  • The sky’s alive at AUVSI’s Xponential 2017

    The sky’s alive at AUVSI’s Xponential 2017

    The Association for Unmanned Vehicle Systems International (AUVSI) Xponential 2017 show, May 8-11 in Dallas, convened a global community of commercial and defense suppliers in intelligent robotics, drones and unmanned systems. It showcases the broad forefront of autonomous vehicles generally, but in-flight in particular, and there were plenty of expanded capabilities and expanding applications on display.

    In one of several keynotes over the course of the four-day show, Intel Corporation CEO Brian Krzanich predicted that in the oncoming era of driverless cars and autonomous aircraft, the most important aspect of such vehicles will be the data they collect rather than their performance. Big data and cloud processing are somehow tied into UAVs in his vision of things. Sometime soon, he forecast, autonomous devies “will have the ability to make decisions.”

    Swarming drones have military potential, according to a 33-year career Marine who now works at the Potomac Institute for Policy Studies. Bill Powers described how a Navy program, the Low-Cost UAV Swarming Technology (LOCUST) uses drones to jam enemy communications and waste its resources by drawing fire. The Naval Research Laboratory dploys Close-in Covert Autonomous Disposable Aircraft (CICADA), with onboard sensors that relay atmospheric conditions as well as possition, time and altitude relating to battlefield conditions.

    Watching the Watchers

    With all the drones in the air, managing them and keeping the commercial airspace safe and uncluttered has become a towering problem. Several companies at AUVSI introduced unmanned traffic management (UTM) systems.

    Among them, Gryphon Sensors introduced Mobile Skylight, an operational mobile UTM system designed for rapid deployment.

    Drone security applications span, according to the company, airport security, critical infrastructure protection, VIP security, embassy protection and border security. In the beyond visual line-of-sight (BVLOS) realm, UTM applications to be enabled by Mobile Skylight include: first responders (EMS, fire and police), precision agriculture, delivery, utility and infrastructure inspection, media and entertainment, mapping and surveying, construction and mining.

    In short, everywhere drones go, they will need to be tracked and managed.

    Mobile Skylight combines multiple technologies and an array of self-contained sensors, to serve as a mobile command center. The system is provided in a four-wheel drive van with off-road capabilities. It also integrates with third-party sensor inputs, and automatically records essential data for post-mission analysis and playback.

    Using a dual-band mesh network, Mobile Skylight is capable of forward deploying a multispectral suite of sensors. Its integrated radar has been designed for 3-D detection of low-flying, small UAS and general aviation at ranges out to 10 kilometers and 27 kilometers, respectively. The system has built-in target tracking and classification to help quickly identify cooperative and non-cooperative targets. It also tracks multiple, simultaneous targets, providing a comprehensive picture of the airspace.

    Yeah, Heavy

    One novel application is heavy-lift drones for the construction and perhaps open-pit mining, quarrying and other weighty sectors. Griff Aviation, a Norwegian company that has set up a manufacturing plant in Florida, displayed its Super Heavy-Lift model, the Griff 300.

    The GRIFF 300 is an unmanned aircraft with customizable payload options that make it suitable for a variety of professional applications. The company states that it can lift 225kg (496lbs) in addition to its own 75kg (165lbs) weight. It features a flight time of 30-45mins, depending on payload. “The next model that will be produced will be able to lift 800kg (1,764lbs). Then we will continue to increase lifting capacity even further,” said CEO Leif Johan Holand.

    Several aisles over on the show floor, Skylift Global also featured a drone in the heavy lifting class.  “Current prototype is 100 pounds and carried an additional 100 pounds easy. Currently undergoing testing for up to 400 pounds,” says its CEO Amir Emadi.

    Skylift has signed agreements with companies in southern California to start deliveries of cold-chain logistics. Its heavy-lift capability can carry the added weight of refrigeration (think Amazon Fresh, says Emadi). Skylift also is in collaboration with JPL and Caltech to showcase a platform to DARPA for autonomous sense and avoid.

    Neither company has GPS aboard their workhorses yet but see no problem and plenty of opportunity in adding it as their business develops.

