Agreement focuses on increasing development and capacity for ultra-compact, low-power laser-beam scanners to expand the market
STMicroelectronics and OQmented, a startup focused on MEMS-mirror technology, have agreed to collaborate on the advancement of the technology for augmented reality and 3D-sensing markets. Micro-electro-mechanical systems (MEMS) combine tiny 3D mechanical structures and electrical circuits on a chip to sense and actuate activity.
The joint effort aims to build on the expertise of both companies to advance the technology and products behind the leading MEMS-mirror-based laser-beam scanning solutions in the market.
ST manufactures MEMS sensors, actuators and related components including drivers, controllers and laser-diode drivers. ST is contributing its MEMS design and manufacturing resources to the collaboration.
OQmented plans to further industrialize and mass produce its Bubble MEMS technology, a patented 3D glass-encapsulation method of hermetic vacuum sealing of MEMS micro-mirrors. The glass bubbles eliminate environmental contaminants and minimize light-refraction effects.
Automotive grade. Vacuum sealing is a key element for meeting automotive-grade requirements, while simultaneously reducing power consumption by an order of magnitude and enhancing performance for resonant, bi-axial scanners, where the MEMS mirrors move in both axes at their resonant frequency, creating an ultra-compact and power-efficient scanning solution. The resonant mirrors are suitable for display and 3D sensing applications in mobile devices.
“In teaming with ST, we’ve chosen a solid semiconductor partner that has demonstrated its leading position in design and manufacturing of MEMS products, particularly MEMS mirrors, over the past 20 years,” said Ulrich Hofmann, CEO/CTO and co-founder, OQmented. “Combining ST’s expertise in developing, marketing, and manufacturing key components for laser-beam scanning solutions with OQmented’s knowledge and intellectual property will contribute greatly to our product offering, manufacturing capacity, and marketing channels, while also expanding the market in numerous application areas.”
“Our goal in working with OQmented is to leverage our shared expertise and deep understanding of laser-beam scanning technologies with the mutual vision to continue the adoption and growth of laser-beam scanning in key applications, such as augmented reality and 3D sensing,” said Anton Hofmeister, vice president and general manager, MEMS Microactuator Division, STMicroelectronics.
From the joint effort, ST and OQmented plan to market a wide range of scanning solutions. These would include MEMS mirrors, MEMS drivers and controllers, and complete reference designs of laser-beam scanning engines for a range of applications. The companies also intend to collaborate on a laser-beam scanning roadmap and the development of future technologies and products.
Oxford Technical Services (OxTS) has launched precision time protocol (PTP) master functionality on all of its next-generation inertial navigation systems (INS).
PTP is a network-based time synchronization protocol used to synchronize all clocks throughout a computer network. It is used in many industries, but most notably in finance to synchronize transactions, mobile-phone tower transmissions and subsea acoustic arrays.
Time synchronization
In many commercial organizations, millisecond-level device synchronization as offered with network time protocol (NTP) is sufficient. However, in surveying and automotive testing environments where there is more than one clock source (lidar and inertial navigation systems, or INS, for example), final results can suffer from time drift if millisecond — and not microsecond — synchronization is used.
Time drift becomes relevant as soon as you introduce more than one data acquisition system working in parallel. This is because each system will have its own timing error, and over time this error will grow and create drift.
For surveyors, time drift can negatively impact point clouds by making object recognition difficult, subsequently leading to blurring and double vision.
For automotive engineers, when running campaigns, analysis of events within your data may be misaligned, making the analysis more difficult and/or less efficient.
Stamp out time drift
To stamp out time drift, it is important to use the most accurate clock source available.
A key component of an INS is the GNSS receiver. The GNSS receiver acquires data, including timing information, directly from multiple GNSS constellations (GPS, GLONASS, BeiDou and Galileo). The GNSS receiver, coupled with the inertial measurement unit within the INS, allows users to benefit from the centimeter-level position accuracy that is so important in surveying and automotive testing environments.
These satellite systems house the most accurate time source possible — atomic clocks — meaning that devices connected to a network that includes an INS can take advantage of this time source owing to the GNSS receiver within the INS.
