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.

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.

IEEE 1588 precise timing grandmaster with gateway clock now offers software-based redundancy
Photo: Microchip
For today’s critical infrastructure providers — 5G wireless networks, smart grids, data centers, cable and transportation services — a fundamental need exists for a redundant, resilient and secure precise timing and synchronization solution.
Microchip Technology Inc.’s TimeProvider 4100 Release 2.2 grandmaster provides a new level of resiliency with the introduction of an innovative redundancy architecture in addition to support for a multi-band GNSS receiver and enhanced security to ensure always-on precise timing and synchronization.
Redundancy is key for infrastructure providers to ensure uninterrupted services. Infrastructure deployments previously relied on hardware redundancy to avoid service disruption despite costly modular architectures. Microchip’s TimeProvider 4100 Release 2.2 grandmaster provides redundancy via software implementation, enabling flexible deployment and lower hardware costs without sacrificing ports.
In addition, the TimeProvider 4100 Release 2.2 grandmaster introduces an increased level of resiliency by supporting a new GNSS multi-band, multi-constellation receiver to protect against time delay resulting from space weather, solar events and other disruptions that may impact critical infrastructure services.
Multi-band GNSS is particularly important for the highest levels of accuracy, including primary reference time clock class B (PRTC-B, 40 ns) and enhanced primary reference time clock (ePRTC, 30 ns).
With a focus on security solutions across its technology portfolio, Microchip’s new TimeProvider 4100 Release 2.2 grandmaster adds support for RADIUS and TACACS+ as well as new anti-jamming and anti-spoofing capabilities.
“Resilient, redundant and secure precise timing and synchronization solutions are necessary to mitigate security risks to critical infrastructure,” said Randy Brudzinski, vice president and general manager of Microchip’s frequency and time business unit. “This latest release brings an innovative software redundancy that enables always-on technology as well as support for multi-band GNSS to eliminate ionospheric time error delays. It provides new key security, anti-jamming and anti-spoofing so critical infrastructure services can be accessed only by authorized, authenticated personnel.”
In addition, the TimeProvider 4100 Release 2.2 grandmaster provides a super oven controlled crystal oscillator (OCXO) option for enhanced holdover capabilities in case of GNSS disruption.
The TimeProvider 4100 Release 2.2 grandmaster is a family of products with hardware expansion modules for legacy fan-out or Ethernet fan-out with 10 Gigabit Ethernet support. It can be configured in specific operation modes to act either as a gateway clock, a high-performance boundary clock or an ePRTC.

