EN-300 Precision Fiber Optic IMU/INS. The EN-300 inertial system is designed to be compatible in form, fit and function with a legacy equivalent, but with the higher accuracy and performance needed for GPS-denied navigation, precise targeting and line-of-sight stabilization.

It features navigational-grade performance with 0.04°/hr gyro bias and 0.1-mg accelerometer bias stability with ultra-low 0.007°/hr angle random walk.

Internal signal processing provides full stand-alone or aided navigation, and as an option can provide standard IMU delta velocity and delta theta.

UAVOS has successfully tested its new two-stage parachute system. The new parachute system provides slow descent of a UAS at high speed. It includes two parachutes — the pilot chute and a main chute used to slow and stabilize the UAS.

The decrease in the load speed on the UAS occurs due to the main chute opening delay function, when the pilot chute opens first. The parachute system is designed for UAS with speeds of up to 280 mph (450 kph) and weight of up to 110 lb (50 kg).

Watch the parachute in action:

The pilot chute allows safe, slow descent of the UAV during the main parachute deployment, as well as to open up the main chute at a minimum altitude.

After landing, the group of the main parachute lines is automatically unfastened to collapse the canopy of the main chute and releases after touchdown to avoid dragging the aircraft along the ground. Unfastening is carried out by the lock of a three-step release:

Stage 1: Opening the pilot chute
Stage 2: Opening the main chute
Stage 3: Release of the group of lines of the main parachute

“In the aircraft safety developments, saving an entire aircraft through a deployable parachute system is a crucial thing,” said Aliaksei Stratsilatau, CEO and lead developer of UAVOS. These trials have generated an amount of data that allows us to quantify the performance of parachute system for future missions. Computer modeling cannot capture all the complexities. Parachutes encounter turbulent and dynamic airflow, which is almost impossible to replicate with computers. The only way to get a handle on all the possibilities is test.”

Next-generation phase noise instrument combines timing technologies in a smaller, higher performance measurement instrument

Photo: Microchip Technology

To help research and manufacturing engineers make precise and accurate measurement of frequency signals, including those generated by atomic clocks and other high-performance frequency reference modules and subsystems, Microchip Technology Inc. has announced the availability of the new 53100A Phase Noise Analyzer, a next-generation phase noise test instrument.

The 53100A Phase Noise Analyzer is designed for engineers and scientists who rely on precise and accurate measurement of frequency signals generated for 5G networks, data centers, commercial and military aircraft systems, space vehicles, communication satellites and metrology applications.

Capable of measuring radio frequency (RF) signals up to 200 MHz, the new test instrument rapidly acquires frequency signals and characterizes the phase noise, jitter, Allan deviation (ADEV) and time deviation (TDEV) quickly and precisely. All attributes of a frequency reference can be completely characterized with a single instrument within minutes.

The 53100A Phase Noise Analyzer enables a variety of configurations by allowing up to three separate devices to be tested simultaneously using a single reference, enabling higher capacity for stability measurements. At 344 x 215 x 91mm (13.5 x 8.5 x 3.6 inches), the phase noise test instrument is small enough for integration into manufacturing automated test equipment (ATE) systems, yet powerful enough for laboratory-grade metrology. Its interface provides backward compatibility with Microchip’s 51xxA test sets’ command and data stream, reducing the need to redesign existing ATE infrastructure.

The 53100A Phase Noise Analyzer provides flexibility by allowing an input reference device to be connected through the front panel at a different nominal frequency than the device under test — allowing a single reference to characterize a variety of oscillator products. Rubidium frequency standards such as Microchip’s 8040C-LN or a quartz oscillator such as Microchip’s 1000C Ovenized Crystal Oscillator (OCXO) could be used as a reference as well as other manufacturers’ precise oscillators.

The 53100A Phase Noise Analyzer is available now. Microchip supports the 53100A Phase Noise Analyzer with technical support services as well as an extended warranty.

Xsens, manufacturer of motion-tracking modules, has launched real-time-kinematic (RTK)-compatible motion trackers. The development is designed to bring centimeter-accurate positioning within reach of a new generation of affordable commercial devices.

