At the same time, it is equipped with a sky-end ADS-B In dual antenna as standard, supporting a receiving range of 20 kilometers. Combined with the DJI O4 Transmission Industry Enhanced Version, the maximum effective signal distance can reach 40 kilometers (FCC standard). Even in high-interference environments such as dense buildings and mountainous areas, it can maintain stable signals and ensure uninterrupted operation throughout the operation. In addition, the GNSS multi-satellite positioning system combined with RTK technology achieves high-precision positioning of 1 cm + 1 ppm horizontally and 1.5 cm + 1 ppm vertically, with a maximum hovering accuracy of ±0.1 meters, providing a solid guarantee for precise operations.

In-depth Ecological Opening: Empower Multi-scenario Innovative Applications

Adhering to the concept of "in-depth opening and win-win cooperation", DJI has deeply integrated the M400 with Manifold 3. Through the PSDK development kit, Manifold 3 applications can be efficiently developed in only 4 steps, realizing seamless collaboration between computing power and the flight platform, and building a diversified industrial solution ecosystem. This in-depth opening not only breaks the barriers between hardware and software, but also allows third-party developers to customize exclusive applications adapted to their own industry needs based on the M400 platform, promoting the continuous expansion of industrial application scenarios.

The tethered power solution is an important achievement of the M400's ecological upgrade. It is equipped with DJI's first original industrial tethered battery TB100C, adopting the standard Qiaoheli KR2+6 connector, supporting E-Port 2 coaxial development, and can push the tethered cable length through PSDK to ensure flight safety. The tethered system can convert single-phase AC power into high-voltage DC power, continuously supply power to the drone, and achieve 12-hour ultra-long endurance continuous work. Combined with a high-power lighting system, it can realize air-ground power supply and lighting, which is widely used in scenarios that require long-term fixed-point high-altitude operations such as curtain wall cleaning, emergency lighting, communication relay, and real-time monitoring. Combined with the BS100 multi-functional battery box, the M400 also supports third-party airport development. The battery box main board adds third-party airport battery switch, charging and stop-charging protocols, supports battery wake-up function, and cooperates with the MSDK slow-rotating propeller function to realize unmanned on-duty operations such as autonomous cruise, automatic charging and automatic return of the drone, extending the operation capability boundary.

The upgrade of real-time mapping and surveying capabilities makes the M400 an efficient tool in the field of surveying and mapping modeling. Based on the powerful computing power of Manifold 3, the M400 can deploy real-time SLAM and orthophoto fast stitching algorithms, realizing the subversive experience of "mapping while flying and generating maps upon landing", shortening the time delay of traditional aerial survey data processing from "hour-level" to "minute-level" or even "second-level", and building a full-link closed-loop solution of "aircraft-side collection → Manifold 3 reconstruction → cloud rendering → terminal decision-making". When equipped with a five-lens tilt camera, it can realize full-scenario applications such as close-range photogrammetry, monomer modeling and terrain-following flight. Combined with Gaussian splatting technology, it clearly restores the details of ground objects, meeting the high-precision needs of urban real-scene 3D modeling, geological disaster assessment, urban planning and other fields.
