InfiniDome has conducted testing and measurements in the Golan Heights along the Israel-Syria border. The goal of the tests was to hunt down jamming events, record them, see how they affect both protected and unprotected receivers, and then compare the results.
Two identical u-blox M8N receivers aboard a UAV were tested side by side, with one protected by GPSdome technology.
The GPSdome anti-jammer is a retrofit module that can be easily integrated to protect any GNSS-based system. It combines patterns from two omnidirectional antennas to create a null in the direction of the jamming signal, thus attenuating its power, making any GPS receiver about 50 times more resilient to jamming.
In a video of the tests, the GNSS receiver protected by GPSdome can be seen maintaining the GPS signal along the border, enabling uninterrupted navigation.
In contrast, the unprotected GNSS receiver loses the GPS signal during the attack, which can easily result in the drone becoming completely jammed, aggressively drifting and eventually crashing.
The Israel-Syria border experiences frequent jamming from Russian forces positioned in Syria, affecting critical border surveillance operations in the Golan Heights. Other global hotspots for jamming include the U.S.-Mexico border, where drug cartels use jammers on U.S. border surveillance drones, and the Shanghai port in China, where pirates may be the cause of ship and plane navigation confusion through use of jammers.
Jamming in Ukraine has also been well documented, with attacks from Russian forces taking down any plane, drone and even critical infrastructure asset in proximity, according to infiniDome.

The jamming attack was analyzed and appears not to have been a brute force attack, but rather a slightly more sophisticated signal, causing the receivers to “see” satellites but not be able to sync their signals and track them. The receiver protected by the GPSdome was able to distinguish between the real GNSS signals and the jamming signals.
In addition, GPSdome was able to attenuate the jamming signals sufficiently to be able to continue tracking the real GNSS signals while at the same time reporting the attack via its dedicated alert output.
Because GPSdome is both lightweight and easy to integrate (see integration diagram below), it can effectively provide much-needed resilience to drones and UAVs from widely available jammers, enabling drone operators to carry out missions safely and reliably.
Interview with Sara Masterson, Director, Positioning Services, Hexagon’s Autonomy & Positioning division, Hexagon | NovAtel
The accuracy of GNSS receivers continues to increase thanks to new satellites and signals, improved antennas, etc. How is that changing the role of correction services?
For sure, the accuracy of GNSS receivers and antennas is improving. However, most applications still require a higher level of accuracy than what is available from an uncorrected position even with the positioning improvements brought by new constellations and signals. GNSS corrections are still required to enable, say, lane-level accuracy, or sidewalk-block accuracy for autonomous driving or mobile phone applications and for off-road autonomy applications such as construction, mining, agriculture — these all still require centimeter-level accuracy that is enabled through GNSS correction services.
Corrections also help by improving the availability and reliability of a solution. In the future, corrections will play a key role in adding integrity to enable functionally safe solutions that are required for new applications, such as autonomous driving.
There are many options for corrections — local, regional and global, ground-based and satellite-based, public and private, etc. Which of them are generally best for which applications and conditions?
That depends very much on the user and the application. There are many new correction services in the market. Some are free, some are commercial services. Even now we see in agriculture that WAAS is sufficient for some broadacre-type applications. So, we will continue to see a range of applications, some of which will be satisfied with the level of performance from a free service and others that will be looking for the better performance and service level guarantees that come with commercial services.
If something is not working when you are using a free service, there’s no one to call. With commercial services, you get responsive customer support and you pay for higher levels of performance and service availability. In many applications, especially those that involve autonomy or safety applications, you cannot afford to have downtime, or your machine just stops working, which costs money. So, many applications are still going to be needing the performance and service level guarantee that commercial services offer.
How does TerraStar fit into this range of options? What industries and applications are you targeting?
TerraStar has a range of services that enable us to target many industries and applications. Agriculture, of course, is one of the key applications for our services and we have customers using TerraStar for mobile mapping, UAVs and new autonomy-based applications. We are also involved with some interesting Hexagon joint projects that use TerraStar corrections for mine train automation and surveying and construction.
Our entry-level TerraStar-L service is still better in performance to many of the free services or to an SBAS-type service in terms of accuracy, but it is available globally, including regions where you don’t have other options. It also provides better pass-to-pass and year-over-year repeatability, as well as very quick reconvergence time if there are any issues with GNSS outages.
Our flagship offering is the TerraStar-C PRO service. That’s where we just introduced the “RTK from The Sky” technology, bringing the performance down to converging to two and a half centimeters in three minutes. That, too, is available globally which makes it a real game changer for customers in many different applications, because they can start to look at that service as an alternative to RTK and without the added connectivity logistics that an RTK solution brings.
Our RTK assist solutions are good augmentation solutions for customers who still primarily need RTK but experience some RTK correction outages – RTK ASSIST bridges through those outages. So, we have a wide range of service offerings in the portfolio that can address the positioning needs of many applications.

