Cloud drone 4G/5G remote inspection system
Cloud system=4G data transmission+4G image transmission+Remote control+Video sharing+Permission Management

The cloud drone 4G/5G remote inspection system is a set of drone 4G/5G image transmission and data transmission solutions. Based on this, we have added video sharing, permission management and other functions, which are very suitable for inspection scenarios. And it supports deploying cloud privatization on your own servers to ensure the security of your data.
Cloud system composition
The cloud system consists of LTE Link series hardware and our client. Install our LTE Link series products on your aircraft and log in to our client. After simple setup, you can use it.
Client | LTE Link series hardware |
Windows: Non attack transparent transmission | Air Link (singular transmission, does not support video transmission) |
Android:CUAV GS | LTE Link SE (integrated graphics and numbers) |
Product Features
| Data encryption transmission Air-Link 、LTE-LINK SE、 Both the client and server adopt a session dual key approach, using symmetric encryption algorithms such as CHACHA20-POLY1305 and AES_128_GCM. Fully guarantee the data security of drone communication process, prevent data tampering and parsing, and prevent man in the middle attacks in the network. |
Safe and reliable Air Link and LTE-LINK SE point-to-point communication are susceptible to interference, but Air Link maintains normal communication even under signal coverage. |
|
| Infinite Link Air Link and LTE-LINK SE rely on advanced 4G communication networks, with strong anti-interference capabilities and high data security levels. Support 4G/3G/2G automatic network switching, ensuring normal communication in areas covered by signals. The operation of the drone by the client is not limited by distance and location. Realize true drone networking. Real time performance: Under good network conditions, the data communication delay is within 30ms to 60ms. |
Automatic saving of flight recordings LTE-LINK SE is equipped with a built-in memory card, which automatically records and saves footage of the aircraft after takeoff for you to view at any time. |
|
| High definition 1080P image transmission, 250ms low latency LTE LINK SE products support 1080P real-time high-definition image transmission and have the advantage of low latency, which can be as low as 250ms in ideal environments. |
Advantages of using mobile network transmission
The communication link of the cloud system adopts 4G/5G mobile network for transmission. Compared with traditional point-to-point communication methods, it has great advantages in long-distance low altitude flight, complex environment, and many obstructions. It can communicate with drones without distance limitations in places with mobile networks.
■Unrestricted by distance ■Strong anti-interference ability

Flight data and video sharing
Teams can be created in the cloud system client, and members of the team can log in to the cloud system client to view real-time footage and flight data of any drone in the team, achieving sharing

Application scenarios
Thanks to the low latency of cloud system drone data and video, users can control drones in the command center to conduct global monitoring and patrols of various scenes. Cloud systems are highly suitable for inspection tasks in power grids, construction sites, industrial parks, ports, highways, urban security, and more.

Application Cases
Epidemic prevention and control In epidemic prevention and control, public security special police need to conduct large-scale inspections of dozens of kilometers outside the epidemic area. The inspection areas are surrounded by high-rise buildings and have complex environments with severe obstruction. Traditional point-to-point communication methods cannot meet the needs. But in epidemic areas, 4G signals are excellent, and cloud based unmanned aerial vehicle inspection systems can play a good role and share videos with multiple staff members. |

Drone competition
In drone competitions, there are a large number of 2.4G, 433MHz, and 915MHz drone communication devices, which can easily cause communication device crosstalk and mutual interference. Using a Cloud system inspection system can effectively avoid the problem of same frequency interference.
Cloud system 4G communication vs. point-to-point communication
Contact method | Cloud system 4G communication system | Point to point communication method |
Communication range | Unlimited, can be used anywhere with 4G network | Most of them are between 3-30km |
Anti-interference | Adopting carrier network, with strong anti-interference ability | There are many devices in the same frequency band, which can easily cause interference on the same frequency and be blocked by high-rise buildings, mountain slopes, etc |

ASTRA24 millimeter wave radar
Product Overview
The ISTRA24 high-performance ultra-compact altitude-holding radar features a PCBA size of only 45*45mm and weighs 6.5g, making it easily integrable into the drone's body and arms. With its innovative antenna design and highly efficient signal processing algorithms, along with real-time signal processing methods based on time-domain, frequency-domain, and phase synthesis for high sensitivity, it significantly reduces the physical dimensions of the radar module. This enables seamless integration into the drone's structural framework, opening up new possibilities for the drone industry. The millimeter-wave altitude-holding radar delivers precise height measurements within the 0.2~50m range (not recommended for prolonged hovering below 0.5m), providing exceptional convenience for drone hover flight and terrain-following operations.

Fixed altitude mode is the most important mode in drone flight control, and high-precision fixed altitude radar is the foundation for stable flight in fixed altitude mode. As is well known, fine-tuning the throttle to ensure the balance of lift and weight of the drone consumes a lot of energy for the pilot, while the fixed altitude mode of the drone achieved with the help of a fixed altitude radar can greatly reduce the difficulty of the pilot's operation. After entering the fixed altitude mode, the pilot can only control the flight direction of the drone without balancing the lift, which can greatly liberate the pilot and reduce the risk of aircraft explosion. In addition, using a fixed height radar to achieve fixed height hovering can achieve better photography effects. Not only that, the fixed altitude radar also helps to achieve stable simulated ground flight, improving the applicability of drones in specific application scenarios such as line patrol