    Experienced GNSS Companies

    NovAtel had on display its range of high-precision GNSS receivers, antennas, and augmented systems for ground, marine and airborne unmanned applications. Its equipment meets requirements for military and commercial applications, and specific to UAV applications the company offered the OEM625S SAASM GPS+civil RTK receiver, GAJT anti-jam antennas, TerraStar PPP correction services and SPAN GNSS+INS for 3D position, attitude and velocity.

    The latter will be featured in the cover story of GPS World’s June issue, differentiating performance of various grades of IMUs in a tightly-coupled inertial/GNSS integration. Exploring IMU specifications and correlating them to performance of a final product can be daunting, as differences between MEMS sensors are not always apparent. The article will present achievable performances in fusion technology across a range of IMUs among the best in their respective performance categories.

    Spirent Communications took a dual approach, displaying what they termed an entry-level simulator (although fully upgradeable as needs develop) for UAV manufacturers who are new to GPS signal testing, and even the need for it. They also had on hand their fully configured GSS7000 for multi-frequency testing, also with a modular approach to enable the precision GNSS simulation system to expand with users’ needs.
    The GSS7000 series offers emulation of all civil GNSS systems and regional augmentation systems, and allows devices to be tested under a multitude of operating environments and error conditions, the company said. The GSS7000 has the flexibility to reconfigure satellite constellations, channels and frequencies between test runs or test cases. Four software control variants are offered.

  • Congress increases funding for UAS research, airspace integration

    More than $20 million for research on unmanned aircraft systems (UAS) was included in an appropriations package that Congress passed and the president signed into law last week to fund the federal government through the end of the fiscal year on Sept. 30. The funding for UAS research is $2.67 million more than last year’s budget request by the Federal Aviation Administration (FAA) to address a host of research challenges associated with integrating UAS into the national airspace system.

    The measure’s section on appropriations for transportation agencies also includes $20 million above the 2016 budget request for the FAA’s air traffic control organization. The increase will provide for the hiring and training of new controllers and accelerating UAS airspace integration. The agreement also includes $11.5 million more than was requested for aviation safety activities for UAS integration, including the addition of six full-time positions to support the certification of new technologies and advance the FAA’s organizational delegation authorization (ODA) efforts and strengthen safety oversight.

  • UAV testing facility selects Harris for BVLOS support

    Grand Sky Airfield Operations, a 217-acre UAS test facility in North Dakota, has selected Harris Corporation to provide an advanced solution to support beyond-visual-line-of-sight (BVLOS) unmanned aerial systems (UAS) flight operations, reducing the need for chase planes to provide constant visual surveillance during flight. Grand Sky tenants will have the ability to conduct BVLOS UAS flights, enabling commercial and government operators to deploy their technologies, test and conduct operations. The announcement was made during AUVSI’s Xponential.

    Harris will provide a customized RangeVue sense-and-avoid solution that delivers real-time situational awareness of surrounding unmanned and manned aircraft traffic, with  multi-sensor surveillance for cooperative and non-cooperative vehicles. airspace situational awareness tool designed specifically for test-range operations for unmanned air systems (UAS). RangeVue puts real-time NextGen surveillance data, obstacle data, flexible background maps and weather information in the hands of the people who are actually in the field testing and validating UAS missions. The solution will cover the 217-acre unmanned aircraft business and aviation park located on Grand Forks Air Force Base, North Dakota.

    It will enhance Grand Sky’s infrastructure for safe and efficient BVLOS UAS operations and testing, ensuring the FAA’s stringent safety requirements are met and eliminating the need for expensive chase planes to track UAS entering, exiting or operating within Grand Sky’s 60 nautical-mile radius airspace.

    Harris’ Grand Sky solution will combine available surveillance sources — including Grand Forks AFB’s radar feed, locally installed ADS-B Xtend and FAA NextGen surveillance data — into a single stream that offers  area coverage and airspace visualization for drone operators. Xtend supplements the FAA’s existing ADS-B nationwide network operated by Harris, which provides precise and reliable satellite-based surveillance for the nation’s air traffic control system.