Will the reasons for having a base and rover setup decrease sharply?
Use of base and rover setups is already decreasing and being replaced by both PPP and network RTK solutions. There are applications where RTK still makes sense, such as those that have very tight vertical requirements and many survey applications. Another Hexagon division, Hexagon’s Geosystems division, incorporates TerraStar correction data into their new SmartNet Global offering as a seamless service that provides both SmartNet RTK plus TerraStar for either bridging outages or independent PPP operation, depending on the project’s location and whether they’re within range of SmartNet coverage.
There will be many applications that continue to benefit from a combination of the two technologies. However, as the PPP services, like TerraStar, continue to improve by reducing convergence time and providing highly reliable solutions, users in those applications can be confident that the standalone PPP solutions meet their performance needs and bring many additional benefits such as consistent, global coverage and performance.
Is TerraStar completely receiver agnostic?
TerraStar is currently only compatible with NovAtel’s GNSS hardware. Going forward, through the work that I referenced with autonomous driving and mass-market applications, we will be providing TerraStar services in industry-standard formats, depending on the inter-operability requirements coming from those applications. We expect that there will be demand for dual sourcing of corrections and interoperability between chipsets that are used in vehicles, for example. For those applications, we will be developing TerraStar services that are compatible with hardware from other GNSS manufacturers.
Flyability has unveiled the Elios 3, a collision-tolerant drone equipped with a lidar sensor for indoor 3D mapping. The drone is powered by a new SLAM engine called FlyAware that lets it create 3D models as it flies.
It also is accompanied by a new version of Flyability’s software for inspectors, Inspector 4.0.
The launch of the Elios 3 marks a new partnership with GeoSLAM. The Elios 3 comes with an Ouster OS0-32 lidar sensor, allowing inspectors to collect data for the creation of survey-grade 3D models using software from GeoSLAM.
The drone gives users real-time digital replicas of previously inaccessible areas with the inclusion of the lidar sensor and GeoSLAM’s Connect software. The drone is protected by a cage and has advanced collision-tolerance features that allow inspectors to fly it inside dangerous confined spaces such as boilers, pressure vessels and mines.
With its integration with Connect, the Elios 3 creates survey-grade point clouds. Fitted to the back of the drone, the lidar sensor maps the environment in real time using Flyability’s FlyAware SLAM algorithm.
Survey package option
Those that need highly accurate data can upgrade to the survey package, provided by GeoSLAM, providing access to the Connect software, as well as specialist Volumes and Draw modules. Powered by GeoSLAM’s established SLAM algorithm, Connect offers a simple and automated way to process point cloud data.
Using the survey package, data is processed to an accuracy of 8 mm, suitable for mapping hazardous environments such as mines and industrial applications including chimneys, production plants, warehouses, silos and tanks. Processed data can then be viewed in the easy-to-use 3D viewer and exported to industry-standard file types including LAZ, LAS, PLY and TXT for use in third-party software.
YellowScan has released a new long-range lidar scanner. Voyager is a powerful solution for both manned and unmanned aircraft.
