Tallysman Wireless has added new eXtended Filtering (XF) features to the TW3900 series of Accuntena precision antennas. Tallysman designed the XF feature to mitigate interference from all near-band signals and ensure that the antenna provides the purest GNSS signals.
Tallysman’s TW3972XF, TW3972EXF, TW3972LGXF, TW3967XF, and TW3967LGXF are triple-band antennas that support GPS/QZSS (L1/L2/L5), GLONASS (G1/G2/G3), Galileo (E1/E5ab), BeiDou (B1/B2/B2a), NavIC L5, and L-Band correction services.
Worldwide, the radio frequency spectrum has become congested as many new LTE bands have been activated, and their signals or harmonic frequencies can affect GNSS antennas and receivers. In North America, the planned Ligado service, which will broadcast in the frequency range of 1526 to 1536 MHz, can affect GNSS antennas that receive space-based L-band correction service signals (1539–1559 MHz).

New LTE signals in Europe [Band 32 (1452–1496 MHz)] and Japan [Bands 11 and 21 (1476–1511 MHz)] have also affected GNSS signals. Lastly, the Inmarsat satellite communication uplink (1626.5–1660.5 MHz) commonly used on maritime vessels can also affect nearby GNSS antennas.
Tallysman’s custom XF filtering has been tested to mitigate new (Europe and Japan) and existing LTE signals, enabling the XF antennas to produce clean and pure GNSS radio frequency data. The deep XF filter technology will be applied to all of Tallysman’s product lines.
Rx Networks has added a new extended ephemeris service called StarCourse.
According to the company, real-time ephemeris services provide GNSS chipsets in connected mobile devices a headstart in determining position accurately and quickly. For devices with limited connectivity, typical extended ephemeris solutions have provided a headstart with 7-14 days of ephemeris data.
With the evolution of the internet of things (IoT), low power consumption and a limiting of connection time are essential for extending the usable life of a device. This creates a challenge for IoT vendors seeking an extended ephemeris offering that can minimize onboard resource usage without compromising accuracy.
The new StarCourse service provides a 50% reduction in RAM requirements, 90% reduction in CPU cycles, and ephemeris accuracy exceeding that of previous market offerings. This empowers Rx Networks customers to extend the usable life of their products while delivering an excellent positioning experience, the company said. Full data customization is offered to StarCourse subscribers, allowing them to create optimal solutions for their needs.
StarCourse enables autonomous positioning on a wide array of connected GNSS IoT devices, including asset tracking, wearables, in-dash navigation and mobile devices. For situations where accuracy is paramount, StarCourse Premium provides ultra-precise predicted ephemeris for the first 24 hours.
“GNSS assistance services are essential to solving the spatial intelligence requirements of the booming IoT world,” said Chris Perriam, product owner at Rx Networks. “StarCourse endeavours to quickly enlighten all connected devices with location.”
Rx Networks provides location information to strengthen the connection between people, devices and businesses by improving the GNSS experience and creating enhanced opportunities for next-generation products and services.
Hexagon AB has acquired Immersal Oy, an innovator of spatial mapping and visual positioning solutions for producing augmented reality (AR) applications.
AR applications enhance real-world experiences by augmenting a user’s visual perception with the display of digital content in the physical world.
AR’s ability to weave context-specific, 3D information into physical spaces provides endless opportunities to save time, improve performance and reduce costs across a wide range of industries and applications — from surveying, construction, public safety and manufacturing to maintenance, training and navigation applications.
An immersive experience can help boost task efficiency, improve safety protocols, optimize workflows and increase collaboration.
The Immersal SDK (software development kit) allows developers to merge and “anchor” digital content to real-world objects – with precise accuracy to their actual location in the physical space — by enabling a user’s mobile device to locate and orient itself in the surrounding physical world using machine-readable maps.
The maps, which are used for visual positioning, are constructed from image data supported by various mapping devices (including mobile phones) and hosted in the Immersal Cloud Service.
