A2 flight controller system

DJI A2 multi

- rotor stabilization controller system is a complete flight control system for
various multi

- rotor platforms. It has high performance antenna, low noise anti

- interference front

end RF design, accurate position and speed calculating, these combi ned features gives it advantage of higher accuracy performance, larger measuring range, and unique damping design, and calibration algorithms, and ultimately gives IMU the ability to provide stable output even in high vibration and large movement environme nts. The built

- in receiver system directly supports the popular transmitters, and it also supports a variety of external receivers.

The A2 utilizes built

- in 2.4 GHz Radio technology DESST (DJI Enhanced Spread Spectrum Technology) receiver which supports F utaba FASST series of transmitters. It has 16channels. Futaba transmitter allows use of the system without any external receiver, which has greatly simplified complexity of the system and improved the security of the remote control system.
Hovering accur acy in GPS mode is 0.5m (vertical) and 1.5 m (horizontal), wind resistance is up to 8m/s, and has operating temperature between

- 5 ∘ C and + 60 ∘ C.

The GPS receiver of the A2 GPS

- Compass Pro Module is equipped with a new high gain and high performance right

- handed circular polarized (RHCP) antenna, the low noise anti

interference front

- end RF design and the optimized localization algorithm, which provides the GPS Pro with stronger anti

- interference performance, a stronger ability to capture satellite signals and a more accurate position hold calculating ability.
A2 system has two reserved JR and SPEKTRUM satellite receiver ports, which support JR
and SPEKTRUM satellite receivers.
The A2 system has a dual CAN

- Bus design, which means that the system data throu ghput will be doubled and the extendibility is improved. At the same time, the important data and the

non

- critical data are assigned respectively on different CAN

- Bus ports, which greatly improves the system stability.
The A2 is equipped with a minimum of twelve output channels, users can easily use it to control an eight motors, and the other four channels can be used as a general output interface to control retractable landing gear, gimbal, or camera switch, etc.
With the new generation GPS Pro/Compass Module and the hardware upgraded IMU module, the A2 has an optimized inertial navigation algorithm, which ensures the system can get a more reliable and accurate position and attitude estimate. The aircraft which is equipped with A2 will have very good per formance in position hold even in a semi

- closed environment, such as between buildings, it also has excellent hovering performance. At the same time, with the optimized algorithm of inertial navigation and the algorithm of wind resistance, the Wind
Resista nce performance of A2 is also improved, and the multi

- rotor can have position and altitude locked accurately even in windy

.It supports three flight modes and intelligent switching between them. Available modes are GPS mode, Attitude mode, and manual mode

. The Flight controller can adjust automatically within the changing flight environment and intelligently switch between GPS Mode and Attitude Mode to make sure the flight is safe.
In order to prevent multi

- rotor UAS from crashing or other harmful consequ ences caused by low battery voltage, A2 has two levels of low voltage protection with selectable LED indications, Go Home and Landing functionality.
When signal is lost, the system will trigger failsafe, it is possible to choose either hovering or Auto
Go Home/Landing.
A2 controller also provides One

- motor

- fail

- protection function. This function means that when the aircraft is in attitude or GPS attitude mode, and one of the motors stops, the aircraft will retain good attitude and rotate around the frame a rm with the stopped motor. In this condition, the aircraft is still under control and returns home safely and highly reducing the risk of a crash.
A2 has a POI function: Point of Interest. When the GPS signal is good, it is possible to
record current position of the aircraft as a point of interest by a preset switch on the remote controller. The aircraft can achieve a circling flight around the point of interest with the nose pointing at the POI in an area of 5 meters to 500 meters radius, when the rol l command is given. This function is easy to set and simple to operate, it is suitable for all

- round shooting of a fixed scenic spot. The DJI S900 has extensive flight experience, especially by professional photographers and film makers, but it has also b een used in construction companies and security firms.