  • Traffic management systems for UAS requested by UN agency

    The International Civil Aviation Organization (ICAO), a specialized agency of the United Nations, and the Association for Unmanned Vehicle Systems International (AUVSI), announced a Request for Information (RFI) on traffic management systems for unmanned aircraft systems (UAS). ICAO announced the RFI at AUVSI’s Xponential 2017, the  trade show for the unmanned systems and robotics industry.

    As UAS operations become more complex and are increasingly used for both commercial and recreational purposes, UAS traffic management systems, or UTM, are necessary to seamlessly integrate UAS into the airspace and existing air traffic management systems. ICAO will solicit proposals for a global framework for UTM ahead of its Drone Enable UAS Industry Symposium, which will take place in Montreal, Canada in September.

    “ICAO is the natural agency to be gathering together the best and brightest from governments and industry to define the problem so that global solutions can be proposed, debated and agreed,” said Leslie Cary, remotely piloted aircraft systems program manager at ICAO.

    An operational UTM will ensure the safe and efficient use of the airspace as UAS operations become more complex, such as with established navigation routes and point-to-point route segments requiring specific equipage requirements. UTM will integrate UAS into the existing airspace infrastructure to ensure the continued safety of the airspace.

    “Collaboration between stakeholders is key to addressing complex issues such as UTM,” added Brian Wynne, president and CEO of AUVSI. “AUVSI is pleased ICAO is taking steps to explore solutions for UTM that will allow companies to operate globally under the same standards, reducing barriers to innovation and improving safety and security for all aircraft – both manned and unmanned. We look forward to working with ICAO to draw awareness and facilitate industry engagement in the RFI process.”

  • VectorNav supplies IMU for military bomb-disposal robot

    VectorNav supplies IMU for military bomb-disposal robot

    VectorNav Technologies, a provider of embedded navigation solutions, announced at AUVSI’s Xponential that it will supply its surface mount VN-100 inertial measurement unit/attitude and heading reference system (IMU/AHRS) to Neya Systems for a custom version of that company’s UxAB module.

    Neya Systems will in turn deliver its custom version of the UxAB platform to Northrop Grumman for that company’s Advance Explosive Ordnance Disposal Robotic System (AEODRS) Increment 1 delivery, an autonomous bomb-disposal robot, to the U.S. military. The AEODRS unmanned ground vehicle “back-packable” increment 1 system weighs less than 35 pounds and comprises the handheld operator control unit, communications link, mobility capability module, master capability module, power capability module, manipulator capability module, end effector capability module, visual sensors capability module, autonomous behaviors capability module and other minor components.

    The UxAB is a a fully self-contained semi-autonomy and autonomy capability module that includes GPS waypoint navigation, multi-joint manipulator control (with self-collision avoidance), retrotraverse, return-to-comms and optional obstacle avoidance behaviors.

    VN-100+SMD_LeftAbout the size of a postage stamp, VectorNav’s surface mount VN-100 is a temperature calibrated MEMS-based IMU/AHRS that includes 3-axis accelerometers, gyros and magnetometers. The module delivers to users a real-time 3D orientation solution that is continuous over the complete 360 degrees of motion at rates of up to 400 Hz. In addition to calibrated IMU and AHRS functionality, the VN-100 includes VectorNav’s Vector Processing Engine (VPE), a suite of proprietary sensor fusion algorithms running onboard the sensor that deliver real-time magnetic & acceleration disturbance rejection, adaptive signal filtering, dynamic filter tuning, and on-board Hard & Soft Iron compensation.

    The VN-100 surface mount module is being integrated directly into the electronics board of Neya Systems’ UxAB platform. Neya is using the calibrated pitch and roll estimates to assist in its controller functionality, for example to provide warning when the robotic module is in danger of tipping. The VN-100 AHRS magnetometer-based heading solution is used for waypoint navigation. VectorNav is providing platform specific hard/soft iron calibration expertise to ensure the magnetometer-based heading solution takes into account the magnetic signature of the UxAB module and provides accurate navigation in a variety of environmental conditions.

