OEM devices are an integral part of many applications requiring precise positioning technology. As the OEM market grows and performance requirements become more demanding, it is critical for OEM devices to be reliable, accurate, and easy to integrate. From precision agriculture, to surveying and mapping, to UAV missions, there are OEM devices on the market suitable for demanding applications.

Survey and Map Like a Pro

Surveying and mapping is one area in which OEM boards are embedded deep in many products. Septentrio designs and manufactures multi-frequency, multi-constellation, GPS/GNSS positioning technology and offers a variety of OEM products for demanding applications.

The AsteRx-m3 Pro is an ultra-low power GNSS rover receiver. It is compact and high-performance, making it suitable for integration into high-precision industrial applications. It incorporates multi-frequency, multi-constellation GNSS technology as well as anti-jamming algorithms for availability and reliability. The AsteRx-m3 Pro features AIM+ advanced anti-jamming and anti-spoofing technology as a part of Septentrio’s GNSS+ Technology Suite.

This receiver is designed for rover (mobile) applications, making it an easy-to-integrate solution for any kinematic application where reliable high-accuracy positioning is needed. It is available in single or dual antenna mode, for high quality heading and pitch, or heading and roll information.

GNSS heading is available directly from initialization and removes reliance on vehicle dynamics or magnetic sensors. This is an optional feature.

“Septentrio OEM receivers come in a variety of form factors, from compact modules to credit-card boards,” Danilo Sabbatini, OEM product manager at Septentrio, stated. “Our multi-frequency OEM receiver portfolio includes products that fit various user needs from purely rover GNSS high accuracy positioning to heading receivers, as well as GNSS/INS boards for inertial navigation or mapping.”

Aside from surveying and mapping, the AsteRx-m3 Pro is suitable for assured position, navigation and timing (PNT), autonomous vehicles, precision agriculture, logistics and port operations, mining and construction, rail, robotics, space and UAV applications.

Plowing the Way

The increase in demand for food due to population growth challenges farmers to increase production. To help them do this, Septentrio is working with manufacturers of agricultural machinery to enable them to achieve centimeter-level positioning accuracy.

The AsteRx-i3 D Pro is a ready-to-use GNSS/INS single-board receiver that delivers reliable centimeter-level positioning combined with 3D orientation (heading, pitch and roll) in demanding environments. Its inertial sensor provides orientation and positional dead-reckoning, making it suitable for systems that require continuous positioning even during short GNSS outages. It provides reliable and accurate positioning by enhancing GNSS with an inertial measurement unit (IMU).

The AsteRx-i3 D Pro is quad-constellation and multi-frequency. It provides all-in-view real-time kinematic positioning and features AIM+ unique interference monitoring and mitigation system and other advanced GNSS+ algorithms.

Like the AsteRx-m3 Pro, the AsteRx-i3 D Pro is also suitable for assured PNT, autonomous vehicles, logistics and port operations, mining and construction, rail, robotics, space, survey and mapping, and UAV applications.

Flying High

SBG Systems has released Ekinox Micro, a compact and rugged high-performance inertial navigation solution designed to deliver accuracy in challenging environments. Ekinox Micro combines a high-performance MEMS tactical inertial sensor with a quad-constellation, dual-antenna GNSS receiver, making it suitable for mission-critical applications.

GPS World caught up with Yoann Plénet, head of products at SBG Systems, at AUSVI XPONENTIAL in May. He elaborated on Ekinox Micro’s key markets and features.
“This is Quanta Micro in a box with the same performance and the same benefits that you get [with the Quanta Micro]: inertia, enhanced GNSS, and complement[ing] the GNSS,” Yoann said. “At the same time, we are targeting very rough environments, especially larger drones which are most likely military ones. So, [Ekinox Micro] is a very rugged product.”

