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. 具體來說, I require this product for the following scenarios:

Scenario 1: Point to Point Mode

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

距離: 200 千米 (direct link).

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

Scenario 2: 中繼 / Repeater Mode

目的: 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, 等等).

Any recommended accessories or complementary products.

另外, 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, 無人機, 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 (射頻), such as VHF, 超高頻, or dedicated aviation bands.

2. Telemetry Link

Transmits flight data (高度, 速度, 電池狀態, 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, 和傳感器數據.
Used in ISR (智力, 監視, and Reconnaissance) 應用.
Can use high-bandwidth communication such as:
- 無線上網 (2.4 GHz的, 5 GHz的)
- Satellite Links (Ka波段, Ku-band)
- 4G/5G networks (for urban drones)

4. Navigation and GPS Link

Receives positioning signals from GNSS (全球定位系統, GLONASS, Galileo, BeiDou) satellites.
Used for precise positioning, 導航, 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. 衛星通信 (SatCom) Link

Used for high-altitude UAVs, military aircraft, and long-endurance operations.
Provides global coverage using geostationary or low-earth orbit satellites.
運行於 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.
運行於 978 兆赫 (UAT) 和 1090 兆赫 (ES) frequencies.

Communication Technologies Used

射頻 (Radio Frequency) Communication – Standard for short- and medium-range UAVs.
洛拉 (遠端) – Low-power, long-distance communication.
Mesh Networks – Allows drones to communicate with each other and extend range.
蜂窩網絡 (4千兆/5G) – 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, 範圍, 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, 一個用於傳輸，一個用於接收. 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.
