Air taxi, hydrogen fuel cells and airships top UAV news

Looking around the industry over the last few weeks, there continues to be a flood of innovation that promises new approaches for unmanned aircraft in addressing several new opportunities. This month I cover a flying taxi at the 2019 Consumer Electronics Show (CES) in Las Vegas, greater range for multi-copters using fuel cells, a potential huge drone in the making, and a potential Florida controversy over use of a tethered aerostat — interesting stuff!

Bell Flying Car/Air Taxi

At CES of all places, there was a new idea for air-taxis — not yet a UAV, but with the promise of future autonomous flight, it surely deserves a mention. Bell brought its latest commercial vertical take-off and landing (VTOL) mock-up to CES to test the level of interest in its concept of a flying car.

Lift and directional flight control are provided by six 8-foot ducted fans, each driven by its own electric motor and powered by a turbine-driven electric generation and back-up battery system. Using technology derived from the mil-spec V-22 Osprey Tilt-Rotor and its commercial V-280 cousin, the ducted fans pivot from horizontal for take-off to vertical for forward flight.

The concept vehicle at CES had a seat for the pilot, but the digital flight control system is envisaged to have autonomous flight capability — and there we have another approach for a UAV flying car/air-taxi — from one of the mainstay aviation manufacturers of helicopters with all the necessary experience to make it happen.

Fuel-Cell-Powered UAV Flies for 70 Minutes

There’s apparently a new way to overcome the short duration that is currently available for flying existing multi-rotor drones — don’t just rely on batteries, use hydrogen! Actually a hydrogen fuel-cell configuration that has recently been tested in the UK to extend flight time to 70 minutes, while carrying a 5-kg payload.

The UK team includes Intelligent Energy, which supplies the fuel-cell, engineering firm Productiv, and UAS video company BATCAM, with funding provided by Innovate UK, a government-sponsored group that supports novel ventures such as this joint project.

Most existing battery-powered multi-rotor UAVs have endurance in the tens of minute (DJI seems to be approaching 20-30 minutes with some of its drone models). But longer endurance is really important for most operators, especially for capturing lengthy video, hence the interest and participation of BATCAM as the operator/consultant for the project.

Fuel cells provide a number of advantages over batteries with fast refuel, little vibration, quiet operation, zero emission at point of use, and around three times longer flight time. Intelligent Energy is making use of a portable hydrogen refueling system supplied by NanoSUN.

With BATCAM set to begin operational trials, the company is optimistic that further development of hydrogen fuel cells for UAVs will not only enable even longer video broadcasts but will solve the problem encountered with the difficult and expensive international transportation of Lithium polymer batteries.

Airship Moves towards Civil Certification

While we are in the UK, a huge 300-foot-long helium-filled airship called the Airlander 10 is again moving steadily down the path to gain civil approval by the Civil Aviation Authority (CAA), despite a previous crash in November 2017 due to a wayward landing cable.

The latest milestone was just achieved at the end of 2018 when CAA awarded Hybrid Air Vehicles Ltd. (HAV) a Production Organisation Approval, following on from earlier Design Organisation Approval by the European Aviation Safety Agency (EASA) in October 2018.

This behemoth airship is claimed to be the largest aircraft in the world, can carry 10 tons of cargo virtually anywhere on earth, stays airborne for up to five days, and can land almost anywhere. Powered by two forward-mounted rotating ducted fans and two aft fixed fans, all driven by diesel engines, the pressurized helium-filled envelope is 302 feet long, 143 feet wide, 85 feet tall, and has no internal support structures — all this with a cruise speed of up to 80 knots and a maximum altitude of 20,000 feet.

The Airlander is aimed at bulk cargo transport, but could also handle communication and observation/reconnaissance roles in both the military and commercial sectors. And it’s not so far away from becoming the largest unmanned aircraft in the world, either, should things eventually turn in that direction. Could there be potential for a greater payload without the extensive provisions for a pilot, with lower operating costs, potentially greater range and speed and/or operational altitude?

Miami Police use Tethered Aerostat

Miami police have been using a tethered aerostat to monitor large gatherings, such as the Dec. 28 Orange Bowl-related party called the Capital One Beach Bash. Presumably this use had a safety related motivation, and there was hopefully no intent to spy on partygoers.

