KDE Direct Upgrades UAV Electronic Speed Controllers

KDE Direct recently announced new features for their UAS (unmanned aerial system) UVC electronic speed controller (ESC) series and KDE Device Manager V1.32 software. Upgrades include data logging and graphing, stall protection, and motor control optimizations. The new data graphing and logging features are accessible by updating the UVC Series ESC to the latest firmware. During a flight, the UVC Series ESC records the following:
  • Drive Voltage
  • Drive Current
  • Temperature
  • Motor Drive Power
  • Input Throttle
  • Output Throttle
  • RPM
  • Power Consumption
The new KDE Device Manager is customizable and has a new assortment of graphing features to view the ESC data log. The latest update also features a variety of display options, changeable units, and printing. The data log also offers a number of other intuitive features. Users can save data logs as well as upload a data log from a previous flight. Additionally, users can change the data log speed to allow the ESC to record more data. KDE have added the ability to record multiple flights and see all use time. This allows users to keep track of flights in a way that makes the most sense to accomplish their goals. All KDE ESC’s now have the option to turn on Stall Protection. This advanced algorithm allows for the immediate shutdown of electronics during propeller impact or alternate unsafe event. Stall protection also guards the ESC from damage and detects if a propeller is blocked. A number of motor control optimizations have also been added to the KDE Device Manager. The motor control algorithm on KDE’s ESCs have been optimized specifically to particular UAS Multi-Rotor Brushless Motors. This can be accomplished by selecting which motor is being used in the KDE Device Manager, and provides greater efficiency and overall improvements on the motor control.

VectorNav’s VN-200 Integrated into Precision Imaging Payload

VectorNav announced that its VN-200 GPS-aided inertial navigation system (INS) was selected for integration into Overwatch Imaging‘s TK-series precision imaging payload. The payload is for aerial smart mapping and automatic detection applications for UAVs (unmanned aerial vehicles) and manned aircraft.  

Soda straw effect

Traditional tactical imagery payloads, such as stabilized turret systems, feature electro-optical cameras with small field-of-view angles and high zoom capabilities. Such systems are ideal for tracking target objects from high altitudes; however, they suffer from the “soda straw effect”. When this system is zoomed in to see small targets, only a small area of ground is viewable. When the system is zoomed out to view large areas, smaller details are not visible to the user. As such, stabilized “soda straw” video systems struggle when the application calls for finding small objects in very large areas. They are not an ideal match for industrial inspections or wide-area land management surveys. Overwatch developed an imaging system with  greater image resolution and area coverage for low-altitude manned and unmanned aircraft. In addition, to deal with all the data, Overwatch developed automated image processing software to turn imagery into geospatial intelligence.  

TK-series camera systems

Overwatch Imaging’s TK-series camera systems are designed around a unique, nadir-pointing pitch, roll and yaw stabilized mount. The system features an imaging module that holds application specific sensors and optics. There's also an on-board mini-supercomputer and on-board storage for custom image processing algorithms. To cover large areas with high resolution, engineers developed a step-stare scanning camera motion feature. Compared to traditional mapping systems, this feature increased the per-pass data by 4x. Users can map 4x the amount of ground per pass, increase the resolution by 4x or a combination of both. To implement this advanced imaging technique Overwatch required an INS which could mount to the optical bench.  

INS integration

Mounting the INS directly to the optical bench provided a few advantages. The team no longer needed to rely on aircraft INS for data, it removed the requirement for encoders on the individual axes, and reduced the control system and electronics complexity. Additionally, it provided a smaller overall form factor (critical to small and medium-sized UAS). It was also critical that the INS provide low latency attitude data within 0.1° accuracy for pitch and roll in dynamic conditions. This created a faster workflow, lessened the load on the onboard processor for real-time image stitching and allowed for operation at larger standoff ranges. The engineers at Overwatch surveyed the market and down-selected several inertial products from a variety of suppliers. The focus was to identify a solution with the highest accuracy in the smallest form factor, for the best price. The VectorNav VN-200 Rugged GPS-aided INS out competed all competitive products in each of these categories.  

VN-200

The VN-200’s ability to output accurate position and attitude data at up to 400 Hz and high gyroscope angular rate range (±2000 °/s) allowed the TK-series to maintain accurate attitude estimates while performing the step-stare scanning motions. “VectorNav has an excellent reputation in the marketplace,” said Greg Davis, Founder of Overwatch Imaging. “When a review showed that the VN-200 surpassed other INS solutions in size, cost and performance our choice was clear.” The VN-200 plays a vital role in the TK-series payloads. It provides valuable data for platform stabilization, roll sweeping, step-stare functionality and accurate geolocation of target objects, setting the TK-series apart from its competition. In October 2016 Textron Systems announced the integration of Overwatch Imaging’s TK-7 Firewatch featuring the VN-200 into the Aerosonde Small UAS. The TK-7 Firewatch features multi-megapixel color focal plane array and co-boresighted infrared sensors that enable the system to automatically detect anomalies, such as hot-spots for wildfire mapping. This enables wildland fire crews and forest health managers to more effectively monitor large areas, providing critical analysis, reporting and rapid response capability. Overwatch Imaging’s TK-series is in use in a multitude of new applications -- from vegetation management and infrastructure inspection to target auto-detection and geolocation.

FAA Warns Drone Flyers: Save a Life, Stay Away from Wildfires

If you fly your drone anywhere near a wildfire, you could get someone killed. That’s the stern warning the Federal Aviation Administration (FAA) and U.S. wildland fire agencies have for pilots of unmanned aircraft who interfere with fighting wildfires. Unauthorized drone flights are a serious risk to first responders and anyone in the fire’s path.  

Authorized missions only

Authorized drone missions by the proper authorities can yield valuable information to firefighters. Such missions help detect hotspots, chart a fire’s spread and the progress in controlling a blaze. But when an unauthorized drone is spotted, it may force all authorized helicopter and airplane operations to cease. Unauthorized drone flights create collision hazards to firefighting aircraft. They also distract pilots who are already operating in stressful and challenging conditions. Wildland fire agency reports give a sense of how a single errant drone can disrupt operations: “Drone spotted by pilot at eye level during [helicopter] bucket work… spotted a drone over fire. All helicopter operations shut down…UAS incursion stopped aerial firefighting assets… UAS intrusion into TFR (Temporary Flight Restriction). Helicopters disengaged from fire….” A disruption to any efforts to fight wildfires is incredibly dangerous...and simply not worth it.  

Disruptions can cost a life

“If you own a drone, DO NOT fly near or over a wildfire,” said Dan Elwell, FAA Acting Administrator. “It’s against the law, and firefighting aircraft could be grounded, disrupting time-critical firefighting efforts. Your hobby is not worth another person’s life.” “Most members of the public would never dream of standing in front of a fire engine to stop it from getting to a wildfire, but that’s essentially what they’re doing to aerial firefighting aircraft when they fly a drone over or near a wildfire,” said Jennifer Jones, spokesperson with the U.S. Department of Agriculture Forest Service at the National Interagency Fire Center in Boise, Idaho. If unauthorized drone operations interfere with wildfire suppression, law enforcement, or emergency response efforts, those drone operators could face civil penalties that exceed $20,000 and potential criminal prosecution. Anyone who witnesses or has information about an unauthorized drone flight over or near a wildfire should immediately contact local law enforcement. Deterring interference with first responders, as well as giving way to other aircraft in the sky, becomes more important as drone use expands exponentially. The FAA’s rules for flying unmanned aircraft are clear: Keep your drone away from other aircraft operations, including aerial firefighting missions. You just might save someone’s life.
