Phase One, a developer of digital imaging technologies, has announced the P3 Payload, a versatile solution designed for fast, efficient and safe inspection of critical infrastructure with an unmanned aerial vehicle (UAV).
The P3 Payload includes a Phase One iXM 100MP or 50MP camera, one of the RSM lens options, and a new gimbal with integrated rangefinder.
Available in the second quarter of 2021, the P3 Payload is offered in two configurations to meet a wide range of user requirements.
The P3 for the DJI M300 is plug-and-play, developed mainly for operators and service providers that already own, or are considering purchasing, a DJI M300.
The P3 MAVLink is ready for integration with drones based on the open-source MAVLink protocol, and suitable for bundling by OEMs and solution integrators.
“The P3 addresses the unmet need for a high-quality, integrated imaging solution for inspection of critical assets where capturing the details is of paramount importance,” said Michael Messerschmidt, portfolio director for drones and inspection. “The P3 Payload is designed specifically for aerial drone inspection of diverse infrastructure where every flight — and every shot — must count.”
The centerpiece of the payload is the customer’s choice of Phase One iXM 100MP or 50MP camera. Robust and waterproof, these sensors feature a dynamic range that guarantees sharp image collection in high-contrast or low-light environments. The variety of lens options ensures large surface areas can be captured with millimeter-level detail, even at safe distances from the asset. The new gimbal with the integrated laser rangefinder ensures precise and fast focusing on every shot, eliminating blurry and out-of-focus images.
The P3 Payload is suitable for these inspection applications:
High-value assets. Bridges, dams and energy facilities where the value of the structure itself is high and the demand for frequent, accurate and detailed data is critical.
High-risk assessment. Electric transmission lines, oil refineries and other complex sites where inherent danger requires high-resolution inspection from a distance that is safe for the structure, the drone and personnel.
Time-critical assets. Wind turbines, offshore oil rigs, and other facilities where inspection windows are limited, and every UAV flight must successfully capture the required information.
“We developed the P3 Payload for cost-effective, productive operation so that large surface areas can be covered in fewer images, significantly shortening the mission time,” Messerschmidt said. “More importantly, the P3 can be operated with minimal risk to the asset and ground crew.”
Tallysman Wireless is offering two new VeroStar marine antennas to its line of GNSS products. The VSP6037L-MAR supports the full GNSS spectrum and the VSP6337L-MAR supports GPS/QZSS-L1/L2/L5, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b, BeiDou-B1/B2/B2a, and NavIC-L5 signals. Both antennas support L-band correction signals.
Marine vessels often host both Iridium (1616–1626.5 MHz) and Inmarsat (uplink: 1626.5–1660.5 MHz) satellite communication antennas that transmit and receive signals. The VSP6037L-MAR and VSP6337L-MAR VeroStar marine antennas strongly attenuate interference from both signal sources, providing 75 dB to 85 dB of attenuation over Iridium and 85 dB to 95 dB over Inmarsat uplink, enabling clean GNSS signal reception and precise positioning.
Every VeroStar antenna features a robust pre-filter and a high-IP3 LNA architecture, minimizing de-sensing from high-level out-of-band signals, including 700 MHz LTE, while still providing a noise figure of only 1.8 dB.
VeroStar antennas provide the best-in-class low elevation angle tracking of the full GNSS spectrum and L-band correction signals. The wideband spherical antenna element enables VeroStar antennas to deliver ±2 mm phase centre variation (PCV), making them suitable for high-precision marine, positioning and machine control applications.
The VeroStar marine antennas are housed in a rugged and compact enclosure that supports 1-inch pipe thread or 5/8-inch-11 TPI mounting and provides a TNC antenna connector. The antennas have also obtained the stringent IEC 60945 and IEC 61108 marine certifications, making them suitable for challenging marine environments.
Microchip Technology has integrate its BlueSky technology signal-anomaly detection software into its SyncServer S600 Series network time server and instruments.
The SyncServer S600 Series now provides GPS jamming and spoofing detection and protection, in combination with local radio frequency (RF) data logging and analysis. The SyncServer S600 Series Stratum 1 instrument, along with the BlueSky technology’s intelligent jamming and spoofing detectors, continuously monitor local GPS constellation health and examine GPS and local RF signal integrity to assure validity.
If an anomaly is detected, the solution sends an alarm and, if necessary, the SyncServer instrument can be shifted to alternative time sources or an internal oscillator. This protects ongoing timing outputs while ensuring only minimal, predictable timing degradation to vital network and business operations in applications ranging from banking and stock trading to electric utilities and aerospace and defense.
The SyncServer BlueSky technology, which provides continuous detection and protection against GPS jamming and spoofing. includes a comprehensive suite of logging, charting and measuring tools to characterize local GPS satellite signals as well as local RF events over time.
This can help enable correlating, troubleshooting, identifying and correcting local anomalies, some of which may be related to consumer electronics, or nearby RF signal broadcasts. The solution is optionally available through the SyncServer v4.1 software release that provides a selection of features found in Microchip’s BlueSky GNSS Firewall solution for third-party GPS receivers and critical infrastructure.
