        State-of-the-Art Motors
The compact brushless motors we use are minimum-wear and provide high performance and a long service life. We use our own test stand to determine the efficiency of different motor/propeller combinations.
 
        Next-Generation Brushless Motor Controller
We have designed our own high power brushless motor controllers – they can provide 1 kilowatt of power to each motor. When the controllers need to slow a motor down, they use active braking to recovery electrical power, feeding it back to the flight battery, making for longer flight times. The controllers write their status, temperature, and the electrical current being provided to the motor to a log file. Any overload or motor failure status is immediately downlinked to the pilot on the ground. A redundant data bus provides additional safety margin.
 
        Advanced 32-bit ARM and AVR Central Processors
Depending on the number of motors, from 12 to 15 single chip microcomputers are used for flight control, navigation, motor controls, GPS, camera interface and other functions. The computer source code for these microcontrollers is Open Source, written in C, and can be modified by our customers if required.

 
        Open Interface
The serial protocol for controlling and configurating the MikroKopter is open and documented. Control the Copter with your own firmware via wireless telemetry intercace or an own controller on board.

 
        Cutting Edge Nanoscale Sensors
We use the state-of-the-art nanotechnology sensors for solid-state gyroscopes and accelerometers to measure the attitude and movement of the copter. A 3D Hall Sensor compass reads the Earth’s magnetic field to help with navigation. A highly sensitive pressure sensor, combined with the accelerometer data provide a “height hold” and allows for automatic take-off and landing.
 
        Advanced Global Positioning System
The GPS board uses the most recent, highly-sensitive GPS antenna and preamplifier with a SAW frequency filter that can get a 3D position lock with a limited sky view or when satellites are shielded by terrain and buildings. This system can get positional data from the U.S. GPS, the Russian GLONASS, and the Chinese BeiDou satellites.
 
        Telemetry via Personal Computer or Tablet
MikroKopter’s copters have a bidirectional telemetry system with a range of up to 6 Km and operating at different frequencies (2,4Ghz, 868Mhz, or 900Mhz) display copter position and operating parameters on a PC or tablet. These parameters include the copter’s height, flight battery voltage, elapsed flight time, motor currents and more. This telemetry data can be integrated with Google Earth for navigation or stored for offline use and integration with your own map data.
 
        Voice Announcements and Logging of Telemetry Data
For certain RC Transmitters such as JETI or the Graupner HoTT the transmitter can speak flight critical information out loud. This includes flight battery voltage, height, distance, mode changes, and errors. These voice announcements can be made predetermined time intervals or in response to a control switch on the RC transmitter. This telemetry data can also be logged in the RC transmitter – for example, the last GPS position in the case of a crash or loss of contact with the copter.
 
        Safe and Easy Flight Operations
Flying a Mikrokopter multi-rotor copter is safe and easy because we have such features as Come Home (which brings the copter home at a preset altitude), CareFree Mode (which allows beginners to fly without worrying about control reversal), Automatic take-off and landing to make learning to fly safer, Failsafe (which brings the copter home on loss of contact with the RC transmitter) and Geo-fencing (which confines the copter to specific territory).
 
        Free Mikrokopter Software
Mikrokopter provides free software updates for new features for the Flight Controller, Navigation Controller, GPS board, and the Brushless Controllers. You also get the free Configuration program, Mikrokopter Tool (for Windows PCs), an Android tablet based flight planning tool, MKTT, for setting up waypoints, and geo-fencing. We also provide a free flight simulator, AeroSimRC (the software is free, but you need to purchase a USB dongle), so that you can learn to fly a copter without expensive crashes and whatever the weather is doing outside. Finally, we also provide a free flight time calculator so you can predict your flight times, and a special tool for reviewing the GPX flight data logs created by the Navigation Control board.
 
        Source code
Mikrokopter makes is source code available under an Open Source licenses so you can easily tailor it to your needs. Note: to compile the Navigation Control board source code you need our Lib-Link license.
 
       

Long Distance Waypoint Flying
Mikrokopter permits waypoint flying up to 250 meters from the take-off point. If you need to pre-program more distant waypoints, all you need do is purchase an extended range license and copy the license file on to the microSD card in the Navigation Control Board.
 

       

Easy Maintenance and Simple Modular Design
The Mikrokopter multi-rotor copters are easy to maintain and repair. They use interchangeable parts that are easy to replace without coming back to the workshop.