It was used by r elief workers in Ludian earthquake zone to address two of the greatest challenges

– identifying areas amidst the rubble areas to focus the search for survivors, and clearing roads for supplies to get to the disaster area. Aerial images captured by the team were used by rescuers t o clear a road from Guangming Village to Tiansheng Bridge by identifying the easiest points of clearance. The team has also worked in the epicenter area of Longtoushan, where most of the traditional buildings in the area collapsed. The dense rubble and veg etation have made ground surveying extremely difficult, so using aerial images has helped identify where relief teams can focus on searching for survivorsPrecision Hawk Lancaster

– listed under number 820

The eBee RTK U AS i s manu f ac tur e d b y SenseFly located in Lausanne, Switzerland.
The eBee RTK is fully autonomous survey grade mapping drone. It utilizes in

- flight processing of Real Time Kinematic (RTK) satellite navigation corrections from leading brands of base stations GNSS/RTK via its supplied eMotion flight control software and ground mo dem, in order to enhance the precision of position data from satellite based positioning systems. The RTK coordinate correction system receives via ground modem enable precise navigation and the storage of image meta

- data with RTK

- level accuracy without th e need for Ground Control Points (GCPs). The eBee takes a collection of high

- definition still images that are used later to generate maps and contour lines of the surveyed area.

The gro u nd c ontrol station consists of a P C c ompu t e r with eMotion flight planning and control software, 2.4 GHz remote control with range up to 1 km and 2.4 GHz ground modem
whi c h h a ve a ma x i m um d a ta link r a n g e o f 1.8 miles (3 km). Remote control provides an override capability that allows the operator to take manual actions during the flight (Go Home, Go Land, Hold, and Resume mission), and also suspend automated operations and take manual control of the aircraf t if emergent
circumstances should arise.The eBee has two options if it loses link/connection with ground control. As fully autonomous, this UAS can continue with planned flight and land at designated point, or it may immediately execute return to the la nding site (Home waypoint) sequence. These options are set during the flight planning. AerialZeus will always and without exemption use this option for immediate execution of Home waypoint sequence if the link/connection
with the UAS is lost

. In

- flight war nings for dangerous situations, such as low battery or strong wind, immediately triggers return to the Home waypoint sequence. If its ability to fly is severely compromised, such as loss of GPS/GLONASS signal or empty battery, the UAS will perform an

emerg ency landing.

In 2015 eBee was used in monitoring of water quality in small reservoirs in Thailand. It was used to close the temporal gap between satellite imaging and in situ sampling ow water in reservoir. In addition, spatial resolution provided by satellite with multispectral s ensor wasn’t high enough for reservoirs which cover several hectares. It was concluded that fine temporal resolution and mobility of this UAS demonstrated that they could effectively preclude the weather from harming aerial imaging, and compared with tradi tional techniques of photogrammetry or satellite remote sensing, UAS offer better ratio between cost and profit in the trophic state mapping of reservoirs.
In November of 2014, a team of researchers from the Climate Change research Centre was
on three

- wee k expedition on New Zealand’s Sub

- Antarctic Islands, a UNESCO World Heritage
Site. The team decided to use the eBee UAS because no other method of data collection could provide the imagery required in the limited time available. Traditional method of in si te sampling would take weeks, if not been completely impossible due to the impenetrable density of vegetation. Such remote locations, like Sub

- Antarctic regions, have poor satellite coverage, those images that do exist have relatively low resolution. Lands at images have spatial resolution of 30 meters while eBee provided images with 8.8 cm per pixel which allowed identification of smaller scale features. Additional benefit from using eBee was that since it was mapping of environmentally sensitive location, low noise levels produced by eBee was important in protectedareas that contain large bird population, which would have been big problem for standard manned
aircraft.
In Turkey, a geomatics engineering company has used the eBee to map a railway corridor
8 7 miles long and 1,968 feet wide with total survey area of more than 27,000 acres. They surveyed plains, hills, mountains, and urban areas. Mountain reach was exceptionally inaccessible for standard surveying equipment. The images gathered by the eBee were used to produce a whole range of useful data. They were able to produce point cloud with average grid of 20 cm/pixel. For a site of 100 hectares, classical techniques usually measure about 30, 000 points, while the eBee is able to measure about 25,000,000 points and thus give smooth terrain with much more detail. They concluded that the use of drone

- technology gives them benefits in precision, flexibility and cost efficiency because it only took them no more than 10 people to map in high detail 87 miles
of railroad.
In May 2015 McIntosh Perry Surveying Inc. collaborated with UKKO to conduct test eBee and its capability of low altitude aerial photography and compare accuracies of horizontal positions and vertical elevations against a topographic and site de tail survey completed by McIntosh Perry on the same property in 2014 using Trimble R8 base and rover RTK GPS units. Site is primarily consisted of farmland and is being considered for development. The test has shown that a terrain model created by aerial i maging using the eBee platform can successfully compete in accuracy with conventional ground topographic survey completed using RTK GNSS receivers, comprising a base and rover. The real benefit showed in time difference; while ground survey required 4 days
, aerial survey required only 1 hour, and amount of data gathered by eBee is much larger than those of ground survey. Ground survey collected 1,800 data points, selectively chosen by trained personnel, while the eBee collected 31,000,000 points. It is conc luded that surfaces generated by aerial survey can be relied on to provide accurate topography and site detail at all points on the surface, without the large amount of interpolation required to construct a terrain model based on
much more limited numbers of ground observationsSenseFly eXom

