پیوند داده رادیویی هوایی در باند UHF FHSS

نیاز به پیوند داده رادیویی هوایی:

باند فرکانس: فقط باند UHF (225MHz 470MHz ~) یا (320MHz 470MHz ~)

گام: 50~100mhz
FHSS rate: 500~1000 Hop/s
With IFS (Intelligent Frequency Selection)
And Anti-Jamming

Range Distance: 150~200km
تأخیر کم: 2~5 ms
RF output Power: 5~10w
رمزگذاری: AES256
Receive Sensitivity: -110 dBm

ورودی: 2xRS232 (max Baudrate: 115200BPS)

Only Serial Data Input (No Video Interface)

حالت: Point To MultiPoint (1To10)

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

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

Working Voltage: 12-36V DC
Maximum acceleration: 4g
Airspeed: <1000 کیلومتر در ساعت
Without any GNSS , وای فای, 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. فرکانس & مدولاسیون

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

2. Performance Specifications

3. Communication Architecture

  • حالت: Point-to-Multipoint (1 GCS ↔ 10 پهپاد).
  • رشته شناسی: STAR architecture (no mesh).
  • Duplex: Full-duplex between GCS (استاد) and UAVs (clients).
  • Swarm Operation: پشتیبانی می کند 10 UAVs flying simultaneously in close proximity.

4. رابط

  • ورودی:
    • پهپاد: 2x RS232 per unit (حداکثر 115,200 BPS).
    • GCS: 20x RS232 (aggregate for 10 پهپاد).
  • Exclusions: No video, GNS, دنباله دار, or Bluetooth interfaces.

5. زیست محیطی & Operational

  • ولتاژ: 12–36V DC.
  • استحکام:
    • Withstands 4g acceleration and airspeeds <1000 کیلومتر در ساعت.
    • Operates in GNSS-denied environments.

6. تعداد

  • Units: 200–250 systems.

Key Design Highlights

  • Anti-Jamming & IFS: Critical for reliability in contested/swarm environments.
  • تأخیر کم: 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, ایمن کردن, swarm-based UAV operations in challenging conditions.
