Does your autopilot use the PX4 flight stack?

FIXAR represents an all-in-one UAV solution with its own hardware and proprietary software for the autopilot system.  We don’t use any open-sourced stacks, neither PX4, nor Mavlink.

Where are the components for FIXAR UAVs sourced from?

All design and manufacture is made in house, from the aircraft’s structural elements to the autopilot boards. Some performance parts (such as rotors or battery elements) are purchased from specialized third-party suppliers in order to provide the best quality and reliability.

Does FIXAR use a tilting rotors scheme?

All 4 rotors are mounted at a fixed angle on a frame that swings forwards and backward relative to the rest of the aircraft. Thus, the vector of the lifting force from the rotors lifts the aircraft and ensures its horizontal flight pattern. During cruise mode and in vertical take-off/landing mode, all rotors remain in effect and do not create drag during a flight. Moreover, in horizontal flight, not only the wing but also the rotors generate lift resulting in a 3 times increased power reserve in comparison with copters type UAV’s of the same weight.

What is FIXAR UAV made of?

The aircraft frame, wings, and elevator are made from composite materials, such as glass fiber, fiberglass plastic, carbon fiber composite. The main structure is made from epoxy-bonded Kevlar. All major components are protected according to the IP55 standard.

What data link frequencies are used for telemetry? Do FIXAR use an LTE/4G connection?

FIXAR units use radio frequency for telemetry 868 Mhz for Europe/ 900 MHz for USA and Canada. On request, it can be implemented any other connection interface, including LTE/4G option.

How many frequencies are available in the geodesic receivers used during the flight?

Single-frequency (L1) or dual-frequency (L1\L2) GPS surveyor’s receivers are used. Depending on the configuration.

What happens if during the flight the aircraft gets into the range of navigation signal jammers (silencers)?

The UAV uses a unique algorithm of behavior in such situations that is embedded in the FIXAR autopilot system. In the event of a signal loss, the aircraft will stop to perform the mission and will return to the home point (using Inertial Navigation System and barometric sensor to control altitude). After the signal is reestablished and stabilized, the operator is required to instruct the aircraft to land or to continue flying.

Can video be transmitted in flight? If yes, with which quality?

The video monitoring configuration of FIXAR 007 has an HD format video transmission feature. The range of real-time signal reception from the camera is up to 15 km (9.3 mi).

What type of batteries do you use?

Lithium-polymer and Lithium-ion batteries are used to power FIXAR aircraft.



How long does it take to charge a battery?

The battery of FIXAR 007 takes 40 to 90 minutes to charge, depending on the rate of discharge during flight. The charging current should not be lower than 14 A.

How to use battery efficiently?

Plan mission with the lowest possible number of turns – energy losses during this maneuver are up to 15%, so the fewer turns are put in the route, the more energy-efficient will be.

Consider the weather conditions. A strong wind will use the battery faster than flying in calm weather. On average, the difference during flights of identical missions in calm and with an average wind speed of 15 m/s is up to 35%.

Consider the power consumption of payload when calculating flight times. For example, a switched-on SONY A6000 camera uses about 5-7% of the total energy supply. Consumption will vary depending on image overlap settings and individual camera settings.

The fewer altitude differences, the more energy efficient is flight. When flying in mountainous areas, for example, flight performance can be improved by starting the mission from the top point of the route and landing at the bottom. In this case, the increase in energy efficiency can be up to 35%.
