Parrot ANAFI USA

ANAFI USA, produced in the United States, presents top-notch security, resilience, and imaging capabilities comparable to Parrot's Short-Range Reconnaissance (SRR) drone specifically crafted for the US Army. With ANAFI USA, you can expect exceptional privacy and security for sensitive operations, as its data encryption and privacy functions align with the European Union's General Data Protection Regulation (GDPR), ensuring industry-leading privacy and security measures.

Design

ANAFI USA, with its compact and lightweight design, weighs 500 g and occupies a mere 1.7-liter volume. This makes it conveniently portable, fitting easily into a backpack or case for transportation.

ANAFI USA stands out as the smallest drone in its category within the enterprise and military sectors. It can be unfolded and ready for flight in just 3 seconds. Unlike fixed pitch propellers, ANAFI USA employs a propeller blades system that minimizes its bulkiness.

Replacing the propellers is a hassle-free process as no tools are required. Simply screw them in the opposite direction of the motor rotation, eliminating any risk of losing small movable components.

ANAFI USA incorporates a mechanical structure primarily constructed from polyamide, reinforced with carbon fiber, and streamlined using hollow glass beads.

To safeguard the motors from dust, sand, and rain, ANAFI USA is equipped with lateral vent-covered shields. These covers facilitate the dispersion of heat while providing protection.

Furthermore, ANAFI USA features a collar that shelters both the vertical camera and ultrasonic sensors from rain, ensuring their functionality even in inclement weather conditions.

Resilience

ANAFI USA has successfully undergone the following tests:

Propulsion System

ANAFI USA's propeller blades draw inspiration from the knobs found on the leading edge of humpback whale's pectoral fins, employing biomimicry in their design. Each propeller is composed of two blades and can be easily attached by screwing them on. In terms of flight performance, ANAFI USA surpasses drones that are 1.5 times heavier and twice as bulky, offering superior maneuverability and agility.

ANAFI USA incorporates a blade design that focuses on minimizing the transitory separation of the boundary layer for each blade, serving two primary purposes. Firstly, it allows for the recovery of thrust while maintaining a constant motor rotation speed (rpm), or alternatively, enables the drone to sustain thrust while reducing the motor speed. Secondly, it helps reduce the impact of blade twisting on the increase in mechanical power. As a result of this design, ANAFI USA effectively emulates a rotor system that generates power surpassing the theoretical capacity of its diameter, achieved by operating at lower rotation speeds with higher engine torque.

Furthermore, the leading edge of the blade is designed to minimize the tonal sound power, resulting in a reduction in flight noise. ANAFI USA features powerful motors, rated at 46 W, with a 70% efficiency (mechanical power divided by electrical power) during hovering. The overall characteristics of the blades are optimized to deliver optimal performance throughout the entire flight range.

ANAFI USA boasts the industry's best weight-to-flight time ratio, offering an impressive 32 minutes of flight time. With its lightweight design (500 g) and efficient conversion chain, the drone can fly swiftly, reaching speeds of up to 54 km/h, and cover considerable distances, with a theoretical outreach of 17.4 km at 40.6 km/h. It exhibits wind resistance up to 54 km/h and produces a sound power level of 84 dB at a distance of 1 meter (3 feet).

Cybersecurity | Data Integrity | Encryption

Security measures implemented in ANAFI USA focus on protecting data, ensuring software integrity, securing network connections, encrypting SD card data, and providing control over data management. Here are the key points:

• Data Protection: ANAFI USA safeguards stored and transmitted data, defending against unauthorized access and malicious software modifications.

• Software Integrity: The drone's software is digitally signed, guaranteeing that updates originate from Parrot and have not been tampered with.

• Operating System Protection: ANAFI USA's operating system is securely protected, preventing both local and remote access to the embedded system.

• Network Security: Network connections between the drone and its controller are authenticated and encrypted using WPA2 (802.11i standard), utilizing AES CCMP encryption with a 128-bit key. The network also employs a CBC-MAC mechanism to ensure authentication and link integrity.

• Unique Encryption Keys: Each drone/controller pair is assigned a unique encryption key. Users also have the option to define their own key.

• Protection against Disassociation Attacks: ANAFI USA activates 802.11 protected management frames to prevent disassociation attacks, which can cause denial of service.

• SD Card Encryption: The drone implements full disk encryption for the SD card, ensuring the confidentiality of stored data even if the card is compromised. Encrypted videos and photos are stored in a LUKS2 volume encrypted with AES-XTS using a 512-bit key. Unique identifiers for each container enable SD cards to be used across multiple drones.

• Secure Passphrase Handling: Once encrypted, the SD card can only be accessed with the encryption key. The passphrase is carried by FreeFlight 6 USA and is never permanently stored on the drone, providing protection against forensic analysis.

• Data Management: By default, ANAFI USA, the controller, and FreeFlight 6 USA do not share data with Parrot or any third party. Users have the choice to activate data sharing, which includes flight logs, to facilitate support and contribute to product and service improvements. Sharing data anonymously or linking it to a Parrot account requires explicit user activation, which is deactivated by default.

Optical Unit Manufacturing: Active Alignment:
The assembly of ANAFI USA's optical unit and sensor utilizes an active alignment technique. A robotic arm precisely positions and holds the optical block in place, achieving optimal performance in various aspects:

Ensuring desired focus at a set temperature (23 °C +/- 2 °C) and maintaining resolution specifications across the scene.
Positioning the optical block to maintain uniform resolution in yaw, roll, and pitch, especially at the image edges.
Aligning the sensor with the optical block axis for optimal performance at the center of the image.
Aligning the optical center with the sensor center within a tolerance of +/- 20 pixels or 22 micrometers.
To guarantee image quality specifications, the factory performs image calibration on each optical unit. The optical unit's internal memory stores essential information such as optical center, dead pixel mapping, lens shading mapping (luminance and color), and white balance, ensuring consistent and accurate image quality.

Thermal Camera

The FLIR Boson micro-bolometer integrated into ANAFI USA operates at a refresh rate of 60 Hz. It is equipped with a mechanical shutter that automatically recalibrates the sensor to ensure consistent responses from each thermal pixel. The lens of the FLIR Boson provides a horizontal field of view (HFOV) of 50°.

ANAFI USA's thermographic camera offers two complementary coloring modes, allowing the drone to adapt to various mission requirements.

Relative Mode

In the relative mode, the thermographic camera displays a comprehensive view of the scene using a colored scale. The colors range from dark blue (representing lower temperatures) to bright yellow (indicating higher temperatures). The relative mode provides a visual representation of the thermal distribution within the scene.
