The 3DR Radio is the easiest way to setup a telemetry connection between your flight controller and a ground station. As the platform is open source, implementation can be purchased from many different sources, including ArduPilot Partners:. Privacy policy About Geeetech Wiki Disclaimers. The implementation of LBT in 3DR radio module due to using the lowest 5ms receiving time and the random receiving time is the same as the European 9. The latest version of the APM firmware can use this information to automatically match telemetry streaming rate to data rate maintained by the radio module.

The main features of the SiK Radio are listed below see the Advanced Configuration for more information:. Typical range achieved with the radios using standard configuration and antenna is around m, but the range varies a lot depending on noise sources and antenna setup.

The disadvantage of ECC option is that it 3dd halve the available bandwidth, but it’s worth it in the most situations, you can maintain the reliable links within a farther range. Regarding the power level, you must be very careful to deploy the radio module, and you should obey the legal authority limits of the country when operating.

Please pay attention to Plus-n-Minus of the power supply, the chip and circuit would be burned if connecting the power supply inversely. If you select a rate not supported, the program will choose the next highest rate supported. The other factor to select the data transfer rate is TDM “synchronization time”. The radios have slightly different form factors and connections v2 comes with a built-in FTDI cable but otherwise their behaviour is very similar.


3DR Radio v1 — Copter documentation

The radio module firmware supports MAVLink 0. The principle is to change receive channel slowly while rapidly change the transmission channel. Two radio need to compute mutually the frequency hopping pattern.

The ground based radio was attached to a 3. The meanings of the LED’s different telenetry are as follows:.

As the platform is open source, implementation can be purchased from many different sources, including ArduPilot Partners: Radio module will record this parameter and then convert it to the signal intensity, which means that the channel is occupied. On a windows 7 or higher machine, the require drivers should be automatically installed the first time you plug in the ground module but if it does not install for some reason or the ground computer is running Windows XP or earlier you can get the D2XX FTDI driver here.

Although anecdotal, another user provided a Tlog showing a good link kept while the vehicle was 4. The radio has interchangeable air and ground modules, meaning that you use them as a pair but it does not matter which one goes on the vehicle and which remains on the ground.

First of all, it needs net Framework 4. The radio uses open source firmware which has been specially designed to work well with MAVLink packets and to be integrated with the Mission Planner, Copter, Rover and Plane.

These radio modules support only 13 kinds of air data transfer rate, including 2, 4, 8, 16, 19, 24, 32, 48, 64, 96,and Note You cannot connect via the radios when your APM 2. Views Read View source View history.


Setup the two radios one meter apart and look at the local and remote RSSI. The following sections explain how to connect these to flight controllers and ground telemerty.

D3r can only support the power levels in the table below. LBT is a system whose radio modules needs to be monitored for a period of time to see if there are other radio module signals, and then be allowed to transfer. The connections required are shown below.

To connect the radios: All our products have been tested rigorously before shipping, bootloader and firmware have been burned, and the corresponding parameters have 3dt configured,they can be put into use directly. A SiK Telemetry Radio is one of the easiest ways to setup a telemetry connection between your Flight Controller and a ground station.

It provides a significantly better range. If you open the ECC strongly recommendedthe transfer rate will be cut in half, but it is worth it, error rate will drop sharply, a more reliable telemtery can be received within a farther range. Telemetry Radio Regional Regulations. This article only covers the main difference between the two radios — connecting the radios. The radios have 2 status LEDs, one red and one green.