    AEODRS is the next generation of Explosive Ordnance Disposal robotic systems, designed as a follow-on and capability upgrade to existing deployed platforms. AEODRS is based on an open architecture, and Neya’s Autonomy Module will conform to the logical, electrical, and physical interfaces that are required by this architecture. Neya will be adapting its commercially available UxAB platform to comply with AEODRS Capability Module requirements.

     

  • Drones, swarms, artificial intelligence and virtual reality now rule

    Drones, swarms, artificial intelligence and virtual reality now rule

    This e-newsletter marks the sun setting on the career of GeoIntelligence Insider columnist and contributing editor Art Kalinski, long active in geospatial circles. Art is handing the journalistic reins to William Tewelow, a former intelligence specialist with the U.S. Navy. He also served a special assignment at the U.S. Department of Transportation and is currently  a manager with the U.S. Federal Aviation Administration (FAA). The following discussion muses about the direction of our geospatial tradecraft in the coming years.

    Tewelow’s Geointelligence column will alternate monthly with Mike Jones’ Defense PNT column. Every issue of this newsletter also brings you the latest news on both expanding fronts, hardware and software, in the defense and security realm.

    Passing the torch

    A conversation between retiring GeoIntelligence editor Art Kalinski, GISP, and his successor, William Tewelow, GISP.

    Counter-drone technology research and operation efforts are helping to prepare for the potential threat of drone swarms. This Lockheed Martin concept was explored at "Technology That Counters Drone Swarms.”   (Image: Courtesy of Lockheed Martin)
    Counter-drone technology research and operation efforts are helping to prepare for the potential threat of drone swarms. This Lockheed Martin concept is explored in “Technology That Counters Drone Swarms.”

    Art: A factor of life is that you just can’t predict with certainty where technology is headed or what the issues will be. Several weeks ago I attended a UAV (unmanned aerial vehicle) users group that seemed like a glimpse of the Wild West. I thought the key discussion topics would be the latest technology which seems to change almost weekly. That was not the case. The key discussions were the same as the early days of GIS: legal liability, jurisdictions, data ownership, administrative issues and so on, as the FAA changes the rules and regulations. I began to see that there will be more employment opportunities for lawyers than techies and pilots.

    Although most of the attendees at the conference were geospatial/first responder users, I’ve learned of a growing community of non-traditional users such as power line inspectors and even tower painters. Yes, a tower painting company using tethered UAVs to paint in dangerous locations such as bridges, tanks and towers. At first I thought that would be difficult but by using a tethered system, heavy batteries are eliminated and bigger UAVs will permit heavier hoses, etc. Although the FAA had little interest in tethered balloons and UAVs, that could change as the size, altitude and potential crash radius expands.

    This is just one example of how our technology is moving in many unplanned directions, everything from UAVs with new ways of collecting imagery to more exotic topics such as artificial intelligence, machine learning, augmented reality, virtual reality (VR) and gamification. The entire trade craft is evolving in ways I don’t think anybody could have predicted just a few years ago, much less a decade ago. It will be interesting to see where it goes.

    William: You mentioned several new technologies mixing things up. Small sats are also making a significant impact. They are game changers. Imagine the traditional 2D satellite imagery base map. With the tech we have now 3D base maps are possible and have been for a long time with DEMS. Now, small sat imagery can be overlaid atop the 3D basemaps providing fresh imagery with periodicities of 24 hours or less, including multi-spectral. I’ve even seen small sat video overlays. That’s game changing.

    Art: Not only small sats but the work being done with drone swarms is an exciting new area. If data needs to be collected in a hostile area or if flight clearance in a busy air corridor was limited, a swarm of maybe 100 drones could capture a wide swath of data at high resolutions, with multiple spectrums in very short order.

    Virtual reality and augmented reality are two areas which have always intrigued me and they are coming to fruition. When I started out in GIS, I told people working for me to do the best we could building our regional database because at some point we would have construction workers wearing goggles that will augment the reality of what they are seeing with GIS data. That day is here and people are finally starting to do that. So, the entire concept of AR (augmented reality) and VR I find extremely exciting.