Ekinox Micro includes pre-configured motion profiles for land, air and marine applications, enabling the sensor and algorithms to be tuned for maximum performance in any condition. The device is designed for ease of use and integration, with simple connectors, a web configuration interface, a datalogger, Ethernet connectivity, a PTP server, a REST API for configuration, and multiple input and output formats.

Ekinox Micro is compatible with real-time kinematic (RTK) and based on a tactical 0.8°/h class inertial measurement unit calibrated across the entire operating temperature range. It features accuracy roll/pitch of 0.015°, accuracy heading of 0.035°, and accuracy position of 1.2 m without any corrections or 1 cm in RTK.

Yoann also said that with the rise of jamming and spoofing, Ekinox Micro is designed with enhanced technology to mitigate those threats.

“Jamming and spoofing is ongoing and is an issue for more and more of our clients. So, we have worked a lot — and that is something that is beneficial to all of our product ranges — on enhancing our algorithms and our technology so we can better detect jamming and spoofing than we could before,” Yoann said.

Ekinox Micro will be commercially available in September. Click here for more information on Ekinox Micro.

Bonus Device

The Septentrio mosaic-X5 is a multi-band, multi-constellation GNSS receiver in a low power surface mount module with a wide array of interfaces. It is designed for mass market applications such as robotics and autonomous systems — capable of tracking all GNSS constellations, supporting current and future signals.

The mosaic-X5 has an update rate of 100 Hz, is easy to integrate, and is optimized for automated assembly.
Antoon De Proft, Septentrio’s CEO, mentioned in the April 2023 issue of GPS World the company’s innovation in Leuven, Belgium.

“Septentrio’s 20 years of experience in GNSS technology as well as our strategic partnership with the European Space Agency and close collaboration with the IMEC semiconductor technology hub has enabled us to produce the mosaic-X5 receiver,” he said. “This compact module is one of the highest performing and resilient GNSS receivers on the market. It is used in a wide array of applications, especially where the position is mission critical. Examples include a wide variety of autonomous devices, including drones that benefit from mosaic’s lightweight and low-power design.”

Francois Freulon, head of product management, added, “Reliability and resilience to GNSS vulnerabilities is a key pillar on which we base our receiver design. RF interference in the form of jamming and spoofing* is increasingly common, which is why we are investing heavily in securing our receivers at the core with the latest hardware and software techniques. In addition to the AIM+ patented technology, the mosaic module already includes OSNMA functionality, which will offer end-to-end authentication on Galileo’s civilian signals, protecting receivers from GNSS spoofing attacks.”

The U.S. government has visibly and physically conveyed its interest in getting air taxis into operation, through a visit of 70 people — attached to the newly formed Advanced Air Mobility (AAM) Coordination group — to Archer Aviation. The group talked with the executives of the company developing the “Midnight’ air-taxi aircraft and watched a flight test.

The AAM group includes members from leading government agencies concerned with making and keeping this segment of aviation successful, including the Federal Aviation Administration (FAA), the Department of Transportation (DOT), the National Aeronautics and Space Administration (NASA), the Department of Defense (DOD) and other agencies.

Gathering the views of Archer and other electric vertical takeoff and landing (eVTOL) developer executives should be an essential part of the AAM group’s information collection task. And while it’s great to see that the interagency group has every intention of promoting the AAM concept of air taxis, it would perhaps be better if the group also had access to representatives of manufacturers, developers, and those with UAS experience. It’s clear that we need to start by spreading the word, but also by including people in the group who have dedicated themselves to bringing these capabilities to market — that may make the process more efficient.

Along the way, it may also help to understand that the processes we have used in the past to get airframes like this into passenger carrying operations might not work well with this new industry. It’s understandable that it should take a lengthy period to assess, verify, qualify and certify such vehicles in the name of safety, but if companies run out of cash and fold in the interim — which is highly likely with this “start-up industry” — then shouldn’t we be looking for a better way to get these guys off the ground?

