The GCS (Master) Connect Full-Duplex To 10 UAV (Clients)

The UAV fly simultaneously next to each other. as SWARM.

작동 전압: 12-36V DC
Maximum acceleration: 4지
Airspeed: <1000 km/h
Without any GNSS , 와이파이, BT

Requirment Number: 200~250unit

With STAR architecture, we don’t need mesh.

We want to control 10 Uav by one GCS, Every UAV has 2xRS232, in Ground side, we have 20xRS232, Point to MultiPoint only.

Airborne Radio Data Link System Requirements Summary

1. 회수 & 조정

  • 밴드: UHF (225–470 MHz) 또는 narrowed (320–470 MHz).
  • Hopping:
    • 단계: 50–100 MHz.
    • FHSS Rate: 500–1000 hops/sec.
  • Anti-Jamming: Integrated with Intelligent Frequency Selection (IFS) for dynamic interference avoidance.

2. Performance Specifications

  • 범위: 150–200 km.
  • 지연 시간: Ultra-low (2–5 ms).
  • RF Power: 5–10 W.
  • 암호화: AES256.
  • 감광도: -110 dBm의 (수화기).

3. Communication Architecture

  • 방법: 지점 대 다중 지점 (1 GCS ↔ 10 uavs).
  • 토폴로지: STAR architecture (no mesh).
  • Duplex: Full-duplex between GCS (주인) and UAVs (clients).
  • Swarm Operation: 지원 10 UAVs flying simultaneously in close proximity.

4. 인터페이스

  • 입력:
    • UAV: 2x RS232 per unit (최대 115,200 bps).
    • GCS: 20x RS232 (aggregate for 10 uavs).
  • Exclusions: No video, GNSS, 와이파이, or Bluetooth interfaces.

5. 환경 & Operational

  • 전압: 12–36V DC.
  • 견고성:
    • Withstands 4g acceleration and airspeeds <1000 km/h.
    • Operates in GNSS-denied environments.

6. 수량

  • Units: 200–250 systems.

Key Design Highlights

  • Anti-Jamming & IFS: Critical for reliability in contested/swarm environments.
  • 짧은 대기 시간: Enables real-time swarm control.
  • STAR Topology: Simplifies network management (centralized GCS control).
  • Legacy Compatibility: RS232 interfaces prioritize simplicity and backward compatibility.

This system is tailored for고속, 안전한, swarm-based UAV operations in challenging conditions.