    William: Yes, absolutely, in fact I believe they used drone swarms in the hostage situation in Algiers in 2014. And you are right. VR and AR use for first responders is especially critical. Say you’re a disaster relief person at night in a smoke-filled building. Night vision and thermal vision reach a practical limit. However, combining the vision devices with AR you may be able to navigate through the environment well enough. AR shows at least what should be there so accurate and timely data is critical. I can see this is where things are headed. Additionally, more mundane tasks such as design and modifications of structures could be enhanced. Work is already being done using AR and VR to facilitate the design process.

    Art: VR started as fun and games but to me serious use VR is where the new and exciting action will be for geospatial practitioners. Virtual trainers I saw recently included small arms and artillery trainers for the military to a less exciting but equally impressive virtual trainer to teach arc welding and even spray painting a car. Significantly more critical was a VR surgical trainer where the muscle learning and hand eye coordination required is significant. It’s obviously quicker, easier and cheaper to practice virtually than on a real human or real equipment and the VR environment is just one short step away from surgical robots operating in remote locations.

    William: Right, and you are touching on gamification, where VR can be used to train toward certain results. Take the military, for example, gamification can save all manner of resources – bullets, people, buildings the environment. Additionally, users can also scale up or down. The VR environment doesn’t just mean roads, maps or mountains. You can get down to a micro level.

    Art: It’s interesting you mention that. One aha! moment I had years ago was at the first Esri User Conference in San Diego. I went through the map gallery. A lot of examples of different uses for GIS were on display and one person had created a map of the human circulatory system using ArcView Network Analyst. Looking at it I thought, of course, whether its blood vessels or interstate highways, it’s a network; so, this individual was using a geospatial tool to map the entire blood vessel network.

    William: We are now in the realm of nano technology, where things are small enough to work on blood cells. Imagine steering straight towards a cancer cell by pinpointing a location in relation to the body.

    Art: It’s almost like the movie “Fantastic Voyage” except in a virtual environment.

    William: Yes. Being able to put the nano technology right where it needs to be means entering an age of focused medicine so that a pill releasing nano particulates doesn’t impact the whole body just the area needed. That’s another discussion in itself. Of course, all of that will have to be controlled, mapped and understood in terms of what it’s doing and where it’s going in relation to the body.

    Art: One area that is very concerning to me is cyber. All of this stuff we’ve talked about is very vulnerable whether stealing data or doing damage to a society. Thwarting those threats is getting into machine learning, AI and other topics bordering science fiction.

    William: Yes, and you are getting into artificial intelligence. IBM, Google, Amazon, Facebook, Microsoft and our three letter agencies are all investing into the world of Geospatial AI. I am not sure where GeoAI will end up but we can already see some hints. The amount of geospatial data is overwhelming and imagine the explosion happening with IoT. How will all that be managed? GeoAI will do pattern recognition so in effect GeoAI is assisted intelligence.

    As an example let’s consider a high profile event. There are 1000’s of parameters that need to be tracked such as surveillance cameras, social media feeds, a suite of sensors, etc. Identifying critical patterns is crucial so Geospatial Assisted Intelligence can monitor the parameters of the event then notify the analyst when a triggering event occurs. That’s where the technology is going where it has to go.

    Art: One has to have a truly dizzying intellect to keep track of all aspects of our technology. At the last NGA (National Geospatial-Intelligence Agency) conference, Director Cardillo talked extensively about open systems and open sources which are growing directions for the agency. I believe it’s good to get away from everything being “inside the tent” and taking advantage of the extensive capability in the broad geospatial community. The stated goal is to be able to develop needed geospatial tools, in an unclassified environment, not in months or weeks but literally in minutes to provide those tools to analysts in the field. Things have come so far from the day I was just happy to get a pen plotter to print a simple map.

    William: It really is mind boggling. I was there when full motion video began and that was dynamic 2D imagery but then it made the jump to 3D dynamic imagery and my circuits fried. I still have a hard time comprehending all the data crunching that goes into it and it is now almost standard. The future is amazing. That is the direction I want to continue to explore.