Simpler setup for lidar use
By migrating from a traditional PPS hardware set-up, which involves connecting and wiring multiple cables, to a PTP setup, which is essentially an Ethernet “plug-and-play” solution, users can also make day-to-day use of the equipment simpler and more efficient.
Without PTP – using PPS setup. (Image: OxTS)An example PPS hardware setup with a PTP-enabled network. (Image: OxTS)
This much-improved hardware setup allows surveyors and automotive test engineers to be up and running in a much shorter time frame than previously possible.
Adding value to the automotive industry
The addition of PTP also adds value for automotive users. With cars-under-test incorporating multiple sensors (lidars, cameras, etc.), synchronizing all that data can help support accurate analysis after the test is complete.
OxTS is continuing to develop its PTP solution by working on PTP slave functionality and improving the configuration process, which will provide greater flexibility in typical automotive setups that use data acquisition (DAQ) for larger sensor networks.
Summary
PTP as a time synchronization method is becoming more popular, particularly in the lidar industry, with manufacturers such as Ouster and Hesai enabling PTP on their sensors.
The shorter “time to survey” gives customers a much-enhanced user experience, and the higher quality final output on offer means that many users will demand their sensors are PTP-compatible before considering them for their projects.
Manufacturers of complimentary sensors, such as INS, need to build the capability into their product sets to allow them to be fit for the future.
Various OxTS INS are available to use PTP, including the new xNAV650, the company’s new small, lightweight and affordable INS for applications where payload size and weight matter. Learn more about the xNAV650 INS.
Users can also find out more about OxTS and its range of PTP-enabled devices by visiting its dedicated landing page, OxTS PTP-enabled INS devices.
Lidar and photogrammetry payload maker Rock Robotic has finished development of its new Rock R2A payload. Featuring the Livox Avia lidar scanner mounted on an aluminum enclosure, the R2A is light enough to fly on the DJI Matrice 200 and 210 series (versions 1 and 2), Matrice 300 RTK, Matrice 600 Pro, Freefly Alta X and many custom platforms.
A major factor in Rock Robotic’s success has been its use of Inertial Labs’ inertial navigation systems in its payloads. The Rock R2A uses the INS-D-OEM, which features temperature-calibrated and precisely aligned tri-axis micro-electromechanical accelerometers and gyroscopes.
With 20 years in the position, navigation and timing industry, Inertial Labs has been able to develop hardware solutions integrating many different types of sensors to ensure accurate time synchronization among independent data packets, resulting in a guaranteed high-performing system-level solution.
These high-quality systems and components, paired with a robust onboard Kalman filter, result in trajectories with heading accuracies of 0.03 degrees and pitch-and-roll accuracy of 0.006 degrees. These values directly affect point-cloud accuracy, which for the Rock R2A means a system accuracy of 5 centimeters or less.
The advent of drone lidar payloads has had a profound impact on industrial inspections such as for powerlines, saving labor costs and improving safety. The multiple return method of scanning with the Livox Avia and excellent position and orientation accuracy from the INS-D-OEM ensure that the R2A provides a highly dense and accurate point cloud for powerline classification.
“The Inertial Labs team has a deep understanding of the whole navigation technology ecosystem,” said Rock Robotics CEO and Co-Founder Harrison Knoll (known on YouTube as Indiana Drones). “This has made their products offer world-class performance and maintain easy integration and interoperability with GNSS receivers and onboard computer systems.”
New modules enable users to develop high-precision solutions for heavy machinery, ground robotics, and unmanned aerial vehicles (UAVs).
U-blox’s latest multi-band high-accuracy timing modules concurrently support L1 and L5 GNSS signals. The ZED-F9T-10B and LEA-F9T-10B timing modules, and the RCB-F9T-1 timing card, deliver nanosecond-level timing accuracies required to synchronize cellular network base stations and smart power grids. The ANN MB1 L1/L5 multi-band antenna completes the offering.
The multiband capability compensates for ionosphere error from all GNSS satellite constellations and reduces the timing error under clear skies to less than 5 ns without the need for an external GNSS correction service. To achieve maximum performance, the modules track signals from as many satellites as possible.
