U-Ground User Manual - U-Ground

U-Ground

The U-Ground hardware is the link between our U-Pilot and the computer running U-See that

finally controls the mission.

U-Ground hardware relays the data it receives from the U-Pilot through a serial RS-232

interface. This data is processed in U-See running on a standard PC which should have a RS-

232 port available (We include a USB to RS-232 converter in the installation kit).

U-Ground 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.

It also provides the manual override function, by connecting any standard Futaba transmitter

with a trainer port to the hardware. In that way, an external pilot can fly the UAV in a manual

mode (Refer to section 5, joystick) with the very familiar interface of a Futaba joystick, while

keeping all its functionality (exponential settings in control, mixtures, etc.)

2.1

U-Ground and U-Ground OEM

U-Ground can be acquired in two versions, the standard version, enclosed in an aluminium box,

and the OEM version that is not enclosed, ready to be embedded into the customer system.

Unless told otherwise, the explanations provided by this document are valid for both versions.

When different explanations are required, this document will state it.

2.2

Power supply

U-Ground power supply accepts voltages in a range from 6.0V to 24V.

CAUTION: Powering U-Ground at a voltage OUT of range can cause IRREVERSIBLE DAMAGE to

the system. Please read carefully this manual and do not hesitate to contact us

(www.airelectronics.es) if needed.

Typical power consumption about 4 Watt, but the power system should be prepared to

withstand 7 Watts peaks. This consumption will mean an intensity consumption of 0.8 Amp. at

6V or 0.4 Amp. at 12 V.

U- Ground Main Connector

The aerial part of connector used for U-Ground is provided in the Installation Kit. Cables in the

aerial connector are colour coded. The following table describes the function of every pin in the

main connector in U-Ground and the corresponding colour coded cable in the supplied aerial

connector.