    Editor’s Note  from Art: Since we are approaching Mother’s Day and Memorial Day, I’d like to call your attention to my best column addressing mothers and the military. 

  • Septentrio’s newest receivers protect against jamming interference

    Septentrio’s newest receivers protect against jamming interference

    Septentrio has launched two new GNSS boards. The AsteRx-m2 and AsteRx-m2 UAS OEM boards provide GNSS positioning with interference mitigation technology on ultra-low-power boards. The boards are being showcased at AUVSI’s Xponential 2017 this week in Dallas, Texas.

    AsteRx-m2
    AsteRx-m2.

    The credit-card sized AsteRx-m2 and the AsteRx-m2 UAS offer all-in-view multi-frequency, multi-constellation tracking and centimeter-level real-time kinematic (RTK) position accuracy for low power. Both boards can receive TerraStar satellite-based correction signals for precise point positioning (PPP).

    The AsteRx-m2 and the AsteRx-m2 UAS feature Septentrio’s AIM+ interference mitigation system: an on-board interference mitigation technology that can suppress a wide variety of interferers, from simple continuous narrowband signals to complex wideband and pulsed jammers. The increasing levels of radio frequency pollution — coupled with the intrinsic danger of self-interference in compact systems such as UAS — makes interference mitigation a vital element in any UAS GNSS system, Septentrio said.

    AsteRx-m2 UAS receiver.

    The AsteRx-m2 UAS is designed specifically for unmanned systems. It provides plug-and-play compatibility for autopilot software such as ArduPilot and Pixhawk. Event markers can accurately synchronize a camera shutter with GNSS time.

    The board can be directly powered from the vehicle power bus via its wide-range power input. The AsteRx-m2 UAS works seamlessly with GeoTagZ software and its SDK library for RPK (reprocessed kinematic) offline processing to provide RTK accuracy without the need for ground-control points or a real-time datalink.

    “The market demands increasingly accurate and reliable GNSS positioning systems for inspection, mapping and aerial survey,” said Gustavo Lopez, product manager at Septentrio. “Septentrio’s answer is the AsteRx-m2 and the AsteRx-m2 UAS: offering multi-frequency and multi-constellation tracking as well as robust interference protection all for the lowest power on the market.”

    The AsteRx-m2 and AsteRx-m2 UAS are now shipping. Septentrio is located at stand 749 of Xponential 2017.

  • PrecisionHawk launches free software for drone mapping

    PrecisionHawk launches free software for drone mapping

    Commercial drone and data company PrecisionHawk has opened access to its PrecisionMapper professional mapping and analytics software for free.

    With the software, drone operators can snap an unlimited number of photos, create maps without resolution limits, and run algorithms to analyze their data.

    PrecisionHawk announced the launch of the free version of PrecisionMapper today at the AUVSI’s Xponential 2017 conference in Dallas, Texas.

    Drone operators can use PrecisionMapper to generate aerial data using their own drones.

    “Drones have the potential to capture more high-resolution data than any other technology, but we believe that drones are being under-utilized because of the cost barriers around processing, analytics and storage,” said PrecisionHawk CEO Michael Chasen. “Users should be able to walk into any store, buy a drone and use that drone to generate business insights for free.”

    “We believe that this move allows more innovation from more people,” Chasen continued. “PrecisionHawk has gained a lot from the advanced thinking of this community, and this is our way of giving back.”

    By providing this software for free, PrecisionHawk is giving operators of drones with visual cameras the capability to explore the financial value of aerial data in any industry and is encouraging further use and adoption of drone technology.

    Operators can quickly and easily upload imagery collected from a drone to PrecisionMapper. Using GPS information embedded within images, the software automatically stitches together a complete map, viewable in both 2D and 3D. Free users of PrecisionMapper can create up to 60 surveys a year without resolution or export limits.

    In addition, users can add ground control points and access free analysis tools for construction, agriculture, insurance, and energy including:

    • volume calculations
    • 3D models
    • contour maps
    • multiple crop health indices, including visual-NDVI

    “When professionals have the opportunity to get hands-on experience with PrecisionMapper, they will be able to better understand the power of aerial data and how it can be best incorporated into their existing businesses,” Chasen said.