With Voyager’s wide field of view, all of the points collected are oriented toward the ground, meaning there is no loss of points. This also means 1.5 million points per second will be usable, which would not be the case with a 360° scanner.
Voyager combines a Riegl VUX-120 laser scanner with a Trimble Applanix AP+ 50 AIR or Applanix AP+ 30 AIR GNSS-inertial board, providing precision of 0.5 cm and accuracy of 1 cm.
Voyager’s detection and processing of up to 15 target echoes per laser pulse allows for excellent vegetation penetration. Its has an extremely fast data-acquisition rate of up to 1800 kHz, suitable for projects requiring the highest point density.
The laser scanner’s specifications can be customized to fit the needs of various projects and platforms, and can be combined with YellowScan’s full suite of software solutions to easily extract, process, merge and colorize point-cloud data.
Septentrio’s latest GNSS boards and modules now support PX4 Autopilot for faster integration of high-accuracy positioning into UAVs and robots.
Both the AsteRx-m3 and mosaic receivers support PX4 Autopilot, opening the door to reliable and resilient real-time kinematic positioning.
PX4 Autopilot is one of the largest commercially adopted open-source navigation control stacks, enabling an innovative community to build and maintain drone hardware and software in a scalable way. Drones and robots, which operate autonomously or where a high level of safety is required, now benefit from Septentrio’s accurate positioning receivers, known to be secure against GPS jamming and spoofing with built-in AIM+ Advanced Interference Mitigation technology.
“Our developer community is looking forward to integrating Septentrio’s secure GNSS positioning technology into UAVs and robots, especially in those applications where reliability matters from mapping to surveillance and delivery,” said Ramon Roche, general manager, Dronecode Foundation. “Septentrio’s presence and talk at the PX4 Developer Summit will be an opportunity for developers and integrators to connect with Septentrio and to learn about the latest high-accuracy positioning tech for the PX4 ecosystem.”
“Septentrio has had a fantastic collaboration momentum with Dronecode and the larger PX4 community during the integration of Septentrio receivers into the PX4 Autopilot ecosystem,” said Gustavo Lopez, market access manager at Septentrio. “This collaboration is important because it brings resilient and secure GPS technology to the UAV industry, with tremendous potential in terms of assured positioning and improved safety.”
PX4 is supported by Septentrio’s GNSS boards and modules with both single-antenna and dual-antenna configurations, which offer either heading and pitch or heading and roll angles on top of accurate GNSS positioning.
The Septentrio PX4 driver is freely available on the GitHub.
DeltaQuad has successfully integrated an advanced GPS anti-jamming system into its unmanned aerial vehicle (UAV). The DeltaQuad drone equipped with the system was flown in autonomous mode close to an active military jamming system.
Even while being hit directly by a military-grade GPS jamming platform, the system maintained a solid GPS lock and the vehicle managed to autonomously resume its mission without interruption.
For testing purposes, a ruggedized GPS-based navigation system was installed with the standard GPS-based navigation system. As the vehicle came in range of the GPS jamming system, the standard solution quickly lost all positional awareness, while the ruggedized system maintained a number of satellite locks, even while flying directly over the jammer at close range.

