FLIR Boson performances

ANAFI USA carries a 9 Hz FLIR Boson micro-bolometer. This module is equipped with a mechanical shutter which enables automatic recalibration of the sensor as often as possible, for a complete consistence of each thermal pixel’s response. The lens of the FLIR Boson has a 50° HFOV.

 

Coloring modes

ANAFI USA’s thermographic camera presents two complementary coloring modes, which enables the drone to adapt to every mission.

 

Relative mode

The relative mode displays a general view of the thermographic of a scene, on a colored scale, graduated from 0 (dark blue) to 100 (bright yellow).

Spot mode

Only coldest or hottest spots of the image are colorized, depending on the user’s needs.

Thermal analyzer mode

The Thermal analyzer feature of FreeFlight 6 USA provides you with a great tool to achieve quick thermal analysis, directly from your device.

This function gives you full control over the on-screen rendering of any thermography video or photo you have taken with ANAFI USA. From the analyzer, you can:

• access Thermal Preferences directly from the preview’s Preferences icon, top right;
• navigate inside your thermography videos;
• modify the thermography modes (Relative, hot and cold spots) and their associated thresholds at any point of any video or on any photo;
• modify the blending between Visible and Thermal spectrums;
• save as many screenshots as you want.

The photo displays or the video plays in Analyzer mode. As shown on the following screen captures (extracted from a video analysis), the interface gives you access to most options available for filming.

IR/Visible blending

To compensate the lower resolution of the thermographic image, by comparison with the visible image, and to add information that are not available through the thermal spectrum, ANAFI USA displays a fusion of the information of the two cameras. The data of the visible image is injected in the outcome footage, by luminance and to highlight the scene’s contours.

The fusion of images consists in:

• acquisition of visible image;
• acquisition of thermographic data;
• reprojection of thermographic data;
• colorization of thermographic image;
• extraction of visible images contours;
• mixing.

Zero no fly zone limitation

Conception

Key characteristics

• Ultra-lightweight: 500 g
• Folded (252x104x84 mm), ANAFI USA is ultraportable
• Functions in IP53 conditions for at least 32 minutes, a full battery flight
• No NFZ (no fly zone)

Compactness

Compact and lightweight, ANAFI USA weighs 500 g for a 1.7-liter volume. ANAFI USA can be transported in a backpack or a case.

Propeller replacement requires no tool: they just screw in the direction opposite to that of the rotation of motors, without risk of losing small mobile parts.

 

Ruggedness

The mechanical structure of ANAFI USA is mainly made of polyamid, reinforced with carbon fiber and streamlined using hollow glass beads.

ANAFI USA motors are protected from dust, sand and rain by lateral vent-equipped covers, that enable the dispelling of heat.

ANAFI USA’s vertical camera and ultrasonar are protected from the rain by a collar which shelters both sensors.

ANAFI USA has passed the following tests:

• IPX3 (CEI 60529 norm): Rain resistant in IPX3 (10 liters/min) for the time of one battery charge (32 minutes) at least.
• IP5X: Dust resistant for at least 32 minutes (CEI 60529).
• Damp heat (+40 °C and 93 % hygrometry) for 16 h (NF EN 60068-2-78)
• Dry heat (+50 °C) for 16h (NF EN 60068-2-2)
• Thermal shock: 20 1-hour cycles at -36 °C and +43 °C (NF EN 60068-2-14)
• Extreme temperatures: -20 °C and +70 °C for 4 h (NF EN 60068-2-1 & NF EN 60068-2-2)
• Low temperatures: -36 °C for 16 h (NF EN 60068-2-1)
• 92 flight continuous flight hours at ambient temperature, without mechanical wear
• ANAFI USA is functional after 18 falls (3 on each side) on concrete, from 1 meter high

 

Aerodynamics

Propulsion system

• The blades of ANAFI USA’s propellers have been conceived by biomimicry: they are inspired by the knobs of the anterior edge of the pectoral fins of humpback whales.
• Each propeller, consisting in two blades, is simply screwed on.
• From a flight perspective, ANAFI USA outperforms drones which are 1.5 times heavier and twice as cumbersome.

The advantages of “humpback whale blades”

1. The conception of the blade minimizes the transitory separation of the boundary-layer for each blade, to:

• recover thrust at constant motor rotation speed (rpm) – or alternatively to keep thrust while lowering the motor speed;
• minimize the sensitivity of the raising of mechanical power when blades twist.

Therefore, with a lower rotation speed for a higher engine torque, ANAFI USA emulates a rotor whose power is higher than the theoretical capacity of its diameter.

2. The tonal sound power of the anterior edge of the blade, is minimized, lowering the noise of the flight.

• ANAFI USA motors are powerful (46 W) with a 70 % yield (mechanical power divided by electrical power) when hovering; they have been conceived to optimize the blades’ characteristics on the whole flight range.
• ANAFI USA has the best weight/flight time ratio of the industry: its 32 minutes flight time, its low weight (500 g) and the high yield of its conversion chain enable the drone to fly fast (54 km/h) and far (theoretical outreach: 17,4 km at 40,6 km/h).
• Wind resistance: 54 km/h
• Sound power level at 1 m (3 ft): 84 dB

Fly by coordinates (Cursor on Target)

ANAFI USA features a fly-by-coordinates function which allows you to instantly display, reuse and share any coordinates in the surroundings of your drone – or indeed the GPS position of your drone itself. This is especially useful to precisely locate any point of interest or person ANAFI USA has detected.

 

Quality

• Parrot is ISO9001 certified.
• Every drone is controlled on a production bench (FVT).
• Bench #2: IMU thermal calibration plus barometer and magnetometer test.
• Bench #3: IMU & magnetometer dynamic calibration.
• Bench #4: motor disturbance measure on the magnetometer.
• Bench #5: ultrasound test.
• Flight test: every drone performs a flight test at the end of the production process: take-off, hovering, landing.

Numerous durability tests are performed during our development cycles. These take the form of a quest for the optimal drone size.

A drone you can trust

Security

ANAFI USA protects the data stored on the drone or sent through the networks and protects the drone against malicious software modification attempts.

Integrity of the software and protection of the drone

ANAFI USA’s software is digitally signed, which ensures that each update comes from Parrot and has not been modified.

The access to ANAFI USA’s operating system is protected. The drone has no local nor remote access to its embedded system.

Network connections security

The network links between the drone and its controller are authenticated and cyphered with a WPA2 protection (802.11i standard). WPA2 is based on an AES CCMP encryption, including a 128 bits encryption key. AES CCMP includes a CBC-MAC mechanism which ensures the authentication and the integrity of the network’s links.

A unique encryption key is generated for each drone/controller couple. In addition, users can define their own key.

802.11 protected management frames is activated to prevent disassociation attacks, which could cause denial of service.

SD card encryption

Full disk encryption of the SD card protects the confidentiality of data stored on the drone, even if it is captured by an adverse party.

Once the encryption is activated, the videos and photos are stored in a LUKS2 volume encrypted with AES-XTS and a 512 bits key. The use of a unique identifier for each container enables the management of a fleet of SD cards which can be used on several drones.

Once the SD card is encrypted, it can never be accessed without the encryption key. The passphrase is carried by FreeFlight 6 USA and is never stored permanently on the drone, which protects from forensics analysis.