The RTK extension to conventional satellite positioning signals reduces the maximum positioning error from around ±1 meter in standard commercial GNSS receivers to typically ±2 centimeters. Companies developing innovative new products in non-military markets such as smart farming, autonomous vehicles and coastal maritime equipment have been keen to take advantage of high-precision RTK capability to enable new applications and more automated functions, according to an Xsens press release.

The MTi-680G is a new product in the Xsens MTi 600-series. The MTi-680G, an integrated GNSS/inertial navigation system (INS) module, features an integrated RTK GNSS receiver, as well as providing synchronized 3D attitude (tilt, inclination) and heading outputs.

The new MTi-680G also features upgraded firmware that substantially accelerates the module’s internal signal processing compared to non-RTK modules. Synchronizing the global position coordinates with the module’s attitude, heading and velocity outputs, the MTi-680G can provide a comprehensive positioning and navigation output for any carrier device, including of devices such as drones that move at high speed, at a maximum output data rate of 400 Hz.

The RTK-enabled module also offers these features:

• Precise factory calibration of every production unit
• High immunity to magnetic interference
• Adaptive firmware operation to optimize performance in various types of scenario
• Easy-to-use, free MT Software Suite developer tools to accelerate integration into end-product designs
• Out-of-the-box operation with Xsens’ MTi development kits

“Centimeter-accurate positioning at an affordable price for commercial applications — this is the promise of the new RTK-compatible MTi-680G product,” said Boele de Bie, Xsens CEO. “From seed-sowing agricultural robots to autonomous cargo ships, a whole new generation of applications is now possible thanks to the centimeter-level accuracy of the MTi-680G’s position measurements.”

The MTi-680G is available for sampling now.

New Matrice 300 RTK and Zenmuse H20 series cameras ready for new generation of work, including digitalization and artificial intelligence (AI)

DJI has unveiled its most advanced commercial drone platform, the Matrice 300 RTK (M300 RTK), along with the Zenmuse H20 Series, a hybrid, multi-sensor camera.

DJI engineered the all-in-one, high-tech solution for areas of work never explored before in precise aerial inspections and data-collection missions.

“With the M300 RTK flying platform and the Zenmuse H20 camera series, we are providing a safer and smarter solution to our enterprise customers” said Christina Zhang, senior director, Corporate Strategy at DJI. “This solution sets an entirely new standard for industrial UAV solutions, significantly enhancing operations across public safety, law enforcement, energy, surveying and mapping as well as critical infrastructure inspections.”

The M300 RTK is the first DJI product that integrates modern aviation features, advanced AI capabilities, six directional sensing and positioning system, a UAV health management system, and 55 minutes’ flight time.

The drone platform has AES-256 encryption and an IP45 weather-resistant enclosure. It has a built-in all-new OcuSync Enterprise transmission system that provides a triple-channel 1080p video transmission signal reaching up to 15 km away.

The M300 RTK can support up to 3 payloads simultaneously and has a maximum payload capability of up to 2.7 kg.

“For our teams working in the oil & gas industry, performance and safety are not optional,” said customer Adam Serblowski, Robotics Theme Lead at Shell. “We cannot compromise on our pursuit of utilizing the best and most efficient tools available. The DJI Matrice 300 RTK proves to be an ideal upgrade over the existing DJI product line, and it helps us to further enhance the benefits of our drone programs. Our productive partnership with DJI will continue to help elevate safety in the world’s largest industry.”

With the Zenmuse H20 Series Camera

Combined, the M300 RTK and Zenmuse H20 Series solution offers users two intelligent ways to collect data:

• Smart Pin & Track. Intelligent functions that enhance synchronization of aerial intelligence in coordinated missions. It includes PinPoint, a function that allows users to mark the subject of interest and instantly share the precise location data to a second operator or if necessary to ground teams via DJI FlightHub; and Smart Track, which allows users to automatically detect and track a moving object, even at extreme distances, while synchronising the subject’s dynamic location in real time.
• Smart Inspection. A new set of features developed to optimize routine data collection missions such as power lines, railway and oil and gas inspections. It consists of Live Mission Recording for recording sample automated missions in real time; AI-Spot Check, which enables data collection from exactly the same location every time, greatly improving the accuracy of automated missions. After photos from a sample waypoint inspection mission have been recorded, operators are able to mark the subject of interest. During subsequent automated flight missions, AI algorithms perform a comparison between the marked subject and current live view, thus correcting the camera orientation accordingly to deliver accurate and consistent results; and Waypoints 2.0 — an improved mission planning system offering up to 65,535 waypoints, while supporting an array of consecutive actions, 3rd party payloads, and more.

