Telemetry transmission system RCtoSky 3DR V6

Order the RCtoSky 3DR V6 telemetry transmission system for your drone - get full control over the flight!

RCtoSky 3DR V6 telemetry transmission system for drone - This is an important communication channel between your device and the ground station. It transmits real-time data about the state of the quadcopter. You will be able to see battery voltage, altitude, GPS coordinates and other parameters. This allows the pilot to make informed decisions during flight. The system is especially critical for long-range, autonomous and commercial missions.

This kit provides two-way radio communication over long distances. It consists of two modules - an onboard transmitter and a ground receiver. The on-board module is connected to a flight controller (for example, Pixhawk). It collects data from sensors and sends it to the ground. The ground module receives the data and transmits it to the scheduler program on the computer.

• Long communication range to control the drone at a considerable distance.

• Two-way data exchange to transmit commands on board and receive telemetry.

• Compatible with popular autopilots Pixhawk, Cube and others.

• Reliable operation in noisy environments thanks to modern protocols.

• Easy integration and configuration through standard programs.

How does a radio telemetry channel work?

The on-board module receives data from the flight controller via a serial port. It encodes this data into packets and modulates the radio signal. The signal is transmitted at a frequency of 433 MHz or 915 MHz (depending on version). The ground module receives the radio signal, decodes it and transmits it to the computer. A planner program such as Mission Planner or QGroundControl displays the data.

The key is the two-way exchange. Not only do you receive information, but you can also send commands. For example, changing the target point in an offline mission. Or activate return home mode in case of video loss. This makes flying the drone much more flexible and safer.

Technical characteristics and capabilities of the system

The system uses a reliable data transfer protocol. Operating frequency 433 MHz or 915 MHz (selected when ordering). Maximum transmit power up to 1 W (adjustable). The range under ideal conditions can reach several kilometers. Supports data transfer rates up to 250 kbps. The onboard module is powered by the flight controller, and the ground module is powered by USB.

The functionality includes the transfer of all basic flight parameters. Current GPS coordinates, speed, altitude, heading (heading). Main battery voltage and current, RSSI signal level. Flight mode status, autopilot errors and warnings. Data transfer from additional payloads is also possible. For example, readings from a gas analyzer or cargo temperature.

This system is indispensable for serious flight tasks. When performing mapping missions to monitor area coverage. For inspection of extended objects such as power lines or pipelines. In search and rescue operations to coordinate with ground teams. Any flights where the drone goes beyond line of sight require telemetry.

Installation and configuration of the system are standard for such equipment. The onboard module is connected to the telemetry port of the flight controller. The antenna should be placed away from power wires and other transmitters. The ground module is connected to a laptop or tablet via a USB cable. In the scheduler, you need to select the correct COM port and speed.

The system is compatible with major software platforms. It works great with Mission Planner, QGroundControl, APM Planner. Real-time data transfer to the server via the Internet is supported. This allows multiple operators to monitor the mission remotely. The reliability of the connection has been tested by thousands of users around the world.