In separate letters to members of the House of Representatives and the Senate, seven companies and a non-profit urged Congress to support alternative positioning, navigation and timing systems (PNT) with the “necessary funds and other appropriate policy tools.”
The letters focus on and endorse the system-of-systems approach outlined in the Department of Transportation’s (DOT) recent report to Congress on the results of its GPS Backup Technology Demonstration. The report found an adequate and robust American PNT system should include space-based L-band signals, low-frequency (LF) and ultra-high-frequency (UHS) signals, and fiber connections between the terrestrial LF and UHF transmitters.
“Our country depends on GPS for critical infrastructure, and there is an urgent need for resiliency being built into our critical infrastructure. Before the report came out, some of us had different ideas of how the U.S. should go forward,” said Ganesh Pattabiraman, CEO of NextNav. “But the DOT report provided the data to make it very clear that it is a combination of technologies that need to come together to truly enable nationwide backup to GPS, and it was good to see we could get industry alignment on the findings.”
The letters describe many of the threats to GPS, both natural and malicious; its vulnerabilities; and the dire consequences of disruptions. They go on to state that robust, more reliable PNT is needed for emerging and future systems like E911, 5G, resilient electrical grids, drones and other automated systems.
Monty Johnson, CEO of OPNT, a provider of time-over-fiber services, praised the findings of the DOT report. “The key to resilience and reliability in a system-of-systems is including technologies that deliver the same information using starkly different means. It is hard to imagine a combination of technologies that are more diverse than fiber, satellites, LF and UHF.”
According to Pattabiraman, the signers of the letter agree that the DOT report made clear that there are mature technologies available today that can address the GPS backup issue. DOT and Congress now have the data to act to enable a much-needed resilient infrastructure for the country.
Dana A. Goward, president of the non-profit RNT Foundation, agreed. He also observed that deciding on the technologies and congressional funding were important, but only first steps. “The goal of this effort is not to just implement systems,” he said. “it’s to make America safer. Establishing the services quickly and efficiently will be key, as will ensuring they are widely adopted.”
“Protecting the nation from the consequences of a space-based PNT disruption will require that these systems be accessed and used by a wide variety of users from first responders and delivery services, to all forms of critical infrastructure,” Goward said. “This means the government will need to eliminate as many barriers to adoption as possible. One or more of these alternatives has to be available to every American. And a basic level of service has to be free, just like the GPS utility it is reinforcing. Fortunately, we estimate this can be done relatively inexpensively. It will be only a small fraction of the $1.7B we spent on GPS last year.”
The alternative to making this relatively modest investment, according to Goward, is unacceptable.
“There are lots of threats to GPS,” he said. “Take the sun for example. The most recent study I saw estimates a 70% chance solar activity will damage the GPS constellation in the next 30 years and a 20% chance it will destroy a big part of it. And the sun is just one of the threats we face. We can’t keep playing this kind of Russian Roulette with the fate of our nation. Especially when other countries like Russia and China have already taken steps to protect themselves with terrestrial systems.”

A 2020 explosion in Lebanon’s port city of Beirut led to a southward-bound, high-velocity atmospheric wave that rivaled ones generated by volcanic eruptions.

Just after 6 p.m. local time (15:00 UTC) on Aug. 4, 2020, more than 2,750 tons worth of unsafely stored ammonium nitrate exploded in Lebanon’s port city of Beirut, killing around 200 people, making more than 300,000 temporarily homeless, and leaving a 140-meter-diameter crater in its wake. The blast is considered one of the most powerful non-nuclear, man-made explosions in human history.
Now, calculations by Hokkaido University scientists in Japan have found that the atmospheric wave from the blast led to electron disturbances high in Earth’s upper atmosphere. They published their findings in the journal Scientific Reports.
The team of scientists, which included colleagues from the National Institute of Technology Rourkela in India, calculated changes in total electron content in Earth’s ionosphere: the part of the atmosphere from around 50 to 965 kilometres in altitude. Natural events like extreme ultraviolet radiation and geomagnetic storms, and man-made activities like nuclear tests, can cause disturbances to the ionosphere’s electron content.
“We found that the blast generated a wave that travelled in the ionosphere in a southwards direction at a velocity of around 0.8 kilometres per second,” says Hokkaido University Earth and Planetary scientist Kosuke Heki. This is similar to the speed of sound waves travelling through the ionosphere.
The team calculated changes in ionospheric electron content by looking at differences in delays experienced by microwave signals transmitted by GPS satellites to their ground stations. Changes in electron content affect these signals as they pass through the ionosphere and must be regularly taken into consideration to accurately measure GPS positions.
The ionospheric disturbance caused by an explosion can be detected by differential ionospheric delays of microwave signals of two carrier frequencies from global navigation satellite system (GNSS) satellites. (Image: Bhaskar Kundu, et al. Scientific Reports. Feb. 2, 2021).