Aviation-Grade Situational Awareness. Inspired by today’s modern aircraft, the M300 RTK features a Primary Flight Display (PFD) that merges real-time flight and navigation data into one integrated display. Besides standard telemetry data like altitude and speed, the M300 RTK PFD provides obstacle data for visualising nearby obstacles during flight, enabling pilots to adjust flight trajectory if needed. These enhancements allow users to keep track of the aircraft while further enhancing the pilot’s situational awareness.

Dual-operator mode. New to DJI’s commercial drone platforms and exclusive to the M300 RTK, is Advanced Dual Operator Mode – multi-pilot control protocols that enable the execution of missions with enhanced safety, reliability and flexibility.

The M300 RTK, when controlled by two pilots, gives each pilot equal access to gain flight-control priority, the transfer of which is displayed by a series of icons on the DJI Smart Controller Enterprise. If one pilot becomes compromised or their controller loses battery or connection, the other pilot gains full control over the M300 RTK and its payloads.

When training new pilots, the teacher/main pilot can safely take over flight control if necessary.

Improved safety and reliability

The M300 RTK comes with new and improved safety and reliability enhancements, including:

• AES-256 Encryption: for secure data transmission of the command & control uplink and video transmission downlink.
• AirSense (ADS-B technology): for enhanced airspace safety.
• Anti-Collision Beacon: for increased aircraft visibility, especially in low-light conditions.
• IP45 Protection Rating & Self-Heating Battery: for adverse weather conditions (-20 to 50° C).
• 6 Directional Sensing and Positioning System: offers a maximum detection range of up to 40 m horizontally, with options to customize the aircraft sensing behavior via DJI Pilot.

As with modern-day jetliners, the M300 RTK offers an integrated UAV Health Management System (UHMS) to optimize fleet maintenance. It records the aircraft’s flight data throughout its entire lifecycle, and utilizes the drone’s hardware and software systems to understand current aircraft performance and determine when it should be serviced. Taking advantage of this new system, users can get a quick overview of all critical aircraft systems, manage firmware updates across an entire fleet, track pilot hours and review flight missions.

DJI Zenmuse H20 Series

The new camera payloads are designed to improve mission efficiency. The Zenmuse H20 series offers DJI’s first Hybrid multi-sensor solution, allowing capture of any kind of images for industrial applications and public-safety missions where efficient time management and immediate access to multiple layers of visions are paramount.

The H20 Series is IP44 rated, which protects enclosures from splashes of water from any direction.

The H20 series comes in two versions:

• The H20, a triple sensor with a 20-MP, 23x hybrid optical zoom camera, a 12-MP wide camera, and a laser range finder covering distances from 3 to 1200 meters
• The H20T, a quad sensor that adds a 640 x 512 radiometric thermal camera, allowing operators to see what is invisible to the human eye using high thermal sensitivity at 30 frames per second video definition.

Integrated user interface

To enable pilots to operate so many sensors at once, the accompanying DJI Pilot app interface was redesigned. The new user interface lets pilots quickly switch between cameras and simplifies the process of zooming in and out by letting pilots preview the zoom field of view on top of the wide angle or thermal camera footage.

With a multi-sensor integrated user interface, the Zenmuse H20 series allows users to smoothly switch between wide, zoom or thermal cameras. It also includes features for maximum flexibility when used on time-sensitive missions.

• High-Res Grid Photo: Captures in one snap detailed imagery of defined subjects with the help of a custom grid. The images can be stored for later detailed inspection.
• One-Click Capture: Captures videos or photos of up to three cameras simultaneously without having to manually switch between camera views or repeat a mission.
• Night Scene: Gains clearer visibility when lighting conditions are not optimal.

The M300 RTK and Zenmuse H20 series are available for pre-order from official DJI Enterprise dealers and will start shipping in Q2 2020.