  • Intelligent transportation systems require ‘the ego vehicle’

    Intelligent transportation systems require ‘the ego vehicle’

    Most activity so far in the PNT community has centered around the questions of “Where am I?” and “Where am I going?” and “How fast am I going?” Positioning, navigation and timing. Seemingly that should about cover it. But no.

    Mapping comes into the picture: “What fixed objects are in my environment?” This is actually a corollary of “Where am I?” though let’s not put too fine a point on it.

    All this “I” business. To get to driverless cars and other autonomous vehicles, we will have to look beyond the first person singular, what some researchers call “the ego vehicle.” We must know, with a high degree of precision and certainty, “Where are other moving vehicles?” and “Where are they going?” and “How fast are they moving?” Another order of magnitude, if not several. PNT squared, as it were.

    In the fast oncoming intelligent transportation systems (ITS), future driving (very much present and evolving now) will rely on accurate, reliable and continuous knowledge of the position of other so-called road participants. That’s not just cars, trucks, motorcycles and buses, but includes pedestrians and bicycles and who knows what else — skateboards?

    The first approaches to this requirement use on-board ranging sensors such as camera/vision systems, radar, laser scanners and more. (Some of this “more” is explored in this May’s print cover story, “Look Around.”) This already calls for a significant level of integration with GNSS and inertial systems of the ego.

    But it’s still not enough. A cooperative approach must develop, in which the other road participants actively support the continuous estimation of all relative positions. Not only must they have all the sensors the ego possesses, they must continually communicate all that data with the ego, and conversely. This is what’s called “connectivity.”

    It’s almost as if vehicles are becoming sentient, expressive beings. A bit like us. Bringing new meaning to the expression “the automobile as an extension of the self.”

  • Continental Electronics patents new eLoran transmit method, system

    Continental Electronics patents new eLoran transmit method, system

    Texas company Continental Electronics has patented a transmitter system and method for construction of low-frequency antenna towers significantly lower in height than previously needed for identical coverage.

    “One obstacle to deploying eLoran systems has been the sheer height needed for the transmission towers, each of which requires significant acreage,” said Mike Rosso, vice president of Dallas-based Continental Electronics. “Tower height and land required not only represent serious financial costs, but in some cases adequate space is simply not available. Our technology can reduce tower height and real-estate requirements. With this, reducing antenna tower height by half would reduce required land area to one quarter.”

    The method uses digital adaptive correction, solid-state amplifiers, envelope modulation and a wideband matching network. Any linear distortions within usable bandwidth are removed by digital adaptive correction, according to the company. Envelope modulation is required to achieve linearization for any signal type including Loran. A wideband matching network tunes out capacitive reactance from electrically short antennas, transforms impedance to a value suitable for the transmitter, increases usable bandwidth and suppresses harmonics and out-of-band emissions.

    “We hope this will aid moving forward eLoran deployments around the world,” Rosso added. “Widely used satellite-based navigation and timing services are vulnerable to jamming, spoofing and other forms of interference. The world needs a more resilient solution as afforded by ground-based solutions such as eLoran.”

  • Cellphone towers in the sky? Fenix thinks so

    A drone that weighs less than 50 pounds can provide fully functional 4G cellphone service.
    A drone that weighs less than 50 pounds can provide fully functional 4G cellphone service.

    Virginia-based Fenix Group has partnered with Martin UAV, a Texas-based manufacturer of rugged utility drones, to launch an under-55-pound drone capable of providing fully functional 4G cellphone service.

    While Fenix Group plans to issue its first production units to the U.S. Department of Defense and first responders, it anticipates demand from telecommunications providers, oil and gas companies, and crisis response units worldwide.

    It also could mean connectivity in remote parts of the world.

    In addition to providing a coverage area on the ground, the payload is also able to stream encrypted video from the drone’s camera system to anyone on the network. In the future, soldiers, search and rescue teams, and first responders will have access to drone video from their phones.

    The Fenix team also enabled Internet access so that command centers could access the feed from anywhere in the world.
