Uvitech has developed a complete solution for both rotary and fixed wing UAVs. Automatic control systems for unmanned systems have been developed and implemented with our participation, that allow to fly completely in automatic mode, to capture, process from various sensors and signal sensors and transmit them for a considerable distance over a digital protected channel. ACS is miniaturized high reliability avionics system of unmanned system. The unique ACS ads fully autonomous control capabilities to any unmanned system for complete operation, manages and controls the vehicle from Take-off to Landing. Once the flight plan is loaded on ACS, it is independent of operator instructions, and in case of a communications failure, it finishes the mission and starts a Return Home and Land on the safe land. The aircraft can be real time controlled by an operator or automatically.
Autopilots manufactured by Uvitech are capable of controlling every part of the flight envelope from just after take-off to landing. They are integrated with the flight management system (FMS) and, when fitted, the autothrottle system.
Autopilot software, which is integrated with the navigation systems, is capable of providing control of the aircraft throughout each phase of flight. If an autothrottle/autothrust system is installed, the appropriate thrust may be automatically set during take-off, and is then adjusted automatically as the climb progresses, while the aircraft climbs at the appropriate speed for its mass and ambient conditions. The aircraft then levels at the required altitude or flight level while the power is adjusted to achieve and maintain the programmed speed. At the same time, the aircraft follows the flight plan route. If an autothrottle is not installed, the pilot must make all power adjustments appropriate to the autopilot mode and phase of flight.
On commencing the descent, the power is adjusted and the aircraft descends at the appropriate speed and on the required routing, leveling as required in accordance with the flight clearance until the approach is commenced. On some aircraft, the autopilot can then guide the aircraft so that it maintains the runway centre-line until it stops.
At any stage of the flight, the pilot can intervene by making appropriate inputs to the autopilot or the FMS. In an emergency, the pilot can disengage the autopilot and take over manual control, usually by pressing a switch mounted conveniently on the control column (although alternative means of disengaging the autopilot are available). Modern aircraft have another switch or throttle position which allows the pilot to change instantly from approach to go-around mode if necessary. If the aircraft is not fitted with an automatic go-around function, pilots must disconnect the autopilot and fly the missed approach manually.
The safe and efficient operation of automatic systems relies on clear understanding of the capabilities and the design philosophy of the equipment.
These systems contain an onboard computer and aero navigation system that allows to perform a series of flight modes, while observing the high accuracy of positioning the device. In addition, this system allows to fly in conditions of the absence of any navigation signals (GPS). The capabilities of these systems allow processing a large data stream directly on aircraft board and the implementation of additional functions, such as precise definition of objects, capture and tracking of stationary and mobile objects, their recognition and identification. Obtaining information, processing and transmission on a reliable channel to a ground station, forming a powerful and reliable communication channel, allowing to operate at a distance from the ground station more than 120 000 feet. The systems developed with our participation also allows to organize the transmission of data at a considerable distance using our modules as signal repeaters, and in combination with the use of our developed sensors this system is a complete functional product for performing a huge number of tasks.
The entire system is designed to meet the requirements for aviation equipment, namely strength, class security, weight, dimensions and compliance with international standards. Our company participates in consulting and service for our customers.
The systems are designed and manufactured following the strictest safety and quality standards. All autopilots accomplishes DO-178C / ED-12 and DO-254 regulations.
