Based on the proven Mk09 aerial mapping UAV, in collaboration with the Spatial Data and Visualization Lab at the University of Hawaii at Hilo, this system 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.
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.
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.
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.
The Headwall uses a dedicated GPS antenna for geo-location of collected 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 interference from the aircrafts electrical system.
Navigation & Communication Systems
Communication system consists of double redundant command and control links.
- RFD900 Long range telemetry radio features frequency hopping spread spectrum, >40km depending on antennas and ground control setup, and automatic antenna diversity switching in real time to avoid loss of radio contact.
- Futaba T8J 2.4 ghz command link
20 Ah battery supply allows for 15-17 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.
"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
When not in use or transporting on site, the payload bay is protected by a quick release cover that also serves to support the sensors mounting structure.
To protect the lens form dust contamination during takeoff and landing procedures, the sensor can be fully retracted into the body of the aircraft.
Portability & Transport Protection
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.