Image: u-blox
With satellite constellations transmitting signals on the L5 band nearing completion, the L1/L5 signal combination is becoming a viable option to complement products based on L1 and L2 signals. Modernized L5 signals are expected to deliver improved performance, especially in difficult urban conditions. Because L5 signals fall within the protected aeronautical radionavigation service (ARNS ) frequency band, they are also less subject to RF interference.
The LEA-F9T-10B provides a temperature range extended to –40 to +105° C. Both timing modules include a suite of advanced security features, including:
Improved anti-jamming and anti-spoofing technologies detect and flag malicious RF interference.
Secure boot ensures that the modules can only boot with authentic firmware.
Secure interfaces prevent intruders from tampering with the messages between the receiver and the host system.t
The ANN-MB1 L1/L5 multi-band antenna supports the GPS, GLONASS, Galileo and BeiDou, and addresses the scarcity of options in the nascent L1/L5 high-precision antenna mass-market, simplifying testing and deployment of L1/L5 multi-band GNSS solutions. Magnetic and fixed mounting options help meet diverse installation needs.
The new products targets developers in industrial navigation and robotics interested in high-precision positioning technology to locate UAVs, ground robots and agricultural equipment accurately and in real time.
Engineering samples of the u-blox ZED-F9T-10B, RCB-F9T-1 and ANN-MB1 will be available in May, followed by the LEA-F9T.

Among the enhancements, a doubling of the update rate means the GSS9000 series now offers the ability to recreate operations more precisely and realistically, reducing uncertainty in positioning, navigation and timing (PNT) testing.
The latest developments provide the GSS9000 series with the ability to run simulations at a software and hardware update rate of up to 2 kHz, improving accuracy of the simulated trajectory without compromising performance. This is of particular benefit to high-dynamics applications, such as space missions and hypersonic vehicles. The increased update rate also delivers lower latency for hardware-in-the-loop (HIL) testing, further reinforcing the GSS9000’s position as the industry’s most accurate and realistic test instrument.
“Our dedicated hardware and powerful software solutions are built specifically with PNT test in mind — to improve accuracy, increase flexibility and provide high-performing systems to meet customer needs,” said Adam Price, Spirent director of PNT simulation. “These latest enhancements to the GSS9000 continue to raise the bar for highly flexible and scalable solutions that enable our customers to stay ahead of their competition.”
Other enhancements to the GSS9000 Series include:
Extended Scenario Duration. In a simulation environment, where control and repeatability are key for a realistic representation of the mission, reducing the number of user inputs is essential. The new update will extend the available scenario duration to 65 days, using the same initial conditions for the simulation throughout the duration of testing to deliver uninterrupted high-performance simulation for longer.
Enhanced Embedded Interference Capabilities. To provide greater power and flexibility in interference testing, Spirent has improved support for interference testing on wide spectrum signals, increased bandwidth resolution and repetition rates, and added variable bandwidth control on additive white Gaussian noise (AWGN).

OSNMA (Open Service Navigation Message Authentication) offers end-to-end authentication on a civilian signal, protecting receivers from spoofing attacks.
OSNMA is being pioneered by the Galileo Program, with Septentrio providing a testbed for this technology from the end-user point of view. The anti-spoofing capabilities of OSNMA will complement Septentrio’s already available anti-jamming technology, AIM+, and further strengthen the overall security of Septentrio GNSS receivers.
“The authentication of the Galileo signal using the OSNMA technology is yet another first that we are pleased to share with our close partner ESA [European Space Agency],” commented Bruno Bougard, R&D director at Septentrio. “Septentrio is proud and thankful to be able to contribute to the realization of one of Galileo’s key differentiators. “
With OSNMA, Galileo is the first satellite system to introduce an anti-spoofing service directly on a civil GNSS signal.
OSNMA is a free service on the Galileo E1 frequency. It enables authentication of the navigation data on Galileo and even GPS satellites. Such navigation data carries information about satellite location — if altered, it will result in wrong receiver positioning computation.