However, I just became aware that police cannot fly drones in Florida to surveil people — there’s a law against it. But there is a provision in the Florida “Freedom from Unwarranted Surveillance Act,” which starts off: “If the law enforcement agency possesses reasonable suspicion that, under particular circumstances, swift action is needed to prevent imminent danger to life or serious damage to property,…”. Now, I’m no lawyer, but it would seem that this exclusion might possibly allow the Miami cops to monitor large gatherings where there might be a need to watch out for people’s safety – that generally being what we employ the police to do for us.

But the Florida lawmakers certainly believe that there is clearly a need to protect people’s privacy and to prevent unauthorized monitoring of an individual’s activities using drones. The provisions of Florida Statute 934.50 prohibits “the observation of such persons with sufficient visual clarity to be able to obtain information about their identity, habits, conduct, movements, or whereabouts” — a good thing to do to protect our freedom of movement and basic rights.

But you have to ask yourself if a general prohibition on the use of drones by police is the best thing to do when other police departments around the U.S. are gaining advantages from drone usage by speeding up and improving the accuracy of traffic accident investigations, for search and rescue, in crime scene reconstruction, for disaster response, and of course for improving officer safety — in fact, all the things that are already achieved through the use of police helicopters, but at a fraction of the cost.

Florida Statute 934.50 already has a significant number of allowable exceptions to enable a “law enforcement agency” and others to operate drones legally, but could it also be possible that these wider benefits of drone use might be fully exempted without infringing any personal liberties?

Conclusion

To sum up, we have a big aerospace company jumping in to help shape the future of unmanned air taxis; another drone fuel-cell application that significantly extends flight time; and progress towards certification of an airship that has benefits as a drone. Finally, police use of a tethered aerostat at an event stirs potential controversy, while other police forces benefit from the use of drones — a mixed bag of drone ventures that seem to have great potential.

Commentary: High-precision positioning is going mainstream

Guest column by Peter Fairhurst, Director, Product Line Management, Product Center Positioning, u-blox

A new generation of GNSS hardware and pioneering new correction data services are enabling cheaper, more compact and truly scalable high-precision GNSS solutions, ready for the mass market.

High-precision GNSS as employed by specialized markets for more than a decade isn’t aren’t suitable for mass-market autonomous vehicles or other mainstream use cases. As well as being big, heavy and expensive, traditional high-precision GNSS systems don’t scale, which is a critical shortcoming when you consider this capability may very soon need to be built into every car that gets built.

To overcome these challenges, we’re seeing two complementary things coming to market: a new generation of GNSS hardware, and pioneering new correction data services. These two key facets combine to enable cheaper, more compact and truly scalable high-precision GNSS solutions, ready for the mass market.

A new generation of GNSS correction service forgoes the two-way link between customer device and the correction data service that is a hallmark of traditional high-precision GNSS corrections. Instead of sending each device its own, location-specific GNSS correction data, the new-generation services create a real-time model of relevant errors across their entire territory. They broadcast this over satellite and/or the Internet for customer devices to pick up.

Transmitting modeled GNSS error data to receivers across an entire region – as opposed to maintaining a two-way link with each and every device – opens the door to large-scale, mass market applications of high-precision GNSS

The shortcomings of traditional high-precision positioning

Correction data has long been key to high-precision GNSS services. In traditional applications, the customer’s positioning device detects its approximate location and sends this information to its correction service provider. This provider uses a network of base stations to monitor GNSS errors, comparing the readings calculated from the satellite signals to the stations’ known, fixed positions. It uses these insights to send the customer’s device tailored correction data, based on its location.

The technology has successfully been used to provide centimeter-level accuracy in surveying, agriculture and machine control, but annual subscriptions of sometimes more than $1000 per device mean it’s remained confined to specialized markets.

Moreover, traditional correction data services typically only operate in one country, or even one state. While this may not be an issue in some applications (such as localized agriculture), there are other use cases where limited range is a major problem. Imagine, for example, that you regularly need to travel across a state or national boundary in your (semi-) autonomous vehicle, or carry out remote UAV-based surveying in another country: maintaining your high-precision positioning capability is likely to mean roaming contracts and other extra costs.