“Hexagon has long been a leader in delivering smart digital realities that combine inputs from reality capture sensors with advanced visualisation software and tools to enable remote, location-based intelligence. This acquisition puts the power of these insights into the hands of those on-site, enhancing their field of view with superimposed digital information, meaning they can literally do more with what they see,” said Hexagon President and CEO Ola Rollén. “For example, direct access to information about an asset — while working with that asset — including step-by-step instructions on how to repair it, can streamline maintenance tasks while reducing material waste and re-work.”
Immersal has years of experience developing AI and machine learning-based spatial anchor technology, which “anchors” virtual objects or models for viewing on different devices in the same position and orientation. This unlocks a wide variety of location-based solutions and services — from consumer-oriented augmented reality applications in gaming and media and entertainment to digital twin solutions on an enterprise scale.
Immersal’s technology can map large spaces — both indoors and outdoors — and works both offline on-device and online using the Cloud Service.
Founded in 2015 and headquartered in Helsinki, Finland, Immersal will operate as part of Hexagon’s Geosystems division. The acquisition has no significant impact on Hexagon’s earnings.
Deal makes data from 40 Chinese satellites available through UP42 now, another 40 by late 2021
UP42 has signed an agreement with HEAD Aerospace of Beijing to make image data from more than 40 Chinese Earth Observation satellites available on the UP42 marketplace.
The broad selection of imaging capabilities from the constellations dramatically expands the range of applications in multiple sectors, with the most significant benefits expected in infrastructure, transportation, utilities, agriculture and government.
The UP42 marketplace contains more than 50 geospatial data sets, including satellite imagery from six international organizations. The newly added satellites’ diverse and often unique imaging capabilities include wide-swath imaging at very high resolution, nighttime acquisitions, frequent intraday revisits, tri-stereo collection and hyperspectral imaging.
“This partnership is an important milestone for us as a company but, more importantly, for our customers. By diversifying our data sets, we are unlocking a broader spectrum of use cases for our users in multiple sectors. This is the true meaning of ‘democratizing access to Earth insights’,” said UP42 CEO Sean Wiid.
HEAD Aerospace is an international distributor of satellite imagery collected by commercial Earth Observation missions. The UP42-HEAD agreement includes imagery from multiple constellations, including SuperView, Earthscanner, Gaofen-7, DailyVision, NightVision, Hyperscan, and Tri-Stereo ZY3. These seven constellations will total more than 80 satellites by the end of 2021.
“Sharing a similar approach facilitating users’ easy access to an agnostic data source by a centralized portal with a wide choice of satellite attributes, we are glad to have partnered with UP42. This partnership represents another new milestone for us in expanding our global network.” said Kammy Brun, managing director of HEAD Aerospace.
While each satellite constellation was designed with one or more imaging specialties, a remarkable variety of operational capabilities are shared across the constellations to support numerous applications and industries. Examples include:
Large-Area Very High-Resolution Mapping – Planning and monitoring critical infrastructure, including utility transmission grids and transportation networks, can be performed for entire states, countries and regions. Up to 40,000 square kilometers can be covered with wide-swath (136 km) imagery captured at a half-meter spatial resolution on a single pass.
Intraday and Early Morning Monitoring – The EarlyEye tasking product leverages multiple HEAD Aerospace constellations to deliver early-morning frequent images, an hour earlier than usual commercial offer at 10:30 a.m. Designed for frequent monitoring of critical assets and rapidly changing situations related to energy security, defense/intelligence and infrastructure management, a high-resolution revisit schedule of four times per day is possible, with 15-minute revisit between 09:00 and 13:30 anywhere on Earth to be possible by the end of 2021.
High Vertical Accuracy Mapping – Multiple satellites perform stereo imaging at high resolution for high-quality land use and cadastral mapping. One constellation captures single-pass tri-stereo imagery validated with onboard laser altimetry data, generating digital elevation models (DEMs), digital terrain models (DTMs), and other large-scale 3D mapping products with vertical accuracy of 5 meters. Additionally, the SuperView constellation captures daily stereo imagery with vertical accuracy of better than 2 m.
