Introduction
Standard Background and Technology Evolution
With the surge in demand for broadband communications on civil aviation passenger aircraft, traditional VHF data links can no longer meet the needs of real-time data transmission. The MH/T 9010 series of standards introduces the LTE ground-to-air communication system, and its Part 2 proposes 28 core technical indicators for airborne terminals, marking the entry of my country's civil aviation communications into the 4G era.
System Architecture Analysis
| Subsystem | Functional Requirements | Key Technical Indicators |
|---|---|---|
| Baseband Subsystem | Signal Coding and Decoding | Support LTE-A 2×2 MIMO |
| Power Amplifier Subsystem | RF Signal Amplification | ≤160W Power Consumption |
| Power Subsystem | Dual Power Supply | Compatible with 115V/400Hz AC and 28V DC |
Core Functional Requirements
- Data communication: Provides ≥100Mbps IP transparent transmission channel
- Remote management: Supports status monitoring and parameter configuration
- Hot redundancy design: Key module MTBF ≥25,000 hours
Typical application case
After integrating the ATG airborne terminal into a certain type of business jet, the following are achieved:
1. The download rate of real-time meteorological data is increased by 8 times
2. The average delay of cabin Wi-Fi is reduced to less than 50ms
Implementation suggestions
- Give priority to 6MCU specification equipment that complies with the ARINC 600 standard
- RF wiring must meet the requirements of RTCA DO-160G Section 21
- Software upgrade function must pass DO-178C A-level certification