The other issue with these traditional services is scalability. They use two-way cellular communication to pass data back and forth between the customer device and the correction data provider. And while this works when device density is relatively low, if this number grew to thousands or even millions of end-user pieces of kit trying to access the correction data service, current cellular infrastructure would struggle to deliver the required reliability. Particularly in safety-critical applications, where losing access to the correction data service could put lives at risk, this is unacceptable.

Recent developments in high-precision positioning

The new generation of GNSS correction services, creating and broadcasting a real-time model of relevant errors across their entire territory, over satellite and/or the internet for customer devices to pick up, opens the door to large-scale, mass-market applications of high-precision GNSS. Technology using State Space Representation (SSR) is one flavor of these new-generation GNSS correction data services.

Japan has led the way in GNSS error-broadcasting, using the L6 signal of its QZSS satellite network as a proving ground for mainstream use of the approach. Although it’s currently only available within Japan, the Centimeter Level Augmentation Service (CLAS) is generating a lot of interest across the automotive, agricultural and machine-control industries. Mitsubishi Electric, for example, used the CLAS service to field-test its autonomous driving system.

In China, Qianxun Spatial Intelligence Inc. is pioneering a different technique. Instead of broadcasting the data, Qianxun SI is leveraging its special access to the Chinese GNSS reference base stations to push the boundaries of what’s possible using the traditional technique. It provides tailored correction data services to customers including individuals, system integrators and original equipment manufacturers (OEMs). While it’s been a success in China, the approach is less appealing to OEMs who ship worldwide, because it requires their clients to arrange their own, local GNSS correction data.

Another important advance has been the rise of multi-band GNSS receivers, which enhance standalone positioning accuracy, thereby delivering a better customer experience in a variety of use cases. However, even multi-band receivers can’t achieve the centimeter-level accuracy that mobile robotics and autonomous vehicles need: these devices will always need to be complemented by some form of correction service.

Continent-wide GNSS correction data

Particularly in Europe, where there’s a lot of cross-border travel and economic activity, the simplicity of continent-wide GNSS correction services would offer enormous value. Sapcorda, for example, a recently launched joint venture between Bosch, Geo++, Mitsubishi Electric and u-blox, is creating a next-generation GNSS correction data service with coverage on a global scale (Europe, North America, etc), building on the lessons learned in Japan.

Sapcorda will broadcast right across the continent, using cellular networks as well as over satellite links. Customers won’t be tied to a specific GNSS manufacturer. Data will be distributed in an open format, so that device-makers can create exactly the solutions their customers want.

Having access to GNSS correction services continent-wide has the potential to transform high-precision positioning into a mainstream offering, supporting various IoT applications, as well as drones and (semi-) autonomous vehicles.

Addressing the remaining challenges

High-precision GNSS correction services that target the mass market are still relatively new, with different suppliers pursuing different business models. Trimble’s service, for example, doesn’t use an open correction-data format, and is only compatible with devices using its own GNSS receivers. The benefit of this is that it can deliver a seamless, fully integrated solution, with complete interoperability across the Trimble product range (provided the region in question has good coverage). OEMs with customers is geographically broader markets will need to weigh this up against the benefits of global coverage provided by a range of correction-data suppliers offering open-format data.

As we touched on earlier, in safety-critical applications where location-accuracy is essential, any correction data service must be up to the task. This includes ensuring data broadcasts aren’t crowded out when cellular networks become saturated. To this end, u-blox has been working with the 3GPP body to create appropriate standards that can ensure the service meets the required service level agreements.

Lastly, although there’s now country-wide coverage in both China and Japan, Sapcorda is now attempting to provide continent-wide high-precision services. If it’s a success, it could overcome the challenges of national boundaries and country-based cellular providers. It’s as yet unclear how existing correction-data-service suppliers will respond.

Customer satisfaction is paramount

For high-precision GNSS services to achieve mainstream success, they not only need to offer wide coverage and be truly open, but must facilitate innovation and ensure they can broaden the appeal of this capability beyond being a niche specialism. Like in any industry, customer satisfaction is essential if the technology is to achieve this.