No one wants safety to be sacrificed, but could there be some way to streamline, speed up, or simplify the process without skipping essential steps — a way to get new technology into use before it’s obsolete, or a lack of start-up money dooms its progress? The forecast for the economy in the near future is in the billions of dollars. So, providing funding to improve the current processes does make sense. DOD has started to put serious effort into speeding up its acquisition process and has empowered the Defense Innovation Unit (DIU) to find quicker ways to bring commercial technologies into defense.

The processes used to bring new technologies into use are tried and proven, but they are lengthy. In defense, if our opposition can field things quicker than we do, they have an edge in strategy, tactics and a higher probability of winning in battle. These countries are using the same approaches in the commercial world too, and we need to be wary that they may also have a greater chance of winning the “economic war.”

Nevertheless, Archer in California and others such as Joby, also in California, and Liliam in Germany, plod on through varying stages of FAA and European Union Aviation Safety Agency (EASA) certification paths. An example of the effort that a company has been required to put into fulfilling the requirements of a certification agency is that of Lilium, which first applied for its Design Organization Approval (DOA) in 2017, is still churning through the qualification efforts and does not expect approval until 2025. Of course, the answer is “Don’t get on the certification ‘hamster-wheel’ unless you can stand the journey.” However, we do want these systems and vehicles to make it in order to overcome some of the traffic nightmare that we are living through in our major cities and to contribute to the growth in the economy.

Meanwhile, the great hope (even expectation) of the “flying car” is being kept alive by Doroni in Miami with its two seat H1 eVTOL. Having largely burnt through its $3.6 million StartEngine launch money, Doroni is looking for its second round of funding to build more prototypes and join the certification race. However, other single seat eVTOL flying cars have taken the easier route to certify under the FAA Ultralight category.

The H1 has semi-autonomous capability, which Doroni claims will make its eVTOL easy to fly, and allow general sales to any car driver. With air bags, an aerodynamic fuselage — which generates lift — 10 independent propulsion systems (four double prop ducted fans and two forward thrust props), an airframe that can behave as a parachute and “dissipate energy” in case of a crash, and landing gear, the H1 also has multiple independent batteries — all aimed at safety, which will help make it through certification verification. So, if you happen to have the $250,000 proposed sale price and are willing to wait on the completion of FAA certification, you could own your own “flying car.”

Doroni just announced that they have already made 50 test flights within their manufacturing facility along that test and qualification road.

---

Meanwhile, Ryse Aerotech in Ohio, recently demonstrated a manned test flight of its single seat Recon eVTOL — billed as an aid to farmers, with a top speed around 58 mph, a range of about 25 miles and with the right FAA clearance it could even reach an altitude of 700 ft — an airborne ATV for inspecting crops and the like.

The path to market that Ryse has selected, however, should see more vehicles in earlier use than Doroni’s H1. All you may need is a driver’s license to take off in a Recon because it’s qualified as an Ultralight craft — just buy and fly. Beware, you cannot fly anywhere near an airport or after dark. FAA has restrictions on Ultralight craft.

So, progress on the semi-autonomous “flying-car” front and a plea to consider the economic benefits and to look to how to improve the efficiency of the existing certification process — not a request to cut corners, rather a request to speed up the processes and save this start-up industry before it goes broke.

The products and services offered by Inertial Labs cater to a wide range of applications, including unmanned systems, defense, aerospace, transportation and more.

“We are extremely proud to have been awarded a GSA Schedule contract,” Jamie Marraccini, CEO of Inertial Labs said. “We look forward to supporting the critical missions of our government partners and providing them with the advanced technology they require.”

The ocean off the Gulf of Mexico is undergoing a marine heat wave that could pose a threat to coral reefs, as water temperatures reach 90°F. A coral reef watch map, provided by the National Environmental Satellite, Data, and Information Service of the National Oceanic and Atmospheric Administration (NOAA), shows that the water near the Florida Keys is significantly higher than usual, which causes coral bleaching and other marine life concerns.