In addition to the ruggedized GPS solution, the DeltaQuad UAV is equipped to maintain live aerial intelligence, even in tough environments. The transmission system on the DeltaQuad uses frequency hopping spread spectrum (FHSS) techniques to mitigate attempts to disrupt the communication links, and also uses redundant video and communication links.
The DeltaQuad is an industrial-grade vertical takeoff and landing (VTOL) fixed-wing UAV that performs fully autonomous surveillance missions. The platform offers a live video stream from a surveillance sensor for real-time reconnaissance missions.

Plus: UAVs in Ukraine, vineyard protection and a royally awesome light show
Taser-equipped drones
We hear of mass shootings in schools, and this week on a crowded street in Philadelphia a school adviser was among those killed. Everyone continues to be outraged, but as we wait for any sort of positive, preventive action by our leaders, an idea from a drone developer was shut down before it even got out of the company.
Axon taser drone concept. (Photo: Axon)
Axon Air supplies Tasers and body cameras to police forces, and last year someone came up with the idea of loading a drone with a Taser so that it could find and suppress a gunman in a school. There are a lot of problems with the idea, and Axon’s own internal artificial-intelligence board nixed the idea.
Doors were the board’s primary concern. What happens if something triggers a drone to Taser kids in the classroom or hallway? Could autonomous drones or even multiple intelligent cameras detect an actual weapon of any description, and set off an automated response?
We use metal detectors on entry to some schools to deter carrying weapons to class, but how about recognizing carried weapons in the school? To even attempt an automated drone response, you would need multiple Taser-equipped drones in all areas of a school, as well as time to test and verify that any autonomous response would work correctly.
Could anything along these lines be something we might consider in any way?
Keeping watch at vineyards
A team at Washington State University (WSU) has come up with a new twist on an old idea. Hawks have been trained effectively in the past to chase off flocks of birds on or around runways at airports or to protect crops. Now WSU has developed a system that uses intelligent cameras to detect birds, and which is then able to dispatch drones to the invaded area to chase off the birds.
The system has been tested to protect local grapevines. Bird fruit losses were actually reduced by ~50% following manual drone flights, which also reduced the number of bird invaders four-fold.

Nevertheless, birds can learn over time how to get round such deterrence, so WSU proposes disguising drones as predator birds and arming them with distress calls or raptor-attack behavior. WSU is looking for wine-industry support to develop this approach into a feasible, deployable solution.
Grey Eagles might fly in Ukraine
The United States is considering providing Grey Eagle UAVs (the Army version of the Predator) to Ukraine — the first time a relatively high-tech drone with weapon-carrying capability would be supplied for the Ukrainian conflict.
The Grey Eagle can carry up to eight hellfire missiles, fly for 30 hours at relatively high altitude, and gather masses of surveillance information — a formidable, front-line weapon/reconnaissance system. Four UAVs are envisaged; missiles would not be included in the first round, but would likely come soon after.

Th Grey Eagle UAV system usually requires months of advanced training, but the Ukrainian forces have already been operating the smaller missile-carrying Turkish Bayraktar-TB2, so training may be reduced to a few weeks for operational necessity. Meanwhile, the sale must first be approved by Congress, so nothing is yet certain.

Before the war with Russia, Ukraine purchased up to 30 TB2 drone systems, and many have seen action in the current conflict. A crowdfunding effort by a TV station in Lithuania gathered enough cash to buy yet another TB2 to help Ukrainian forces stay in the fight.
However, Baykar, the Turkish manufacturer, declined the sale, instead offering to donate a TB-2 so that the Lithuanian funding could go toward humanitarian aid for the Ukrainian people.
Meanwhile, in Estonia the Internal Security Service (KAPO) arrested a man leaving the country who is suspected of supplying commercial drones to the Russian forces.