Complexity that arises as a result of state boundaries, national borders, conflicting regulations or subscriptions, must be shielded from the end user and dealt with upstream. This is already happening in some areas, where device-makers are partnering with correction data service providers, enabling them to bundle the service cost into the device cost that the end user pays.

A revolution in positioning

As well as helping to realize some of the automated navigation solutions currently under development, new-generation high-precision GNSS services are driving a seismic shift across the whole industry.

The rise of innovative, high-precision GNSS technology, combined with business models that promise to make high-precision a mass market reality, mean the coming years will be tremendously exciting. By disrupting the existing market, the new technology will mean lots of new opportunities for those ready to grasp them.

Allystar launches multi-band, multi-GNSS chip for devices

Image: Allystar

Allystar Technology Co. Ltd. has launched a multi-band, multi-GNSS system on chip, the HD8040 series, to help portable devices save size and weight. The HD8040 offered in wafer-level chip-scale packaging (WLCSP).

The HD8040 series of chipsets fully supports all civil signals on the L5 band, said Shi Xian Yang, Allystar high-precision product manager at Allystar. Besides GPS, other constellations with L1/L5 signals include Galileo, BeiDou, the Indian NavIC system and Japanese QZSS.

Besides L1 band, HD8040D supports L5/B2a/E5a signals, which are expected to have lower noise and be better in multipath mitigation mainly due to the higher chipping rate of L5 signals relative to L1 C/A code.

HD8041D supports IRNSS (NavIC), which makes it suitable for navigation in urban areas in India and the Middle East, where seven NavIC satellites have a higher elevation than both GPS and Galileo satellites. This means IRNSS (NavIC) would provide greater accuracy, precision and available measurements.

With the features of small size (3 x 3 millimeters) and low power consumption, the HD8040 series is suitable for smartphones, tablets and other portable devices.

The architecture integrates floating-point arithmetic units based on ARM CortexM4, 160 KB RAM, 32 KB backup RAM with VBAT, and 384 KB embedded Flash memory. Besides basic peripheral interfaces UART, I2C, SPI and GPIO, it supports the CAN interface for automotive applications, too.

Customer samples of the HD8040D and HD8041D are available now.

Regulus Cyber miniaturizes anti-spoofing GNSS receiver

Photo: Regulus

Regulus Cyber is showcasing its anti-spoofing GNSS receiver at the Consumer Electronics Show, being held Jan. 8-11 in Las Vegas.

Previously introduced in our Launchpad feature, the Regulus Cyber solves GNSS spoofing attacks that threaten the automotive, aviation, maritime and mobile industries with a unique technology applicable both as a fortified GNSS receiver, capable of detecting spoofing attacks, and at the chip level, allowing mobile phones, cars and internet of things (IoT) devices to receive GNSS spoofing protection for the first time, the company said.

The company was able to miniaturize its technology into a form factor that provides customers more flexibility with integration.

The Regulus Pyramid GNSS Receiver is a fully functional GNSS receiver, fortified with the spoofing detection capability. The receiver contains patented technology that enables it to differentiate between real GNSS signals and fake ones generated by an attacker.

The Pyramid GNSS receiver is a direct replacement to any automotive GNSS receiver. The upcoming chip-level technology offers both spoofing detection and spoofing mitigation to any GNSS-based device, including mobile phones, the company added.

The Spoofing Problem. Any vehicle guided by a GNSS system can be spoofed using open-source software and a software defined radio (SDR) legally purchased from Amazon for under $300. A spoofer can generate and transmit fake GNSS signals that can be used by the vehicle’s navigation system to calculate a false destination, directing the vehicle to an entirely different location, a potentially life-threatening hazard.

In addition, spoofing is a growing concern to any application or device that uses satellite positioning, navigation or time. While real attacks are expanding, anti-spoofing solutions remain a luxury that only high-end, defense markets can afford.

While current solutions are big, heavy and expensive, Pyramid GNSS offers industry-standard size and price. Industries such as automotive, aviation, maritime, and mobile phones can defend themselves against this sophisticated emerging threat, at an affordable price and relevant size, power consumption and weight, the company said.