Hyperspectral Imaging – Imaging in 25 spectral bands spanning the visible, near-infrared, and mid-infrared portions of the spectrum is designed for regional natural resource management: detecting crop stress and planning pesticide/fertilizer applications, species mapping of forests and vegetative land cover, and protecting environmentally sensitive areas. These data sets can also be used in agriculture monitoring, mineral exploration and water-quality monitoring.
Nighttime Imaging – Monitoring and surveillance activities by government entities, energy utilities and security organizations can be carried out around the clock with true-color, high-resolution at 1 m optical and video imaging during daylight and dark of night. Nighttime collection is suitable for surveillance such as illegal camping, border surveillance, change detection (especially in rapidly evolving events), powerline incidents and designing streetlight placement in urban settings. Day and night video can detect vehicle and ship movement.
UP42 users have a growing selection of satellite imagery to choose from on the geospatial marketplace. UP42 technical experts are available to assist customers in selecting the best data set to meet the needs of specific end-use applications in all industries and sectors. These experts can also help in tasking a satellite for new image acquisition or querying the archive to obtain existing imagery.
Spire Global, a global provider of space-based data and analytics, has announced the continuation of its participation in NASA’s Commercial Smallsat Data Acquisition (CSDA) Program with a $6 million contract extension.
The contract continuation, Task Order 6 (TO6), is a subscription data solution that includes radio occultation (RO) data, grazing angle GNSS-RO, total electron content (TEC) data, precise orbit determination (POD) data, soil moisture and ocean surface wind speed GNSS reflectometry (GNSS-R) data and magnetometer data.
This data will be available to all federal agencies, NASA-funded researchers and, more broadly, to all U.S. government-funded researchers for scientific purposes.
Under CSDA Program TO6, Spire will deliver a comprehensive catalog of data, associated metadata and ancillary information from its Earth-orbiting small-satellite constellation. The company operates its constellation in low Earth orbit and collects upwards of 10,000 radio occultations per day with consistent global coverage.
For TO6, Spire will provide rolling access to 12 months of radio occultation data with a 30-day latency. This data will be archived and maintained by NASA under the CSDA Program’s SmallSat Data Explorer (SDX) database.
“Programs like CSDA highlight the incredible potential of private-public partnerships in the federal government to drastically accelerate our ability to confront some of the greatest challenges of our time, such as climate change,” said Peter Platzer, CEO of Spire. “With the end-user license agreements, our data is now available to all federal agencies and the larger NASA scientific community to help support Earth observation research across fields.”
The program includes end-user license agreements (EULAs) to enable broad levels of dissemination and shareability. All federal agencies and U.S. government-funded researchers will have access to Spire’s data for scientific purposes under TO6 and will be able to request access to the data via the CSDA Program’s Commercial Datasets webpage.
“At NASA, the CSDA Program has continued to blossom as a valuable resource to our team for our Earth observation research and analysis. We are committed to growing the program as well as continuing the work we have started,” said Will McCarty, project scientist at the CSDA Program and research meteorologist at NASA Global Modeling and Assimilation Office. “Spire has been a valued partner through CSDA’s development since its inception, and with this additional task order, we are excited about the new insights and results that will come not only from within NASA, but also through broader collaboration through the domestic government scientific community.”
NASA has used Spire data in its research on water and sea-ice levels in the polar regions, the height of the planetary boundary layer (PBL), and the day-to-day variability of thermospheric density at flight level.
NASA also noted that Spire data has shown positive benefit to its GEOS Atmospheric Data Assimilation System, which uses space-based data to analyze the Earth’s atmosphere and assimilate the data into its Earth observation systems.
As one of the original vendors for the CSDA Program, Spire provides NASA yearly updates to the scope of work under this agreement to ensure alignment of data to the agency’s needs.
“Crime is common. Logic is rare. Therefore, it is upon the logic rather than upon the crime that you should dwell.”
