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

Range Distance: 150~200km
कम अव्यक्ता: 2~5 ms
RF output Power: 5~10w
कूटलेखन: AES256
Receive Sensitivity: -110 डी बी एम

इनपुट: 2xRS232 (max Baudrate: 115200बीपी)

Only Serial Data Input (No Video Interface)

तरीका: Point To MultiPoint (1To10)

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

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

कार्य वोल्टेज: 12-36डीसी में
Maximum acceleration: 4जी
Airspeed: <1000 किमी/घंटा
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. आवृत्ति & मॉडुलन

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

2. Performance Specifications

  • रेंज: 150–200 km.

  • RF Power: 5–10 W.
  • कूटलेखन: AES256.
  • संवेदनशीलता: -110 डी बी एम (RECEIVER).

3. Communication Architecture

  • तरीका: पॉइंट-टु-बहु (1 GCS ↔ 10 यूएवीएस).
  • टोपोलॉजी: STAR architecture (no mesh).
  • Duplex: Full-duplex between GCS (मालिक) and UAVs (clients).
  • Swarm Operation: समर्थन 10 UAVs flying simultaneously in close proximity.

4. इंटरफेस

  • इनपुट:
    • यूएवी: 2x RS232 per unit (मैक्स 115,200 बीपी).
    • जेंटलमैन कैडेट: 20x RS232 (aggregate for 10 यूएवीएस).
  • Exclusions: No video, GNSS, वाईफ़ाई, or Bluetooth interfaces.

5. पर्यावरण & Operational

  • वोल्टेज: 12–36V DC.
  • मजबूती:
    • Withstands 4g acceleration and airspeeds <1000 किमी/घंटा.
    • Operates in GNSS-denied environments.

6. मात्रा

  • Units: 200–250 systems.

Key Design Highlights

  • Anti-Jamming & IFS: Critical for reliability in contested/swarm environments.
  • कम अव्यक्ता: 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 forउच्च गति, सुरक्षित, swarm-based UAV operations in challenging conditions.