“We designed our product to be a fraction of the size that is currently available on the market so that all types of companies – whether it is a car manufacturer or telecom provider relying on GNSS – can integrate it seamlessly,” said Yonatan Zur, CEO of Regulus Cyber. “GNSS spoofing will need to be a major security focus during 2019 since it leaves so many industries vulnerable to attacks.”

To meet Regulus Cyber at CES, visit booth #2602 at the Westgate.

Antenova’s Raptor antenna pinpoints location to within centimeters

Photo: Antenova

Antenova Ltd. has developed a new positioning antenna that it says can pinpoint a location to within centimeters in the GNSS bands. Antenova is a manufacturer of antennas and RF antenna modules for machine-to-machine and the internet of things.

Antenova will be showing samples of the Raptor antenna at the Consumer Electronics Show, being held Jan. 8-11 in Las Vegas, in booth #2220 in the Westgate hall.

The Raptor antenna utilizes the L2 1200-MHz satellite band that recently became available for civilian use.

The addition of the L2 frequency band combines multi-band satellite signal reception and GNSS correction data. This helps to mitigate position errors, greatly improving accuracy, especially in urban areas, the company said.

As well as improving tracking, the L2 band is beneficial for UAVs, drones, autonomous vehicles, agriculture, grid mapping and other emerging applications, Antenova added.

The antenna is the latest addition to Antenova’s lamiiANT range of rigid FR4 antennas which are designed for easy insertion onto a printed circuit board (PCB).

The antenna itself is very small. It is a GPS single-feed antenna in surface mount (SMD) form, measuring 16.0 x 8.0 x 1.6 millimeters, suitable for small PCBs within all kinds of small electronic devices.

“This is an outstanding antenna, because it achieves the same precision as a much larger, heavier ceramic patch antenna, but in a very compact SMD part,” said Colin Newman, CEO of Antenova. “A ceramic antenna would need to be 35 x 35 millimeters to achieve a similar level of accuracy and performance.” Raptor is supplied in tape and reel for ease in high-volume manufacturing applications.

Septentrio and Sapcorda to demonstrate GNSS positioning for autonomous driving

Septentrio, a high-precision GNSS company, and Sapcorda, a specialist in GNSS correction services, will conduct a live demonstration of a safe, high-accuracy positioning and correction solution for automated driving.

“We are running the demonstration during the course of this week just south of Las Vegas city center,” Neil Vacans told GPS World. Vacans is Septentrio’s vice president of global Sales. The demonstration is taking place in Las Vegas during the Consumer Electronics Show, being held Jan. 8-11.

Sapcorda and Septentrio have put together a solution that is ready for demonstration in Europe and North America.

The companies have combined their respective technologies to deliver the benefits of SSR (space state representation) technology seamlessly to OEM automakers and Tier 1 integrators. These benefits include decimeter-accuracy within seconds, anywhere over an entire continent, to support autonomy levels from lane keeping to full autonomy in a totally homogeneous coverage, the companies said.

The GNSS augmentation service is scalable through simple broadcast corrections, and safety-awareness is provided via Sapcorda’s integrity concept and Septentrio’s integrity monitoring engine.

In December 2018, Septentrio announced its mosaic compact multi-constellation GNSS receiver SiP (system-in-package) module, available in 2019. The Septentrio mosaic, a multi-band, multi-constellation receiver in a low-power surface-mount module with a wide array of interfaces, is designed for mass-market applications like robotics and autonomous systems. The mosaic module integrates the latest GNSS and RF ASIC technology, as well as the robust positioning engine from Septentrio.

All Septentrio GNSS receivers and modules feature AIM+ technology, an advanced on-board interference mitigation commercially available. Septentrio GNSS receivers can suppress the widest variety of interferers, from simple continuous narrowband signals to the most complex wideband and pulsed jammers.

“We are excited to be able to provide live demonstrations of Sapcorda’s safe and precise correction service especially designed for autonomous driving,” said Jan Van Hees, business development director at Septentrio. “Sapcorda provides a unique high-precision GNSS correction service designed for fast, homogeneous accuracy at continental coverage, thus ideal for autonomous and mass market applications.”