– listed under number 821

The SenseFly eXom is an intelligent multi

- rotor drone designed for close mapping and industrial inspection applications. UAS eXom is manufactured by company SenseFly located in Lausanne, Switzerland.
System consists of lightweight battery operated aircraft with integrated sensors, ground control station and associated data link equipment. It is equipped with autopilot and GPS. The eXom is V shaped quadcopter with composite body, molded c arbon fiber arms and legs, precision molded magnesium frame, and precision molded injected plastic. Total dimensions with shroud are 22 in (width), 32 in (length), and 7 in (height). Its total max weight is 3.7 lbs and operates at low cruising speeds with max air speed in manual mode of 27 mph and in automatic mode 18 mph. It is powered with LiPo 8500 mAh smart battery that drives 4 electric motors, each with one propeller.
It is launched vertically from hand or small platform with flight duration limit of 22 minutes, with max climb rate of 7m/s, and low cruise speed with max air speed of 10m/s (automatic flight) or 12m/s (manual flight).
Ground station consists of PC computer with SenseFly eMotion X flight planning software
and control software with ScreenFly controller for assisted interactive missions, and remote control for manual flight. The eXom has operational safety features like signalization lights (navigation
and anti

- collision lights), ground proximity detection (Avoidance procedure through automatic stop, and warning signals), Flight assistance features (Cruise control, distance lock, obstacle avoidance), and automated fail safe behaviors such as Geofencing, Return home, emergency stop, emergency landing.
The eXom has digital, omnidirection al antennas, dual band, encrypted communication link, at 2.4 GHz and 5GHz ISM bands (country dependent), with range of up to 1.2 miles. Remote Control link uses frequency of 2.4 GHz with range of up to 800m.

It has five navcam sensors, and five ultrasound proximity sensors. Thanks to the situational awareness provided by this array of sensors the eXom can fly close to objects in order to achieve submillimeter GSDs (1mm GSD at 6m distance).This small, lightweight aircraft that operates at relatively slow sp eeds will pose little to no hazard to people or structures on the ground, thus making it an exponentially safer alternative to manned, fixed wing aircraft for aerial imaging.

The primary function of the eXom is to provide aerial imagery using one of two i ntegrated

geo

- reference cameras. Those cameras offer high resolution RAW still images, HD video and Thermal still images and video.

High resolution data generated from these cameras offer a wide range of applications through analysis, such as geo

- referen ced high resolution mapping, 2D orthomosaics, 3D building models, high resolution digital surface inspection of bridges, towers, rooftops, and cliff faces for cracks, construction monitoring, solar panels and wind turbines hot spot detections, conservation
, agricultural and environmental monitoring.

The eXom is hand launched on

- site, requiring no runway for take

- off and landing and no transit to and from the site. Once airborne, the eXom will fly at an altitude of 400 ft . AGL or less over the designated ob ject or area. Prior to flight, the Pilot in Command (PIC) sets a designated flight area and flight parameters to ensure that the eXom will remain within the confines of the approved site and not exceed a maximum altitude 400 ft . AGL. If a critical issue su ch as a low battery state or a loss of data

- link is detected at any time the eXom will immediately execute a

return

- to

- launch sequence. The eXom’s small operational footprint and built

- in safety protocol provide a much safer alternative for aerial imaging and would pose a minimal hazard to the NAS or public. In September 2015 two eXom were used for close mapping and inspection project during which gathered images that reached a global precision comparable to that of a total station survey. The site presente d a complex environment, with buildings, trees, and on

- site crane. Data was gathered with two drones for repeatable results.
Even flying in low

- light conditions, the eXom survey produced a 3D point cloud of millimeter accuracy, equivalent to the accuracy achievable using a total station.The eXom solution

— the drone and its two included software programs

— is therefore proved to be a high performance surveying instrument, capable of fitting into existing surveying workflows.