SLAM-based mobile mapping with integrated 360° color is a rugged, geo-enabled, high-density and versatile workhorse

Photo: Kaarta

Kaarta, an innovator of real-time mobile 3D reality capture, has announced beta testing on Stencil Pro, a versatile professional-grade mobile mapping platform with dimensional and visual fidelity.

According to a Kaarta press release, “Whether on the road or on a job site, in a warehouse or an office, an underground mine or in the woods, along a utility corridor or a railway, the multipurpose Stencil Pro mobile mapping system is ready to take on the most challenging environments with impressive speed, providing accurate and visually stunning results.”

An all-in-one system to scan, process and view captured data in real time, Stencil Pro offers panoramic high-definition 4K imagery and colorized point clouds. With robust surround-view perception in a wide range of light conditions, Stencil Pro is optimized for both indoor and outdoor performance.

Featuring a 32-line high-density, low-noise lidar with a range of 120 meters (nearly 400 feet) and a data rate of 600,000 points per second, Stencil Pro produces a highly accurate 3D model in minutes.

With an IP65 rating, Stencil Pro is safeguarded against adverse elements such as dirt, dust, fog and rain, making it the ideal tool for infrastructure mapping, mining, forestry, earthworks, construction and other harsh environments. Stencil Pro’s rugged and versatile design is adaptable to many environments, capturing data amidst poor weather, dusty work environments, and below-ground cavities or when mounted on vehicles, locomotives, ATVs and other platforms.

Like all Kaarta systems, Stencil Pro’s simultaneous localization and mapping (SLAM) capabilities means it operates in GNSS-denied areas such as indoor, underground, under canopy, or in urban canyons. However, it is also fully geo-enabled for the many applications such as street, corridor and rail mapping where the addition of a GNSS signal is highly beneficial.

Stencil Pro integrates the Trimble BD-990 receiver, AV-28 antenna and a range of other third-party GNSS antennas. It supports positioning accuracy enhancements through live RTK/NTRIP processing as well as PPK corrections based on data provided by the NOAA CORS network or a user-supplied base station.

GNSS positioning data is used to align and geo-register data, providing global accuracy and further enhancing the fidelity of large area scans and long, linear scan paths. With the ruggedized design, enhanced power capabilities, as well as the option of incorporating the industry-leading SLAM accuracy in addition to – or independent of – geopositioning, Stencil Pro has the scale of traditional mobile mappers for a fraction of the investment.

The onboard GNSS and color cameras are fully integrated into real-time capture, allowing for optimization of collected data as well as flexibility in output. The advantage of absolute positioning and accuracy coupled with 360 degree imaging technologies produces a true color, rich and robust point cloud when needed. If a colorized point cloud is not required, or GNSS is not available, reliance on other sensors is seamless.

“Billions of dollars of commercial real estate transactions, construction projects, infrastructure maintenance and natural resource management decisions rely on understanding existing conditions data,” said Kevin Dowling, Kaarta CEO. “Obtaining up-to-date data for these environments is laborious, time consuming and expensive with current methods. Even in the most challenging scenarios, Stencil Pro rapidly provides the answers needed for managers to make informed decisions.”

Stencil Pro is powered by either 100-240 VAC input (or 12V with an inverter) or using its two hot-swappable batteries which last for up to 3 hours of scanning. Stencil Pro’s intuitive user interface makes data capture and processing simple. The user experience includes one-button scanning, real-time scan monitoring and streamlined post-processing options for maximizing data clarity and usability. Remote operation with a touchscreen monitor allows for mounting Stencil Pro on a multitude of transports. When hand-carried, scan status can be started and stopped with the press of a button.

Stencil Pro is built on Kaarta Engine, Kaarta’s patent-pending approach to solving the SLAM problem. Kaarta’s unparalleled expertise in localization – a result of its deep robotics roots – delivers definitively lower drift error than alternative SLAM systems by an order of magnitude. Kaarta’s proven technology, quality, and accuracy is trusted by AEC, geospatial, natural resource management and autonomous mobile robot professionals worldwide.

Limited quantities of Stencil Pro will be available to ship in June. Those interested in being considered for early access to discuss a specific application, schedule a demonstration or review sample data sets can apply for the Stencil Pro Early Access Program.
