200km communication link for aerial vehicle and ground station

Inquiry about the communication link for aerial vehicle and ground station

I am reaching out to inquire about Product Vcan1933, which I understand is designed for establishing communication links between aerial vehicles and ground stations. Especificamente, I require this product for the following scenarios:

Scenario 1: Point to Point Mode

Propósito: Establishing an 8 MHz bandwidth Video communication link between an aerial vehicle and a ground station.

Distance: 200 km (direct link).

Request: Please provide the Bill of Materials (BOM) and pricing for both sample purchases and bulk orders.

Scenario 2: Relay / Repeater Mode

Propósito: Extending the communication range to 400 km by adding an aerial relay.

Request: Kindly share the BOM and pricing (for samples and bulk orders) for this extended setup.

Could you also clarify the following:

Lead time for sample and bulk orders.

Available support (technical documentation, integration guidance, etc.).

Any recommended accessories or complementary products.

Adicionalmente, do you have any alternative products or solutions that may perform better than Vcan1933 for these scenarios? I would appreciate any recommendations you might have.
I appreciate your prompt attention to this request. Please let me know if you need further details from my side.

What is the communication link for aerial vehicle and ground station?

Communication links between aerial vehicles (such as UAVs, drones, and aircraft) and ground stations are essential for control, data transfer, and navigation. These links can be categorized as follows:

1. Command and Control (C2) Link

• Used for sending commands from the ground station to the aerial vehicle.
• Ensures the aircraft follows predefined flight paths or responds to real-time commands.
• Operates typically on radio frequencies (RF), such as VHF, Uhf, or dedicated aviation bands.

2. Telemetry Link

• Transmits flight data (altitude, speed, battery status, sensor readings) from the aerial vehicle to the ground.
• Helps operators monitor and adjust mission parameters.
• Usually operates on the same RF bands as C2 links.

3. Payload Data Link

• Transfers mission-critical data like video, images, e dados do sensor.
• Used in ISR (Inteligência, Vigilância, and Reconnaissance) aplicações.
• Can use high-bandwidth communication such as:
  • Wi-Fi (2.4 Ghz, 5 Ghz)
  • Satellite Links (Banda Ka, Ku-band)
  • 4G/5G networks (for urban drones)

4. Navigation and GPS Link

• Receives positioning signals from GNSS (GPS, GLONASS, Galileo, BeiDou) satellites.
• Used for precise positioning, navegação, and geofencing.

5. Beyond Visual Line of Sight (BVLOS) Link

• Required for long-range drone operations beyond direct radio range.
• Uses satellite communication (SatCom) or cellular networks for extended coverage.
• Low-latency data relays are essential to prevent communication lag.

6. Comunicação via satélite (SatCom) Link

• Used for high-altitude UAVs, military aircraft, and long-endurance operations.
• Provides global coverage using geostationary or low-earth orbit satellites.
• Opera em L-band, C-band, Ku-band, or Ka-band frequencies.

7. ADS-B (Automatic Dependent Surveillance–Broadcast)

• Used in manned and unmanned aviation to share location and flight status.
• Transmits data to air traffic control and nearby aircraft for collision avoidance.
• Opera em 978 MHz (UAT) e 1090 MHz (ES) frequencies.

Communication Technologies Used

• RF (Radio Frequency) Communication – Standard for short- and medium-range UAVs.
• Lora (Longo alcance) – Low-power, long-distance communication.
• Mesh Networks – Allows drones to communicate with each other and extend range.
• Cellular (4G/5G) – Enables BVLOS operations in areas with network coverage.
• Laser/Optical Communication – High-speed data transmission for secure links.

The choice of communication link depends on the mission requirements, faixa, data bandwidth, and regulatory constraints. Let me know if you need details on a specific type!

Do you offer any products with a 200km video range that cost less than $3000?

Currently we don’t have a UAV video data link that costs USD3000 to support 200km. If it is a full set of equipment for 200km, two transceivers are required, one for transmitting and one for receiving. As far as the current situation is concerned, the budget of 3,000 yuan is still a bit small, and only one device can be purchased.