Honoring the Queen
Finally — on a much lighter, respectful note — a drone light show was a big hit over Buckingham Palace in London on the occasion of the Platinum Jubilee concert for Queen Elizabeth II.
The queen has been on the United Kingdom’s throne for 70 years. To celebrate, the Brits hosted a major shindig. As part of a concert held outside Buckingham Palace, 400 lightshow drones from SkyMagic flew above the palace. The drones created various designs, showing the message “Thank you, ma’am”, a Corgi, a handbag, a teapot pouring into a teacup, guards in busbies, and a figurehead postage stamp — all good fun received in good spirit by a huge milling crowd.
Food for thought
To sum up, maybe it’s not such a good idea to have drones equipped with Tasers in schools, but perhaps it’s an idea we could build on to better protect our kids.
Trained, autonomous drones that take off and chase birds when they descend on vineyards — could this be a better solution than low-slung netting?
The war in Ukraine rages on. Not only the West, but also some Eastern countries pitch in with support.
Finally we saw a drone light show for the queen during the Jubilee celebration of her 70 years reign. We’re seeing a lot of smart drone potential out there.
Amazon customers in Lockeford, California, will be among the first to receive Prime Air drone deliveries in the United States, later this year. According to an Amazon blog, the company has been working for almost a decade to make it a reality.
Customers in Lockeford will see Prime Air-eligible items on Amazon. They will place an order as usual and receive an estimated arrival time with a status tracker for their order. For these deliveries, the drone will fly to the designated delivery location, descend to the customer’s backyard, and hover at a safe height. It will then safely release the package and rise back up to altitude.
Customer feedback about Prime Air, with drones delivering packages in their backyards, will help Amazon create a service that will safely scale to meet the needs of customers everywhere, according to the company.
“Lockeford residents will soon have access to one of the world’s leading delivery innovations,” said California State Assemblyman Heath Flora, whose district includes Lockeford. “It’s exciting that Amazon will be listening to the feedback of the San Joaquin County community to inform the future development of this technology.”
“We are working with the Federal Aviation Administration (FAA) and local officials in Lockeford to obtain permission to conduct these deliveries and will continue with that collaboration into the future,” the blog said.
Amazon designed its drones’ sense-and-avoid system for two main scenarios: to be safe when in transit, and to be safe when approaching the ground. Its algorithms use a diverse suite of technologies for object detection, enabling it to identify a static object in its path, such as a chimney. It can also detect moving objects on the horizon, such as other aircraft, even when it’s hard for people to see them.
When obstacles are identified, the Amazon Prime drone will automatically change course to safely avoid them. As the drone descends to deliver a package into a customer’s backyard, it ensures that there’s a small area around the delivery location that is clear of people, animals or other obstacles.
Prime Air is one of three drone-delivery companies that has gone through the rigorous process to earn an FAA air carrier certificate, which will be required to operate drones using these advanced capabilities.
The Drone Tournament has relaunched following the COVID pandemic, and will take place June 8-10 in Helsinki, Finland.
In the competition, drones will compete to prove precision-control drones over land and sea. GNSS companies Septentrio, Spirent and u-blox will take part.
Sponsored by Ultrahack, the competition seeks to boost use of drone technology, including for 5G networks and satellites. The challenges are especially related to landing and precision flight in demanding and changing environments. Contestant drones will use a wide spectrum of navigation and sensor technology, including GNSS.
U-blox, Spirent and Septentrio are offering their GNSS technology for the participants.
Septentrio and u-blox will provide GNSS services that teams can use to increase performance as they land their drones on a moving boat. To help improve performance, Septentrio and u-blox will provide access to data streams from a base station on the shore and on the boat.
The streams will provide raw observations in RTCM3 format via NTRIP (which can be used to compute a real-time kinematic, or RTK, position of the drone). The stream from the boat will also provide position, heading and speed of the boat over an IP connection in NMEA or binary format.
Using these streams can help to obtain an RTK solution on the drone or to know the relative position between the drone and the boat.
The winners will receive monetary prizes and the possibility of negotiating commercial agreements for further development of their solutions.

The receivers include the capability to enable system integrators to choose either the L2 orL5 frequency to optimize signal performance and maximize the number of measurements available to the GNSS engine.
“The BD9250 provides centimeter-level RTX accuracy without the need of a base station,” said Finlay Wood, general manager, off-road, Trimble Autonomy. “This OEM GNSS board is ideal for high-volume autonomy applications that require precise positioning, without sacrificing accuracy, availability or integrity — enabling integrators to bring systems to market faster.”
The Trimble BD9250 and BD9250s evaluation receiver modules and the Trimble RTX correction service subscription are available now through Trimble’s OEM GNSS sales channel.
WingXpand has debuted a 7-foot expandable-wing drone that fits in a backpack. The drone was first revealed to the special forces community at the Special Operations Forces Industry Conference (SOFIC 2022) held May 16-19 in Tampa, Florida.
WingXpand is U.S. made with a patented design that takes the small size and simplicity of a quadcopter and combines it with the horsepower of an airplane. WingXpand maximizes capability, efficiency and safety for the military and public safety officials. It can also be used by farmers, surveyors and inspectors.
WingXpand expands in less than 2 minutes. Though the full system weighs less than 10 pounds, it flies five times longer and carries ten times more weight than other drones of its size class, according to WingXpand. It can carry high-resolution cameras and other modular payloads such as a real-time pattern analysis system.
WingXpand can reduce or replace the need for more costly, scarce or dangerous options. More than 10 WingXpand UAS can fit in a public safety vehicle, more than 30 in a pickup, and 250 on a standard airlift pallet.
The WingXpand team provides end-to-end services, including pilot services, training, data analysis and sustainment.
