U-Ground OneBoard User Manual - General System Introduction 1 General System Introduction Airelectronics has developed a complete solution for both rotary and fixed wing UAVs. The system is composed of: • U-Pilot 0.2 • U-Ground 0.2 or U-Ground OneBoard • U-See 0.2 U-Pilot takes care of the vehicle from Take-off to Landing. It is completely adaptable to any aircraft including fixed wing, hexacopters, quadcopters and helicopters.
U-Ground OneBoard User Manual - General System Introduction All the U-Pilot configuration is done by Airelectronics staff so the End User does not have to waste any time setting the internal parameters of the system. 1.1 Concept of system operation The system is made up of an U-Pilot installed on an aircraft connected to the U-Ground through a radio link. (See figure 1 attached below) The U-Ground has its own radio link to communicate with the U-Pilot.
U-Ground OneBoard User Manual - U-Ground OneBoard 2 U-Ground OneBoard The U-Ground OneBoard hardware is the link between our U-Pilot and the computer running USee that finally controls the mission. U-Ground OneBoard has an integrated GPS to track its own position and standard PWM outputs to allow the steering of directional antennas towards the UAV to maintain a stable video link.

U-Ground OneBoard User Manual - Communications 3 Communications Communication between the U-Pilot and the U-Ground OneBoard is done by a Radio Link with High noise immunity, high reliability and a range of 100 km. All the settings regarding the radio configuration is done by Airelectronics when the units are produced, so you do not have to worry about the communications, it is completely plug and play. Available on the bands of 2,4 GHz, 1,4 Ghz, 900 MHz , 455 MHz and 869 MHz with channel hopping.
U-Ground OneBoard User Manual - Alarms 4 Alarms When comunicated with an U-Pilot, the OneBoard Ground Station will decode the downlink communications and present basic information through the activation of the Alarms lines. These lines are designed to give a 3.3V TTL signal of high when the alarm is active and low when the signal is not toggled. The maximum signal strength the U-Ground is capable of driving is 25 mA. Typical use of these signal is the usage of LEDs or other kind of visual aids.
U-Ground OneBoard User Manual - Alarms The audible tone generated at current revision are 3 beeps of half a second duration and variable pitch in function of the toggled alarm. An audible tone will be generated any time an alarms toggles from deactivated to active. If more than one alarm is triggered at the same time, the ground station will generate tones for every one of the alarms in a sequential manner.
U-Ground OneBoard User Manual - Joystick 5 Joystick The Joystick used on this system is manufactured by Futaba. The model we use for development and our operation is the T7CAP, but any compatible Futaba Micro Plug Joystick can be used. The pin connection to the ground Hardware is detailed on U-Ground OneBoard Connections. The frequency modules (known as crystals) must be removed from the Joystick as the communications go through the Airelectronics radio link.

U-Ground OneBoard User Manual - Joystick Open Basic menu, then open PARAMETER. for 1 second. (If ADVANCE, again.) or to PARAMETER Go to MODUL and change setting. to MODUL to PCM. PCM flashes on screen Close menu and cycle power. Power Off. Power On. For the rest of settings, please, check the manual of the joystick. Please, check with the software (U-See) that the joystick sticks movement correspond to the following figure (In U-See, View → Joystick ).
