The XLRSD1 system has a new fresh point of view, is up to 45% more economical than XLRS D2 but with almost all the benefits, because the system is scalable and can choose their functionality and final cost according to the licenses by software purchased.

It can work only as a radio modem, only as a radio control system or both at the same time. Also as a system of search and location of lost aircraft.

For the radio control system you will need to connect a standard RC Transmitter to the trainer port or a PC with Joysticks type GamePad.

The BTSD1 Ground Module, is powered by the USB, it will usually be connected to a PC or tablet.

In case of necessity or if it is used with powers of 1W, it can be fed externally from 4.2 to 5.6V. It can also be connected directly to a Lipo battery of 3V7 and 1A as a minimum.


For Radio Professional control of long range RC and telemetry from 25 to 200Km, according to licenses and models.

The radio control system is multiband and uses the free bands ICM (Industrial Scientific and Medical) of 866Mhz, 868Mhz (Europe), 903, 915Mhz (America) and 955Mhz (Japan).

RF quality. The radio frequency modules are the same as those used in the XLRS system.

To complete your equipment, you can use analog video or digital video at 2.4Ghz or 5.8Ghz or both simultaneously using different bands for each.



D1 is formed by the ground module BTSD1 and the vehicle module RXLRS. It is a very versatile system and with multiple possibilities that according to the licenses acquired can be:


1.- Radio modem.

With Mavlink protocol and transparent protocol.

On the ground connect the BTSD1 via USB to your PC or tablet. It is compatible with Mission Planner, QGroundControl, DMD_Studio, etc.

In the vehicle connect the RXLRS module to the TELEM port of the autopilot. It is compatible with Pixhawk, APM, etc.


2.- Radio Control System

Acquiring the license of radio control, besides radio modem you will be able to use XLRSD1 as radio control system, saving equipment, space and antennas.

a) With standard RC Transmitter:

Connect the trainer port of your standard RC Transmitter (radio control) to the SPPM input of the BTSD1 and will automatically detect the Joysticks and channels of the RC transmitter, sending them to the RXLRS receiver where will be activated the ports of 8 servos of which one of them can be series output of up to 13 SPPM servos to connect with the autopilot.

a) PC Joysticks:

Can connect to the PC via USB or if you are using the system as a radio modem via the RCBus port (you will need a BootADMD or serial converter).

The usb with a extension cord can have up to 25m, so you can install the module near the antennas so as not to have lost with the antenna cable and prepare a control base controlled with PC, Joysticks and personalized video.

c) Through a microcontroller (Arduino, Raspberry pi, etc.):

From USB to the RCBus port (you will need a BootADMD or a serial converter) with ACL commands.


3.- Search Terminal.

This utility will allow you to locate and find lost vehicles or aircraft using the RDB_RECOVERY radio beacons.

Very useful if you fly far or in complicated environments such as in the jungle, mountains, cornfields, etc. And and you have to make an emergency landing or suffer some mishap and lose his valuable dron or plane.



Compatible with XLRS D2, D3, D4 and XVID video systems.
All licenses can be used at once or separately.
