Unmanned aircraft system INDELA-SKY

Unmanned aircraft system INDELA-SKY is designed for standard monitoring tasks:

1. territory intelligence in real time, at any time of the day, in any climate, including severe weather conditions;

2. processing and transmission of the information in visual and infrared ranges;

3. record and transmission of television signal to the ground control station (GCS) at the distance up to 100 km within 5 hours of continuous flight;

Gyro-stabilized optical system INDELA OGD-20HIR.

The system INDELA OGD-20HIR is a basic payload for the UAV INDELA-I.N.SKY during the performance of standard intelligence, surveillance and monitoring tasks. The system INDELA OGD-20HIR is specially designed for the application with the UAV. Its features are as follows: four built-in modules (thermal imaging device, color camera, laser range finder, and inertial module), compact, light and robust body, active two-axis stabilization.

Video processor provides target tracking function and it can process video signals, received simultaneously from the thermal imaging device and color camera.

The function “picture-in-picture” allows displaying images on the monitor simultaneously from two video channels. The user can select and switch signal sources for “full screen” and “window” displaying.

In tracking mode the target is identified by the frame on the monitor display. The user can select one of several targets, specified by the tracking device.

Ground control station INDELA-GCS:

Ground control station INDELA-GCS is designed for remote control of the UAV, its equipment, and also for receiving and representing information from the payload on the monitors. GCS supports different working modes in the network and can be switched in any operating network or integrated into the existing network system.

GCS provides::

• Telemetry information exchange with the UAV in real time;

• Payload control;

• Reception, representation, recording, storage and reproduction of the information from the payload on the monitor displays in real time;

• Control of flight modes and payload operation;

• Planning and preparation of flight mission, its checking and loading into the board system;

• Control of technical condition of the UAV board system;

Aircraft software has a developed multilevel architecture, the basic layer of which is fully automatic and autonomous systems that also cover aircraft hardware and software complex. The access to the basic software layer is supported by a set of user interfaces.

As a whole hardware and software complex INDELA SKY is a fully independent robotic system, for which a limited set of modes and control commands available for a human is anticipated.

Flight control software allows to:

• Lay the route of the automatic flight of various configuration with more than 2000 intermediate way points;

• Automatically diagnose the UAV and control more than 200 UAV parameters and ambient parameters during the flight;

• Perform fully automatic functions of the UAV piloting;

• Perform fully automatically: takeoff, landing, en-route flight, and return to the start point;

• Program the flight route directly before its start, save it and load from the route library, and adjust during the flight;

• Adjust during the flight its main conditions, including the change of the height, speed and hovering time in any route point;

• Remotely control the aircraft.


UAV control workplace

The control of complicated software of a high-tech aircraft is performed easy and instinctively with the use of operator interface. UAV position, image from its course camera, as well as the most important information about the aircraft status is displayed on the workplace monitors. Interface arrangement is based on the aviation practice of using Graphic User Interface (GUI).

Payload control means

Payload operator workplace allows for the operator to view, record video information and switch between its streams. Video streams and collected data are saved for later reproduction or processing. Payload control is independent from the UAV and allows for the operator to fulfill all scope of the necessary operations regardless of the current operating modes of the aircraft.

Besides own operating modes the access to the most important information about the UAV flight is anticipated for the payload operator workplace: flight mission route, position on the map, current coordinates, statuses, etc.

The interface and architecture of the payload operator workplace anticipate the possibility to expand functions and application of the payload, and to use as a payload the products of third party manufacturers.