It’s hard to pick out an outstanding story or two this month from the dozens of new or related drone initiatives that bombard my inbox. But there’s always some that stand out, needing emphasis. This month, we look at these developments:
NEC Laboratories Europe introduces a potential drone solution for finding disaster victims
The FAA issues its remote ID rule, which also enables flight over people and nighttime operations
The Boeing Loyal Wingman succeeds with its maiden flight in Australia.
Search-and-rescue drone
Finding survivors is a primary task for first responders in disaster situations, so if a feasible approach using drones looks possible, its something we should prove out and implement quickly. Researchers at NEC Laboratories Europe, based in Germany, have come up with a drone shown to be able to locate a person’s cell phone — it works better in open situations, but takes longer and is less accurate when there are obstructions.
The Search-and-Rescue Drone (SARDO). (Photo: NEC Labs/Antonio Albany)
The concept of the search-and-rescue drone (SARDO) is basically to hang cellphone-tower electronics on the drone, and then let it self-triangulate on the return signal from the victim’s phone. So if you know where you are and estimate distance by pinging the victim’s phone and measuring the transit time, then move a known distance and repeat, eventually you converge on the phone’s location.
Putting all that into reliable flying algorithms is something; proving that your design works is significantly more tricky. Overcoming signal blockage due to debris brings another level of complexity, as does tracking the victim if he or she is moving.
But this looks like a great initiative which should be developed further — a possible boon for finding people in earthquakes and other building-collapse situations.
FAA Remote ID Rule issued
Image: ConceptCafe/iStock/Getty Images Plus
On Jan. 15, the U.S. Federal Aviation Administration (FAA) finally issued its rules for remote ID: All UAVs greater than 0.55 pounds must transmit unique identifications. Although, it appears that even these lighter drones might also have to be capable of remote ID if operated commercially. The broadcast message has to include “identification, location, and performance information of the unmanned aircraft and its control station.”
The good news is that there are now several potential suppliers of these broadcast modules. The rules allow for an implementation period that stretches out another 18 or 30 months — UAV manufacturers have 18 months to comply, while drone operators have 30 months.
The rules also allow drone operators to fly their UAVs over people. There are four categories of drone, each with appropriate restrictions — all seemingly related to the injuries an out-of-control or falling drone could cause to a person. All such operations require that the FAA approve a written statement of compliance with these safety rules.
The rules will certainly help with coverage of spectator sports such as the Super Bowl and regular outdoor events like PGA golf tournaments. It would appear that the Golf Channel and CBS have already begun to broadcast drone coverage of recent golf events. Such operations needing to verify their compliance now, rather than over the implementation period.
And, of course, if you can fly over people, transiting over vehicles is now allowed. With an anti-collision light installed, night operations are also permitted once compliance is approved.
The UAV/UAS is also referred to as the Airpower Teaming System (ATS), and should likely be considered a contender for the U.S. Air Force Skyborg manned-unmanned teaming program. At least two other companies involved with the Skyborg program are already flying similar vehicles — Kratos Unmanned Aerial Systems and General Atomics Aeronautical Systems.
Summary
Anything that helps first responders find survivors in disasters is a good idea to take to users in the field as soon as possible, so the NEC Laboratories Europe initiatives is a welcome opportunity.
After more than two years to get the final rules published, the FAA is finally coming online with its Remote ID rule — even though it entails significant work on operators’ parts over the next several months for them to implement. But the window now seems to be significantly wider for them to be able to take on more viable commercial business ventures.
Finally, it’s good to see the Boeing ATS get into the air — the first aircraft in 50 years to be wholly built in Australia, with interest not only from the Australian RAAF, but also with potential participation in the USAF Skyborg program.
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).
“Spirent’s leadership in GNSS testing comes from the combination of our unrivalled heritage and deep understanding of the PNT market, alongside our continuing commitment to improving test capabilities for customers,” said Ricardo Verdeguer Moreno, product line manager for high-end applications. “By working closely with customers, we are able to better understand the challenges they face, and these latest enhancements to the GSS9000 series demonstrate how we are continuing to help customers reduce uncertainty by providing more accurate operations, without impacting system performance.”
The enhancements to the Spirent GSS9000 series will be available to new and existing customers at the beginning of the second quarter of this year. For more information, visit the GSS9000 Series product page. U.S. government and prime contractors should contact Spirent Federal for details.

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.
Zala Aero Group unveiled the ZX1, a new hybrid unmanned aerial vehicle (UAV), at the 2021 International Defense Industry Exhibition (IDEX) and Conference, which opened on Feb. 21 in Abu Dhabi.
The new drone has vertical-takeoff-and-landing (VTOL). According to Zala, it combines the best qualities of fixed-wing and multirotor types of UAVs; its configuration can change depending on the conditions of the performed task.
Ease of operation allows the UAV system to reduce the operator’s role, decrease the amount of equipment used when performing a flight mission, and fully automate flight processes of the UAV.
The ZX1’s onboard computer uses artificial intelligence, which makes it possible to process data in full high-definition, and transmit HD video and photos via encrypted communication channels to the GCS, ensuring the effectiveness of monitoring even before the aircraft lands.
The VTOL design makes it compatible with existing ZALA payloads, and also allows the installation of additional surveying equipment. It can be used to perform air monitoring for the fuel and energy sector and search-and-rescue operations from sites in urban environments.
Zala Aero Group, founded in 2004, is a Russian developer and manufacturer of unmanned aerial systems, payloads and mobile systems. It is now part of Concern Kalashnikov. Its main products are reconnaissance unmanned systems and digital solutions. Currently, more than 2,000 of Zala UAS operate within Russia. Areas of application are the protection of state borders, reconnaissance and rescue operations, monitoring of high-risk facilities and emergencies.
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.

L3Harris Technologies has received contracts totaling $137 million for four navigation payload Mission Data Units (MDU) for future GPS III Follow-On (GPS IIIF) satellites.
Lockheed Martin, the prime contractor for GPS III/IIIF, selected L3Harris in 2018 to design and build the first two fully-digital MDUs, the heart of the satellite’s navigation payload. The MDU generates more powerful GPS signals and assures clock operations for GPS users, L3Harris said.
“The digital MDU is flexible enough to adapt to advances in GPS technology and future changes in mission needs,” said Ed Zoiss, president, Space and Airborne Systems, L3Harris. “The new MDU will also support a smooth transition for the U.S. Space Force’s GPS OCX ground control segment.”
The U.S. Space Force expects the first GPS IIIF satellite, which builds on GPS III adding new capabilities and technology, to be available for launch in 2026. According to L3Harris, the GPS IIIF MDU will provide improved capabilities over L3Harris’ 70-percent-digital MDU on the first ten GPS III satellites. The first four GPS III satellites have successfully launched and are now operational in the GPS constellation.

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.
