provide their drone serial number and confirm that they have updated to the firmware needed to obtain C1 certification.

2022年第四季度的所有客户都可以进行Mavic 3系列获取C1级识别标号申请流程。一旦开始申请，用户无需任何费用，便可自行操作，且流程简单。需要提供他们的无人机序号和保证他们的固件已更新到C1级所需。

“For TÜV Rheinland, this certification is also special because it is the first time in our 150-year history that we have certified an aircraft for its flight safety characteristics,” said Stephan Scheuer, TÜV Rheinland’s head of the Technical Competence Center of Unmanned Aircraft Systems.

莱茵技术检测协会无人机系统技术能力中心负责人Stephan Scheuer表示，“对于我们协会来说，此次认证也很特殊，因为这是在我们150年历史以来首次因为飞机的飞行安全特性而获得认证。”

The EU regulation divides unmanned aerial systems into classes from C0 to C6. Class C1 devices are those that weigh less than 900 grams (about two pounds) and includes commercial drones most frequently used in photography and filming. TÜV Rheinland is accredited by the German Accreditation Body for all seven classes of drones and is thus qualified to carry out the technical tests, as well as being designated by the German Federal Office of Civil Aeronautics to assess and issue the EU type examinations.

欧盟规定将无人机系统分为C0到C6级。 C1级设备为重量小于900克（大约2磅），包括用于摄影摄像的商用无人机。德国认证机关对莱茵技术检测协会所有七级无人机都进行了认证，因而有资格实施技术检测，并且受德国联邦民用航空局委派，评估并执行欧盟类检测。

DJI said that in addition to the obtaining the C1 certification for its Mavic 3 series, the company is committed to complying with the new European Drone Regulation for all other existing and future drone models, and it will work with regulatory agencies to obtain additional drone certificates over the coming year.

大疆创新表示除了Mavic 系列之外，公司所有现有及未来发行的无人机模型都将遵循欧洲无人机新规。并且接下里他们也将与管理机构合作获取更多的无人机证书。

Researchers Help Underwater Drones Detect Ocean Contaminants, Like Oil Spills or Gas Leaks

研究者帮助水下无人机探测海洋污染物，如油气泄露

The U.S. Navy has awarded Worcester Polytechnic Institute (WPI) researchers Nikolaos Gatsonis and Michael Demetriou with $347,843 for the development of a computational model utilizing data from a system of autonomous underwater vehicles (AUVs) or underwater drones to provide real-time evaluations of the concentration and source of a contaminant liquid or gas plume as it circulates throughout the ocean. Upon being deployed on an AUV network, the estimator could assist in determining responses to chemical or biological threats, accidents, and environmental disasters.

美国海军给予伍斯特理工学院（WPI）研究者Nikolaos Gatsonis和Michael Demetrious奖金共 $347,843，表彰其对于数据利用计算机模型的开发，通过水下无人机系统提供海洋内液体或气体污染源及浓度的实时评估，有助于应对生化威胁、事故和环境灾害。

“Locating the plume source and estimating in real-time the concentration of a liquid or gas plume in ocean waters is complex but critical,” explained Gatsonis, head of WPI’s Department of Aerospace Engineering. “With better, faster detection and estimation of underwater plumes, the Navy and other agencies could respond to intrusions, submerged airplanes or vehicles, people who are trapped, and contaminants that should be contained or remediated.”

伍斯特理工学院航空工程部部长表示，“确定污染源位置并实时预估海水中气体或液体污染物的浓度过程十分复杂，但是也极具关键性。如果能更好且更快地探测和预估水下污染物及其相关数据，海军和其他相关机构也能及时处理应对各种情况包括入侵、浸没的飞机，受困的人群以及需要处置的污染物。”

As co-principal investigators on the three-year project, Professors Gatsonis and Demetriou will develop algorithms capable of being carried out quickly on the underwater drone hardware. 

Gatsonis和Demetriou教授作为该项目的主要研究者，将开发能够快速运行水下无人机硬件的算法。
