ATMK09 Hyper-spectral
Based on the proven Mk09 aerial mapping UAV, in collaboration with the Spatial Data and Visualization Lab at the University of Hawaii at Hilo, the ATMK09-HS has been designed from the ground up to deliver the highest quality data while also providing a protected environment to safeguard the valuable, sensitive Headwall Nano-Hyperspec Sensor.
Advanced Aircraft Design
AeroTestra uses a proprietary design method similar to modern aircraft. Technically described as a "thin shell" or monocoque structure it carries both tensile and compression forces within the skin and can be recognized by the absence of a load carrying internal frame. This design allows for a very high strength to weight ratio. This allows for a large, protective internal area for payload capacity.
Image Stabilization
Sensor is stabilized in both axis with an ultra precise, brush-less gimbal correction mechanism.
Vibration isolation retains data integrity by decoupling the sensor from the aircraft's main fuselage with a proprietary structural design system.
Commercial Grade Propulsion System
Standard equipment on all AeroTestra multirotor platforms, KDE propulsion systems demonstrate the highest standard for performance and reliability available on the market. Designed with commercial applications in mind, they outperform all others and with regular maintenance will provide years of dependable service.
Using a collapsible propeller design means there is no assembly required to prepare for flight operations. Simply remove the vehicle from the case and the propellers automattically deploy once motors are initiated.
Navigation & Communication Systems
Communication system consists of double redundant command and control links.
RFD900 Long range telemetry radio features AES encryption and ~40km range depending on antennas and ground control setup. Automatic antenna diversity switching to avoid loss of radio contact.
Futaba T8J 2.4 ghz command link
Headwall INS-GPS
The Headwall uses a dedicated GPS antenna for ortho-rectification of scanned data required for post processing.
To achieve the highest possible accuracy the antenna is located directly above the sensor and a ground plane, just below the antenna, was designed to reduce the effect of electromagnetic interference from the aircraft’s electronics.
Power Supply
20 Ah battery supply allows for 16-18 minutes of actual flight time with ample reserve to ensure safe operating conditions. Batteries are exchanged in seconds due to the innovative battery attachment mechanism.
Our aircraft feature Mauch Power Supplies which utilize “hall effect” sensors for accurate power monitoring and minimal power fluctuations.
"Smart Battery" technology allows for monitoring vital conditions of battery system including charge state and sell balance with the touch of a button.
The advanced battery management system provides additional functionality that will increase the usable life of the battery including:
Self-balancing function
Self-discharge function at High Temperature storage
Over voltage and under voltage alert function
Over Temperature and low temperature alert function
Cell abnormal alert function
Portability & Transport Protection
No assembly or disassembly of the aircraft is required during normal operation. This reduces the risk of failure due to improperly installed components
All system components are contained in an indestructible, waterproof SKB mil-spec case. The case and all components weigh in at approximately 42.5 lbs, meeting TSA requirements for standard luggage size and weight.
Payload Protection
When not in use , the payload bay is protected by a quick release cover that both protects the sensors electronics and lens from contamination or damage as well as well as supporting the sensor’s precision stabilizing structure.
During take-off and landing procedures, the sensor can be retracted to protect the lens from dust contamination that may compromise data quality.
Sample of HYPER-SPECTRAL scan Data
Below is a sample of the scan data resulting from flight testing. Unlike normal image data, each “capture” is a single pixel in width, so camera stability is of vital importance. The raw data below demonstrates the performance of our precision sensor stabilization system.