While currently in development, OSNMA is planned to become publicly available in the near future. GPS is experimenting with satellite-based anti-spoofing for civil users with its Chimera authentication system.
Within the scope of the FANTASTIC project led by GSA, OSNMA anti-spoofing protection was implemented on a Septentrio receiver.
“Septentrio is committed to providing highly accurate and secure positioning and timing solutions to industrial applications and critical infrastructure. This is another example where Septentrio demonstrates its leadership in end-to-end GNSS receiver security with its breakthrough anti-jamming and anti-spoofing technology,” said François Freulon, head of Product Management at Septentrio. “Thanks to our future proof products, we will be rolling out OSNMA in our portfolio as soon as it is available. This will further enhance the security of our receivers, ensuring robust, trustworthy and reliable operation even in the most challenging environments.”

ESA and GSA (European GNSS Agency) have now commenced the testing phase of the OSNMA authentication, which will continue during the coming months. To find out more about spoofing and OSNMA, see this article. For more information about GNSS signals and the value they bring, see Septentrio’s free webinar More GNSS signals: What’s in it for you?

The 18-channel miniature full-constellation CLAW GPS Simulator is a fully self-contained, low size, weight, power and cost (SWaP-C) miniature GPS simulator. It is very popular in manufacturing environments as well as R&D applications that require consistent and repeatable local GNSS signals at low price points.
The CLAW simulator does not require external computers for processing and control — it works fully self-contained by simply applying power, and storing location/time/date data in internal non-volatile (NV) memory, or by storing complex vector data to simulate highly dynamic scenarios.
The CLAW also can be used to transcode NMEA or SCPI position/velocity/time (PVT) data into GPS RF signals. JLT offers an easy to use, highly configurable and cost-free SimCon Windows application program that is downloadable from the JLT website.
The SimCon application allows random scenario generation and is thus usable to simulate leap-second events, week 1023 rollover events, or any other GPS live-sky scenarios, including highly complex yet easy-to-create dynamic vector simulations.
For authorized U.S. government users, a version that does not have altitude and velocity limitations is popular for low-Earth-orbit (LEO) simulations. Multipath simulation allows use of the entire 18-channel simulator capability.
The unit can be field-upgraded with an easy to use in-field software upgrade feature. The CLAW is also very useful in GNSS receiver sensitivity testing for R&D or mass-production assembly lines as it allows accurate control of RF output power ranging from –100 dBm to less than –130 dBm with 0.1-dB resolution and typically better than 1-dB accuracy over the controllable power range.
The CLAW GPS Simulator also has a built-in RF signal generator with sweep, CW and random noise functions that are useful in simulating GNSS jamming scenarios, as well as GPS spoofing scenarios. The simulator comes in an FCC-certified metal desktop enclosure with numerous accessories.
For 2021, the CLAW firmware has been updated to allow live-sky almanac and ephemerides to be automatically uploaded from various externally connected GNSS receivers. This makes simulations using real-time live-sky constellations (such as used in simulating spoofing attacks) an easy task. A free firmware update is available from JLT.
The MGSE product family creates a versatile GNSS test and simulation environment that improves the development, qualification and certification process of GNSS receivers within development phases and for the validation and certification in end-to-end tests.
MGSE enables mobile and stationary interference monitoring, such as for protecting critical infrastructures (based on MGSE REC), and can be used for interference mitigation if combined with TeleOrbit’s GNSSA-6E (six-element antenna array) or its GNSSA-DCP (dual circularly polarized antenna).
With MGSE REC-REP 2.0 users can, among other tasks, record Galileo PRS signals in a real user environment and replay them for Galileo PRS receiver testing. It is also possible to replay simulated GNSS signals.
MGSE SIM-REP supports the development of software-defined radios/receivers (SDR) or specialized algorithms by creating a simulation environment that provides the possibility and flexibility to use synthetically generated GNSS data and recorded real-world samples — both exactly reproducible.
For jamming and spoofing test and evaluation, TeleOrbit offers a sophisticated solution based on the MGSE simulation, recording and replaying product family.
