Behind the drone swarm formation performance isPower devices, navigation, communications, sensorsThe comprehensive upgrade of four major categories of core components, which together constitute the nerve center of the drone, has also become a key hardware base for the large-scale implementation of low-altitude economy.
1. Power system: SiC silicon carbide reconstructs battery life and energy efficiency
- Traditional silicon-based IGBTs have insufficient energy efficiency and are difficult to support long-duration formations and heavy-load flights.
- SiC MOSFET Advantages
- The on-resistance is only 1/100 of silicon-based, and the loss is reduced by 70%
- High temperature resistance, simplified heat dissipation design, reduced body weight
- Actual effect:Dual-wing vertical take-off and landing fixed-wing UAV endurance from45 minutes → 70 minutes, the formation durability is greatly improved.
2. Navigation system: Beidou + MEMS inertial navigation, centimeter-level positioning
- adoptBeidou positioning + inertial navigation + AI fusion algorithm
- Beidou: centimeter-level positioning + short message communication
- MEMS inertial navigation: continuous positioning when signal is blocked/lost
- overall positioning error< 0.5 meters, has been verified in urban logistics precision delivery.
3. Communication system: 5G + low-orbit satellite + Mesh ad hoc network
- 5G slicing: Exclusive frequency band, delay < 20ms, supports synchronization of hundreds of drones without delay response
- low orbit satellite：Fill blind areas not covered by 5G and achieve continuous communication in the whole area
- Mesh ad hoc network: Autonomous networking between drones, stronger anti-interference and invulnerability
- Huawei and ZTE have launchedAviation-specific 5G module, smaller size and lower power consumption.
4. Perception system: multi-sensor fusion to create digital eyes
- solid state lidar
- 16 lines, detection distance 200 meters, frame rate 50Hz
- Can identify obstacles with a diameter of more than 5cm
- Millimeter wave radar + AI algorithm
- Stable recognition of dynamic targets within 100 meters in rain and fog weather
- Obstacle avoidance success rate reaches99%
- multispectral camera
- Visible light + infrared + multi-spectrum in one
- Used for agricultural inspections, oil and gas pipeline monitoring, and emergency rescue
Domestic manufacturers: Sagitar Juchuang, Hesai Technology, etc. continue to reduce costs and promote large-scale popularization.
5. Industry challenges and disruptive directions
challenge
- Long aviation-grade certification cycle: 2–3 years of rigorous testing
- High-end chips/sensors rely on imports: There is a risk of supply interruption
- high cost: The price of aerospace-grade devices is more than 10 times that of consumer-grade devices.
Breaking path
- Highly integrated at chip level: Multi-module single-chip integration, reducing cost and size
- Generative AI-assisted design: Research and development cycle shortened by 50%+
- Unified industry standards: Domestic leader releases "White Paper on Intelligent Components for Drones" to promote industry chain collaboration
6. Summary: Components are the core base of low-altitude economy
Every precise formation of a drone swarm is essentiallySiC power devices, high-precision navigation, low-latency communications, smart sensorscollaborative victory.