“Septentrio specializes in high-precision and high reliability GNSS positioning for a variety of industrial and commercial markets,” said Goran Jedrejčić, business development manager at Sapcorda. “They have developed a range of technologies, including unique jamming robustness and integrity positioning to support safety-sensitive applications in various challenging environments. Combining this with our safety-centered correction service, it is a unique solution for developers of autonomous driving systems.”

“With fast and efficient implementation of Sapcorda SSR-based correction service into Septentrio’s GNSS-platform, we were able to demonstrate the efficiency of the technology for automotive use in a robust & highly efficient way,” confirmed Jedrejčić. “Septentrio offers a unique blend of GNSS-based technologies and is an ideal partner for both traditional and new markets, with growing demand for high-precision positioning.”

Dual-band GNSS market moving from insignificant to billions in less than 5 years

After many years of development at the fringe of the GNSS industry, dual-frequency GNSS devices are finally ready to hit the mass market and will account for more than a billion chipset shipments in 2023, according to a new market data report by ABI Research.

ABI Research is a market-foresight advisory firm.

The report finds that the bulk of this growth will come from the adoption in the smartphone market with consumers hungry for better location accuracy.

Dual-band GNSS can mitigate the multipath interference effects, which are especially present in areas with a high density of buildings, like urban canyons, and deliver significantly higher accuracy than single-frequency devices.

However, several obstacles prevented widespread adoption of dual-band GNSS until now, including insufficient satellite coverage of a second band, which could be L2 or L5/E5, high chipset prices, and challenges in fitting these integrated circuits and related antennas into small devices such as smartphones.

“On the availability side, this year has seen several satellites launched into orbit every month, most of them fitted with L5/E5 capabilities, and the Chinese and European Union governments plan to have their satellite constellations fully operational by 2020. L5/E5 devices will not be left in the dark,” said Henrique Rocha, a research analyst for Location Technologies at ABI Research.

Furthermore, new breakthroughs from key chipset manufacturers are disrupting this market by overcoming the barriers to mass dual-frequency adoption. With Location-Based Services (LBS) applications in mind, Broadcom has released the BCM47755 dual-band location hub, claiming the system’s architecture achieves the synergistic benefits that cannot be reached by multiple integrated circuits (ICs), thereby reducing its overall size and power consumption.

Other important players in this market have also come forward with dual-frequency solutions, including Qualcomm with the Snapdragon X24 LTE modem and HiSilicon with the Kirin 980 system-on-a-chip. Both attribute their superior energy efficiency and form factor to intelligent data processing and a FinFET transistor design. Other chipset manufacturers such as MediaTek are expected to follow suit and present their own dual-band products for LBS.

At the consumer level, considering the handset market is the largest GNSS segment, accounting for 85 percent of all GNSS chipset shipments in 2018, the launch of the dual-frequency Xiaomi Mi 8, Xiaomi Mi Mix 3 and the Huawei Mate 20 following such breakthroughs in the chipset industry is a significant development because it opens a new lane of competition between smartphone manufacturers.

It is expected that dual-frequency devices will dominate the high-end smartphone market in a matter of a few years, and by 2023 dual-band GNSS ICs will comprise 36% of total GNSS LBS IC shipments worldwide.

Triple-frequency chips. In other significant markets for multi-frequency GNSS, such as surveying and automotive applications, triple-frequency chipsets are being released, including STMicroelectronics’ TeseoAPP and u-blox’s F9. Adding a third frequency allows for better noise correction and higher accuracy compared to dual-frequency.

ABI Research believes that triple-frequency devices will see, at least for now, a relatively shy adoption as manufacturers will need to justify the cost and overcome the power issues they tackled for dual-frequency devices.

“For LBS the comparatively small accuracy gain going from dual- to triple-frequency GNSS is not worth the extra effort — for now. However, we will probably see triple-frequency GNSS take off when cars fitted with advanced driver assistance and autonomous driving systems begin to ship in large quantities,” added Rocha.

With full satellite operability of the main GNSS bands on the horizon and chipset manufacturers overcoming past hurdles for implementing dual-frequency solutions, it is likely a matter of time before most major companies in the segment scramble for a piece of this promising market. OEMs now need to show customers that dual-frequency GNSS can indeed deliver the accuracy they have promised so new location use cases can be sustained and introduced to the market.