Technical background. The multi-band RF front-end (MGSE REC) receives the GNSS RF signals in different frequency bands simultaneously to obtain digital IF data, which can be used for GNSS multi-system signal analysis and comparison.
MGSE REC also includes a reception board to receive and process the NavIC S-band signal in addition to other L-band frequencies.
The MGSE Replay Unit (MGSE REP) includes a flexible multi-band RF replay device that can stream simulated and recorded raw IF data to a digital baseband output or to an analog RF signal.
MGSE REP simultaneously supports up to two independent RF channels and up to four GNSS signals, such as L1, E1, B1, G1.
Telit has launched the SE868SY-D multi-frequency, high-precision GNSS receiver module for applications that require high accuracy, fast updates, multi-constellation support and multipath resistance.
At 11 x 11 mm, the SE868SY-D accommodates ultra-compact devices and IoT trackers.
Available now, the high-precision SE868SY-D module is Telit’s first multi-frequency, multi-constellation GNSS receiver module, featuring an ultra-sensitive -167 dBm (tracking) RF front end. By using both the L1 and L5 bands, the SE868SY-D supplies a significantly higher location accuracy than single-frequency devices — even in high-multipath environments such as urban canyons, Telit said.
This sub-1-meter precision is a major reason ABI Research expects more than 1 billion multi-frequency GNSS devices to ship annually by 2023.
The SE868SY-D is the first product from a new strategic collaboration between Sony and Telit, and features Sony’s next-generation CXD5610 GNSS receiver large-scale integrated circuit (LSI).
The Telit SE868SY-D is designed for battery-powered applications such as IoT trackers and wearables. With less than 45 mW in L1+L5 tracking mode, the module has low power consumption, despite using both L1 and L5 bands.
For high-dynamic applications, the SE868SY-D a high update rate of up to 25 Hz. Its high-accuracy, one-pulse-per-second signal also makes the module suitable for timing applications.
“With the new SE868SY-D, Telit is uniquely prepared to meet the burgeoning global demand for multi-frequency, multi-constellation GNSS receivers for IoT trackers, wearables and more,” said Eric Lagorce, Telit business development director. “The SE868SY-D also perfectly complements Telit’s two decades of GNSS expertise and its broad portfolio, and highlights the potential of our strategic collaboration with Sony.”
The Telit SE868SY-D provides pin-to-pin compatibility for applications based on Telit’s legacy GPS module JF2 and GNSS module SE868V3.
The STL-2600 STL-capable receiver provides a GNSS-independent low SWaP-C UTC-time and location capability
Jackson Labs Technologies Inc. (JLT), a designer and manufacturer of GNSS, timing and frequency equipment, has announced the availability of the STL-2600 Satellite Timing and Location (STL) receiver designed in partnership with Satelles Inc., the STL service provider.
The STL-2600 commercial receiver provides a completely GNSS-independent, low-cost capability to generate UTC nanosecond timing and meters-accurate positioning anywhere in the world. It operates in a way similar to GPS, but without GPS or GNSS. The STL signal has 30-db (1,000 times) higher power compared to GPS signals, allowing the receiver to operate deep indoors independent of any GPS/GNSS signal.
“Useful for non-GNSS-based E911 location and UTC(NIST) timing applications, the STL-2600 receiver is deployable today to fulfill critical infrastructure PNT objectives such as those outlined in Executive Order 13905 on the responsible use of PNT in the U.S. and the emerging mandates for a GNSS-independent backup solution in Europe,” said Said Jackson, president of JLT.
The STL-2600 receiver is also useful in marine applications where GNSS signals are regularly denied or manipulated and for stationary high-accuracy timing applications such as 5G.
The STL-2600 receiver can be directly connected to JLT’s GPS Transcoder products for glue-less retrofit capability of existing customer legacy GPS-only receiver systems to Galileo, GLONASS, BeiDou, QZSS and SBAS as well as adding the STL and optional atomic holdover capability to these legacy systems.
The receiver module combines a custom-designed STL L1 LEO receiver and a latest-generation concurrent-GNSS receiver with a disciplined high-stability reference oscillator sub-system on one circuit board.