“Data! Data! Data!” He cried impatiently. “I can’t make bricks without clay.”
— Sherlock Holmes, “The Adventure of the Copper Beeches,” Sir Arthur Conan Doyle
Watson is to Holmes what information is to intelligence. Watson could listen to the client story, observe the situation, and recite to Holmes all the relevant facts, but he lacked the ability to string together the seemingly random pieces of information into a coherent chain of events leading to the correct hypothesis. A computer can become a Watson, but it takes a human to be Sherlock; however, a human misguided by cognitive biases will end up as Inspector Lestrade, always coming to the wrong conclusion.
When it comes to data, the analogy of drinking from a fire hose is an understatement. Consider that a digital image can be terabytes in size and every day millions of images are taken. Facebook generates 4 petabytes of data daily, and each day there are 500 million tweets and 306 billion emails. Additionally, there are 20 billion connected devices. Combined, the world creates 2.5 quintillion bytes of data every day. If a grain of sand represents a byte of data, then every three days more data is created than there are grains of sand on the Earth, and it is only increasing.
Somewhere in all that data are signals. Real-time threat intelligence systems are looking for those signals before the next huge event occurs. It is a high-stakes hunt for Leviathan, except that Leviathan is only a packet of sand traveling at lightspeed through a cloud obscured by dust.

Interpreting a Signal
The massive volume, variety and velocity of continuously flowing data far surpasses the ability of humans to process. It exceeds the bandwidth most systems can handle. And it quickly overwhelms the capacity to store, manage and act on the information in a timely and cost-effective manner. Resources are not infinite. The best model to handle an overwhelming amount of data is the human brain. Humans are biological sensors. Every moment of every second of our lives, our bodies are receiving an endless stream of stimuli from internal and external sources. Most of this stimuli registers at an unconscious level, and as long as the stimuli is normal and expected, it goes unnoticed by the conscious mind. If, however, any discomfort is experienced, the conscious mind is notified. Then that becomes the focus until normalized. Externally, the same applies to computer data systems. Normal conditions are ignored, but if there is something unusual, such as a loud constant noise, or a colder than normal temperature, it draws all the processing attention.
In the realm of intelligence that is basically how things function. Algorithms are written to learn the normal patterns of life and to identify specific events, words, names, etc. As long as data is within normal parameters, it gets little attention, but as soon as an anomaly exceeds a threshold or something triggers the algorithm, it will immediately be brought to the attention of the intel center. An example can be viewed on the Global Incident Map dashboard. I encourage you to sign up for a free 72-hour membership. If you want to see what real news looks like, this would be a sampling. The number of real incidents that happen across the country and around the world that you never hear about, many of them hair-raising and all of them open source, add to the few stories the media has been able to tell about cyber attacks. Scroll down the page. There are many filters, but I recommend turning them all off to see the full extent of information. Clicking on an incident will drill down into the actual source so you can read about it more thoroughly.
Below is the U.S. Army’s real-time critical incident dashboard called the Joint Analytic Real-Time Virtual Information Sharing System (JARVISS). It tracks and monitors activity near U.S. Army installations and standalone assets of interest around the world.

Fast Analysis in Real Time
Monitoring this information, analysts look for connections. If a plane veers off its flight path, the local operations center is notified. An automatic query shows if any critical-infrastructure assets or other important structures and facilities are in the area. The analyst can immediately find out the type of aircraft, the call sign, who the plane is registered to and who filed the flight plan. Weather radar can be overlaid to see if that is a possible reason for the deviation. Incident reports can be displayed in real time within the area of interest, along with social media feeds and other sources of communication. Traffic patterns can be displayed.
The important question that needs to be answered is whether this is a potential threat. Is there a connection to anything going on anywhere else? A dossier is developed on the person who filed the flight plan, the one who is assumed to be the pilot and the person or organization to which the plane is registered. All of this is being done in a matter of minutes, while the airplane either returns to its flight path or continues its diversion. The air traffic control tower is contacted to share information on the aircraft and its deviation. If the tower does not have an answer, it will radio the pilot for an answer. The passenger and crew manifest also are analyzed. All the data that can be pulled together — including the remaining fuel burn and the aircraft performance limitations — are analyzed.
