At the HAPS4ESA 2019 conference Aliaksei Stratsilatau, UAVOS Chairman of the Board and lead developer, spoke about the UAVOS's solutions in developing the High Altitude Pseudo-Satellites (HAPS) as exemplified by the UAVOS ApusDuo project.
With over 200 participants, the HAPS4ESA 2019 was the meeting bringing together HAPS system, payload and applications developers, space agencies and scientists. Aliaksei Stratsilatau gave the presentation "Solar Flight Technology (HAPS) Atmospheric Satellite «Apus-ApusDuo».
1. Presented solution for HAPS that allows to implement a large wing elongation for an aircraft with a large span based on the active control of the wing geometry and the aerodynamics of the apparatus, and not increasing the strength and rigidity of the structure controlled by the classical scheme.

Why UAVOS Inc. uses the unmanned helicopters by the aerial power line inspection instead of a quadcopters and airplanes?
Proposing aerial power line inspection using our helicopters and airplanes, we identified the following advantages of the helicopter scheme over airplanes and quadcopters:
1. The helicopter has high resistance to strong winds on takeoff and landing. For example, a wind of 14 meters per second is not an obstacle to perform work, while for a quadcopter it is a serious obstacle because of its low flight speed. An airplane landing with a parachute at such wind speed often causes damage to the apparatus and its payload.

The prospect of a flying taxi that lifts you over the traffic and speeds you to your destination is an enticing one. But some experts suggest that ambitions to introduce aerial taxis within three or four years are potentially achievable, if not necessarily affordable. Here is what Aliaksei Stratsilatau, UAVOS Cofounder and Lead developer, thinks about that issue.
The main obstacle in creating a legal and regulatory framework for flights of unmanned aerotaxi-like vehicles remains the unresolved issue of automating the process of a pre-flight UAV inspection without the participation of professional technicians. As a result, each flight of an unmanned vehicle has to be accompanied by a team of specialists - as in a case with a real manned aircraft. This is especially true for flights over the city, populated areas and industrial facilities.

How does the Automatic Control System for Moving Objects and Armaments work?
The significance of the Autopilot developed by UAVOS is the possibility of integrating the system into unmanned platforms of different operating environments with various mass-size characteristics.
The Automatic Control System is essentially an on-board computer with a proprietary software for automatic control of mobile objects, including a set of sensors: an inertial system, an air data system (ADS), a Global Navigation Satellite System (GNSS), a magnetic compass, etc. and actuation devices: servo-actuators, propellant charges, etc. The system configuration allows connecting to it ready-made third-party modules and entire systems in general.

The system of counteraction to GNSS spoofing attack is the result of many years of consistent work by UAVOS in the area of counter-EW.
The algorithms of radio electronic protection and automated control system by UAVOS provide effective counteraction to the most modern radio electronic interventions, depriving the enemy of the opportunity to take away from the route an unmanned aerial vehicle or to destabilize the operation of the on-board navigation system.

As experts in the field of automatic control systems and control algorithms, and thus robotic behavior, we believe it is too early to implement artificial intelligence into military systems.
Artificial intelligence (AI) is a strict set of algorithms. Implementing artificial intelligence is usually limited to video processing which can hardly be called artificial intelligence…even the term AI itself can be interpreted in many ways!

HAPS (High Altitude Pseudo Satellite) is an innovative project aimed towards the future and capable of changing not only the UAV market and the scope of UAV utilization, but also adjacent markets. This will open new horizons to companies involved in the production of equipment for stratospheric aircraft.
The potential implementation of solar-powered UAVs is widening. From geo-synchronous flights, to flights in the northern latitudes HAPS are taking on more and more practical tasks, pushing high-tech companies to develop new unique instruments and equipment, first as prototypes, and in the future – as mass production for stratospheric operations.

Currently we are witnessing a process of transition from manual control to fully automatic mode of vehicle and machinery operations. Automated systems are gradually replacing humans, and the reliability of technology is increasing. And we believe that the main reason of accidents is the human factor, although equipment failure is often the main cause of accidents for budgetary drones.
In today's unmanned aircrafts, it is impossible to single out the main problem leading to accidents, since in different segments the key reasons are different factors. For example, if we look at cheapest drones worth up to $4000, then we will immediately find out a whole bunch of problems affecting flight safety.

At the present time, the main and most effective means of combating small-sized UAVs equipped with MEMS-based avionics (micro electromechanical systems) of gyroscopes and accelerometers that are characterized by low cost and miniaturized dimensions, in contrast to high-precision fiber-optic PINS (platformless inertial navigation system) is using jamming countermeasures on the GNSS (satellite radio navigation signals GNSS).
Ordinarily, the vast majority of such small-sized UAVs after the loss of the GNSS signal lose orientation and fall, or make a forced parachute landing or automatic landing – as in case with multi-rotor UAV systems.

For more than 40 years, leading aircraft manufacturers have been working on the development of unmanned airplane-type aircraft capable of operating for a long time (from several days to several years) at altitudes of 60,000 - 100,000 feet (18,000-30,000 m).
UAVOS also has such experience. Our team has been working on a project to create HAPS Apus for more than 5 years. During this time we managed to build more than 20 modifications of the aircraft and successfully tested 3 new aerodynamic schemes of the aircraft.

To integrate the autopilot into various mobile platforms, both airborne and surface (above ground/water) based, ranging from 2.2 lb to 2626 lb (1 kg to 1200 kg), UAVOS engineers implemented the concept of a multi-platform modular design of the automatic control system for moving objects.
The main feature of the AP10 automatic control system is a distributed architecture, when each component of the system has its own microcontroller providing data processing and communication with other components within the CAN network (Controller Area Network). The AP10 configuration allows to avoid loading the central processor with routine tasks by distributing management tasks to all system components. At the same time there are efficiently no restrictions on the number of the same-type modules, which makes it possible to implement multiple redundancy on all levels. Almost any payload, or ready-made third-party modules and entire systems can be connected to the system by adding IFC interfaces to the network.
