Introduction
Standard Overview
MH/T 4053-2022 was issued by the Civil Aviation Administration of China and specifies the technical requirements for the data interface between the civil drone traffic management information service system and the drone system, operation control system and supervision system. The standard will be officially implemented on August 1, 2022 and is applicable to data exchange scenarios for domestic drone operations.
Core functional architecture
| Functional modules | Main capabilities | Data interaction frequency |
|---|---|---|
| Airspace information management | Controlled airspace/suitable airspace mapping and publishing, geographic fence maintenance | Dynamic update |
| Flight application management | Airspace application, flight plan approval, release confirmation | Business triggering |
| Air traffic services | Flight dynamic monitoring, violation warning, traffic situation push | ≥2 seconds/time |
Key technical requirements
Communication protocol
- HTTPS secure transmission protocol
- JSON is used for message format
- Interface authentication is managed by (appId, appKey) key pair
- The message body needs to be digitally signed and encrypted
Data element specification
Typical flight dynamic data element: Contains 12 mandatory fields such as longitude (WGS84 coordinates, accurate to 0.0000001°), latitude, altitude (meter-level accuracy), speed (0.1m/s accuracy), and heading angle. It is required to be reported every 2 seconds, with a delay of no more than 1 second.
System interaction architecture
The standard defines four types of core interface relationships:
- Real-time data interface with UAV system (flight dynamics reporting/airspace information distribution)
- Business interface with operation control system (flight plan application/status query)
- Approval interface with airspace supervision system (airspace application/approval document synchronization)
- Authentication interface with real-name registration system (UAV/operator information verification)
Performance indicators
| Indicator type | Required value | Test method |
|---|---|---|
| Flight dynamics interface TPS | ≥2000 | Appendix C Dynamic Monitoring Test |
| Flight Application Response Time | ≤500ms | Appendix B Functional Test |
| Data Storage Redundancy | ≥1 copy | Chapter 9.3 Verification |
Implementation Suggestions
Development Notes
- Strictly follow the metadata format of Appendix A (for example, airspace data must include 6 mandatory fields such as grid code and altitude layer)
- Personal privacy data (ID number, etc.) must be encrypted during transmission
- The flight dynamic interface must implement a breakpoint-resume transmission mechanism
Test Points
Key points to verify:
- Interface idempotence (repeated request processing)
- Coordinate conversion accuracy (WGS84/CGCS2000 coordinate system support)
- System stability under high concurrent pressure (supporting more than 10,000 drones online at the same time)