Patterns emerge from the data. These patterns lead backwards to a cause and forward toward the end result. Finding those clues in the data requires a team of specialists from six primary intelligence disciplines.
An imagery intelligence analyst brings in the live-streams and remote sensing.
A human intelligence analyst seeks motivating factors and ways to deescalate the situation.
A measurements and signatures intelligence specialist defines the operating limitations and the mechanics and science particular to the scenario.
An open-source intelligence analyst accesses and queries open-source data sets to provide clues.
A signals intelligence specialist focuses on the communications and electronic signatures.
A geospatial intelligence analyst brings it all together and provides spatial context through the map the team uses that shows the events unfold in real time.
These analysts and sometimes many others will collect all these pieces of information and turn them into intelligence that decision-makers can use to take action. That is the purpose of intelligence; as CIA veteran Richard Heuer stated, “Intelligence seeks to illuminate the unknown.”
Fortunately, most alerts turn out to be false positives, but every one of them is treated as if it were “the one.” These false positives turn out to be excellent, real-world exercises that hone the skills of the team and wire the brain for speed. These events can last mere minutes or several hours. It’s an adrenaline rush.

Skyward, A Verizon company, has signed a Memorandum of Agreement (MOA) with the U.S. Federal Aviation Administration (FAA) to test cellular-connected drones. Cellular-connected drones could unlock complex operations like beyond visual line of sight (BVLOS), universal traffic management (UTM) and one-to-many operations.
Titled “Unmanned Aircraft Systems (UAS) — Cellular Technologies to Support UAS Activities,” the MOA enables Skyward and the FAA to mutually research the capabilities of cellular communication networks for command and control (C2) within the National Airspace System.
Partially focused on safety-critical C2 data, the three-year MOA also allows the two groups to propose standards for operations, including BVLOS and over commercial wireless spectrum. Skyward and Verizon will also be using the data and information collected in the course of the MOA to inform its discussions on C2 and BVLOS operations in the FAA’s BVLOS Advisory and Rulemaking Committee.
Today, most commercial drones use unlicensed spectrum, which is restricted in range and subject to interference, limiting its use for complex operations. Verizon’s 4G LTE nationwide coverage, provided over spectrum protected from interference, presents an enormous opportunity for drone operations.
The MOA will inform regulations regarding spectrum used in the C2 link between the drone operator and drone. The MOA will also facilitate information sharing between the FAA and Skyward as the parties continue to explore how wireless networks can support drone operations.
The MOA is inspired by the previous industry collaborations with the FAA, but is intended to address complex UAS operations through joint data collection and analysis.
The agreement also follows Skyward’s announced emergency waiver to inspect critical communications infrastructure near the Big Hollow wildfire in Washington in September 2020. The industry’s first known fully remote BVLOS operation with no pilot or visual observer on site demonstrated low-risk operation as well as a need for analyzing and sharing fully remote data with standard bodies and the FAA.
“Cellular-connected drones play a critical role in enabling tomorrow’s safe, reliable and secure drone operations,” said Matt Fanelli, Director of Strategy and Operations at Skyward. “We are thrilled to be laying this foundation with the FAA and are confident that our efforts will help inform technical standards from which industry regulations authorizing low-risk BVLOS and one-to-many operations will flow.”
This is the sixth consecutive year of growth of the journal’s impact factor
The Institute of Navigation announces that its quarterly journal, “NAVIGATION: The Journal of The Institute of Navigation,” has recorded its sixth consecutive year of growth of the publication’s Journal Impact Factor (JIF).
The JIF, an index that calculates the yearly average number of citations to recent articles published in a journal, is considered a bellwether of the relative importance of a journal within its field. A journal with a higher impact factor generally is viewed as being more important than those with a lower impact factor due to its citation rate.