The scientists also compared the magnitude of the ionospheric wave generated by the Beirut blast to similar waves following natural and anthropogenic events. They found that the wave generated by the Beirut blast was slightly larger than a wave generated by the 2004 eruption of Asama Volcano in central Japan, and comparable to ones that followed other recent eruptions on Japanese islands.
The energy of the ionospheric wave generated by the Beirut blast was significantly larger than a more energetic explosion in a Wyoming coal mine in the USA in 1996. The Beirut blast was equivalent to an explosion of 1.1 kilotons of TNT, while the Wyoming explosion was equivalent to 1.5 kilotons of TNT. The total electron content disturbance of the Wyoming explosion was only 1/10 of that caused by the Beirut blast. The scientists believe this was partially due to the Wyoming mine being located in a somewhat protected pit.

First commercial deployment to be installed on a major turnpike used by tens of millions of vehicles every year
An electronic tolling system that uses high-performance lidar sensors from Cepton and a vehicle identification solution from Red Fox ID is expected to be deployed on a major highway turnpike crossing multiple states in the United States.
The turnpike project is expected to provide fast, accurate, real-time tolling to enable smooth traffic flows. Specifics of the project — including states involved and the timeframe of installation — were not disclosed.

Based on an extended collaboration with leading lidar solution provider Cepton, Red Fox ID — a designer and developer of vehicle identification and classification solutions — has developed a multi-lane, free-flow tolling system called Quantum, which is able to accurately detect, track and classify vehicles of any size or type at highway speeds.
Quantum uses Cepton’s Micro Motion Technology (MMT)-based Sora-P60 or Sora-P90 lidar sensors for high-resolution vehicle profiling, to enable integrators and road operators to achieve highly accurate customer billing in real time, with free flow, barrier-free tolling.
For tolls to be charged correctly based on vehicle class, traditional tolling systems often use tollbooths for manual processing or depend on vehicle speed-reduction infrastructure to allow for time to capture vehicle information. That can cause congestion, increased emissions and frustration among customers.
Advanced systems that aim to enable faster tolling are often subject to significant errors, such as missed vehicles or wrong vehicle classification, because of limitations of the sensors being used, such as cameras and weight-based ground sensors. Vehicle-classification errors can have significant operating cost consequences for tolling operators, while leakage leads to lower revenues. With tollways processing tens of millions of vehicles a year, the cumulative impact of inaccuracies and errors creates significant administrative costs, losses and customer dissatisfaction.
Red Fox ID’s Quantum solution adds an extra layer of accuracy to the tolling system by integrating Cepton’s lidar technology. A gantry-mounted system using Quantum is able to accurately detect and track vehicles even as they switch lanes. Quantum captures and extracts high-quality information, such as vehicle velocity, size and class. All of that information is used as input to a separate billing system to compute and apply the appropriate tolling charge.
Quantum can also direct camera-based systems on the gantry to capture a vehicle’s front and rear plates in the event that a transponder cannot be detected. Through these innovations, Quantum has demonstrated a vehicle-detection accuracy in all traffic conditions of 99.96%, an axle-classification accuracy in all traffic conditions of 99.9% and a vehicle-length accuracy of +/-5%. The system uses Cepton’s Sora-P sensor family which has been tested and proven during extended trials, including in various weather and light conditions.
The recently released Sora-P90 lidar features a 380-Hz frame rate to deliver 1140 line scans per second, providing high-fidelity profiling of vehicles passing at highway speeds. Powered by Cepton’s patented, rotation-free, frictionless and mirrorless MMT, the Sora-P90 is rugged, reliable and scalable, making it suited for automated tolling applications.With a 90° horizontal field of view, the lidar can be set up using one gantry instead of two separate sensors and gantries, making overall deployment more cost effective.
Red Fox ID has been working with Cepton on multiple trials and proof of concept projects across the globe since 2019. This has allowed both partners to expand the application of advanced lidar intelligence for high-accuracy tolling on highways and roadways in a growing list of countries, across North America, Europe, the Middle Eas, Africa and Asia.
“Our industry’s drive for overhead tolling solutions has failed to materialize in the mainstream due, primarily, to a lack of sensors capable of achieving the high levels of accuracy required for a modern tolling product,” said Steve Bird, CEO of Red Fox ID. “The technical innovations enabled by Cepton offer us new design options. Improvements in the resolution of the data, the ability to deal with the full range of weather-related conditions, and the development of a sensor with an in-service lifespan suitable for tolling make it possible, for the first time, for us to develop an accurate, overhead free flow system. Our partnership with Cepton will be a game-changer in revolutionizing the tolling market.”
“It is very clear that lidar’s uses extend far beyond just serving as the ‘eyes’ of autonomous vehicles,” said Jun Pei, CEO of Cepton. “Our lidar technology has a huge part to play in making our transport infrastructure smarter, safer, greener and more efficient, as we can see here following Quantum’s highly successful real-world testing. The key to success for toll operators and providers is minimal error and maximum yield, and we are excited to be partnering with Red Fox ID to help our mutual customers achieve this goal with our market-leading lidar technology. We look forward to working with them to expand our partnership worldwide.”