The Gulf of Mexico is not the only place that is suffering this marine heat wave. 40% of the globe is experiencing extreme temperatures, Dillon Amaya, a physical scientist at NOAA, stated in an interview with the New York Times.  

The current water temperatures are the hottest ever recorded. Scientists say that these high temperatures are typical, but not until August or September. It is only July. 

The marine heat wave is mainly due to a climate phenomenon, El Niño, that typically brings warmer ocean temperatures. However, now El Niño is coming on top of long-term warming caused by greenhouse gas emissions and worldwide contribution to global warming.  

When sea temperatures rise too high, corals bleach, expelling the algae they need to live. If the water does not cool quickly enough, and if bleaching events happen frequently, the corals die. Coral reefs are vital to the marine life that relies on them and 25% of all marine life — including more than 4,000 kinds of fish — depends on reefs, according to NOAA. 

“Could a new PNT constellation using LEO satellites fully replace the services provided by the four existing GNSS constellations?”

---

“From a pure capabilities standpoint, the answer is “Yes”. LEO constellations can provide the PNT performance metrics that users require. However, should this strategy be followed, it would lack the diverse, complementary solutions needed to ensure the safety, security, and efficiency of critical infrastructure. Many have recognized the need for resilient PNT solutions and identified system-of-systems approaches. Multiple satellite constellations — MEOs and LEOs (despite the number of platforms) — lack this needed resilience. A resilient system-of-systems should include satellites in multiple orbits and complementary ground-based PNT infrastructure, each providing needed performance and overall demonstrating resilience from diverse threats.”

— Mitch Narins
Strategic Synergies

---

“In theory, yes. With a much stronger signal (antijam) that is encrypted (antijam), they counter GNSS’s two main vulnerabilities. However, with a paid service business model, it is difficult to compete with a free service. Moreover, large constellations are needed to overcome GDOP. OneWeb, Starlink, et al. already have launched and will continue to launch large constellations, so they must compete with these high bandwidth communications constellations that can provide accurate PNT as a side service and don’t have a GDOP limitation because of their size. Adoption of a single-purpose PNT system will be difficult.”

— John Fischer
Orolia

---

“Yes, it could. That said, as with any new product or technology, evolution of PNT capabilities will be dependent on competition, value or threats that undermine the current environment. Burgeoning systems such as Xona, Satelles or any number of augmentations utilizing “signal of interest” such as Starlink will rightly contribute to the evolution of enhanced PNT. Current advantages of LEO-based systems such as increased received power, decreased convergence time and numerical diversity are noteworthy, but replacing an investment of $100B+ government backed GNSS systems that adhere to well established policies and published ICDs is another.”

— Bernie Gruber
Northrop Grumman

---

“As my colleagues above note, the answer is yes from a technical perspective. However, in practice, not so much. Even with software-defined receivers, issues of signal reception and processing, interface standards, comm/nav service prioritization, security, integration into complex systems, integrity assurance, etc. make use of such nav services in lieu of purpose-built GNSS services impractical.”

Russia released a large number of attack UAVs targeting Kyiv, Ukraine, in the early morning of June 20, reported the New York Times. The UAV attack on Kyiv was the first in several weeks after Russian forces repeatedly targeted the city throughout May.

The air-raid alert started in Kyiv around 3 a.m. local time and lasted for more than three hours, as UAVs came in waves from all directions. According to the New York Times, Ukraine’s Air Force said Russian forces had launched 35 Iranian-made UAVs around Kyiv.

Ukraine air defenses shot down 32 of the UAVs, which included more than a dozen near the capital.

On June 21, Reuters reported that Russian air defense had downed three UAVs in the Moscow region in what they believe to have been a Ukrainian attack. The Defence Ministry stated that Russian forces had used electronic jamming, which caused the UAVs to lose control and crash.

Reuters could not independently verify details of this incident or who had launched the UAV attack.