NAVIGATION’s JIF has now increased to 2.1, representing a consecutive seven-year increase.
NAVIGATION’s JIF growth reflects the continued focus and leadership of the Journal’s Editor, Richard B. Langley, who is also the editor of GPS World’s Innovation column. Also key to NAVIGATION’s growth is its editorial board, which includes: Penina Axelrad, Daniele Borio, Michael Braasch, Liang Chen, Pau Closas, James Curran, Naser El-Sheimy, Paul Groves, André Hauschild, Christopher Hegarty, Changdon Kee, Jiyun Lee, Sherman Lo, Gary McGraw, Michael Meurer, Thomas Pany, Boris Pervan, Jason Rife, Andrey Soloviev, Todd Walter, Zheng Yao and Zhen Zhu, and the Journal’s managing editor Lisa Beaty.

Cellular-V2X (C-V2X) is a key technology that will improve road safety and accelerate autonomous driving in the coming years. Specifically, the C-V2X PC5 interface, operating in the 5.9-GHz frequency enables direct, reliable, low latency communication between vehicles (V2V), vehicles and infrastructure (V2I) and vehicles and pedestrians (V2P). For the automotive industry to deploy this technology in a timely manner, cooperation between suppliers in this industry becomes increasingly important, the companies said.
The test cases performed by Rohde & Schwarz and Quectel are designed for automotive companies looking to pre-validate 3GPP system performance in an automated and timely manner before entering OMNIAIR or CATARC certification process. The test system provides a high degree of automation and flexible instrument configuration, which meets the requirements of the automotive industry for C-V2X testing.
A key benefit for customers is the ability to leverage existing investments in Rohde & Schwarz equipment, thereby minimizing additional capital investment.
“Through C-V2X PC5 direct communications, the AG15 will make traffic smoother and more efficient by paving the way for automated driving and achieving the goal of fully connected traffic,” said Manfred Lindacher, VP Global Sales Automotive International, Quectel Wireless Solutions. “We’re delighted to have collaborated with Rohde & Schwarz to validate these test cases and are looking forward to helping our customers on the road to build a smarter world with our automotive grade C-V2X modules.”
A team with Stanford University’s Center for International Security and Cooperation (CISAC) used BlackSky’s geospatial imagery and burst collection technology to track and monitor activity at a secretive Iranian nuclear facility in a new intelligence study. The study tracks and monitors activity at the Natanz nuclear facility in Iran.

“The BlackSky/CISAC research team demonstrated the power of combining rapid revisit satellite imagery, human domain expertise and AI/ML (artificial intelligence/machine learning) techniques to identify and understand activity at Natanz, which was previously unknown to much of the world,” said Patrick O’Neil, chief data scientist at BlackSky. “Observations that provide real-time, activities-based insights have the potential to change the world.”
BlackSky’s high-revisit satellite imagery enabled researchers at Stanford University’s Center for International Security and Cooperation (CISAC) to monitor the pattern of life at the Natanz nuclear facility and gain a better understanding of activity and events at the site.
BlackSky’s satellites provide high, intraday revisit capabilities, allowing CISAC’s research team to receive multiple images a day, throughout the day, rather than just one image collected at roughly the same time each day.
BlackSky satellites are also capable of capturing a sequence of up to 20 images within a matter of minutes, known as a burst collection, and then splicing them together. Instead of a single picture, burst collections are geospatially normalized and joined together to generate a moving sequence of activity. With BlackSky’s assistance, the research team was able to witness trucks emerging from the facility’s underground tunnels.
Allison Puccioni, a renowned imagery analyst and BlackSky consultant, assembled a research team at Stanford University, with help from Rose Gottemoeller, diplomat, former NATO deputy secretary, and visiting professor at Stanford. The pair enlisted two principal research assistants in geospatial science to develop a sophisticated situational-intelligence program to monitor the Natanz nuclear facility.
Natanz is Iran’s primary facility for advanced uranium enrichment and is an active political and military location driven by concerns about the country’s nuclear operations.
