الكمون المنخفض: 2~5 ms
RF output Power: 5~10w
التشفير: AES256
Receive Sensitivity: -110 ديسيبل

Input: 2xRS232 (max Baudrate: 115200نقطة أساس)

Only Serial Data Input (No Video Interface)

وضع: Point To MultiPoint (1To10)

The GCS (Master) Connect Full-Duplex To 10 الطائرات بدون طيار (Clients)

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

Working Voltage: 12-36في العاصمة
Maximum acceleration: 4ز
Airspeed: <1000 كم/ساعة
Without any GNSS , Wifi, 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. تكرار & تعديل

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

    • الطائرات بدون طيار: 2x RS232 per unit (max 115,200 نقطة أساس).
    • جي سي اس: 20x RS232 (aggregate for 10 الطائرات بدون طيار).
  • Exclusions: No video, GNSS, Wi-Fi, or Bluetooth interfaces.

5. البيئية & Operational

  • Voltage: 12–36V DC.
  • Robustness:
    • Withstands 4g acceleration and airspeeds <1000 كم/ساعة.
    • Operates in GNSS-denied environments.

6. Quantity

  • Units: 200–250 systems.

Key Design Highlights

  • Anti-Jamming & IFS: Critical for reliability in contested/swarm environments.
  • الكمون المنخفض: 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 forhigh-speed, secure, swarm-based UAV operations in challenging conditions.
