    Depending on your age, 30 years represents a varying opinion of time. For some, it may seem like forever; for others, it may be a blink of an eye. In respect to technology, it can represent a complete change in the way we do things.

    When we turned the calendar page to January 1990, our world had yet to experience the internet, the Hubble telescope had not been deployed to share its fantastic views, and The Simpsons television series was preparing to become the cartoon juggernaut it remains today.

    Yes, lots has changed since 1990, and surveying is no exception.

    Most professions look back through their history and see various periods where discoveries and inventions revolutionized how the work was completed.

    For surveyors, the past 30 years have contained more advancements than all other years combined, with the greatest achievement being the global navigation satellite system (GNSS). With the United States leading the way with its Global Positioning System and the civilian ability to use this measuring system, modern surveying was forever changed.

    Solar and lunar observations replaced

    Before the implementation of a satellite navigation system, true global navigation was only computed using solar and lunar readings under specific conditions. GPS provided a new frontier for surveyors to establish positions without having to perform traversing from known points or collecting solar/lunar observations.

    As the constellation grew, it became easier to use GPS to gain initialization for accurate and redundant position determination. As processor speeds and data storage capability increased, real-time kinematic (RTK) observations became the norm for surveyors everywhere.

    The Russian satellite constellation, GLONASS, began operating fully in the late 1990s, and is now included to create today’s GNSS. More satellites provide more coverage, which in turn means more data collection potential.

    Many nations and regions are building their own constellations to augment the current GNSS lineup, and also to safeguard the ability to obtain geographic locations when other systems are not available.

    Bathymetric surveys made easy

    GNSS capability and integration revolutionized several aspects of surveying, including a new and more reliable way of performing bathymetric surveys over large bodies of water. Computerized depth sounders were programmed to coincide readings with GNSS data collection to provide a more accurate and precise method of hydrographic surveying.

    The past decade has continued the reliance on GNSS technology with many more devices and applications — not just for the surveyor, but for the public as well. While surveyors are using GNSS receivers on unmanned vehicles such as UAVs and boats, satellite navigation has infiltrated into many of our everyday routines. Cellphones, fitness trackers and our automobiles use this technology to guide us to our destinations.

    Surveyors have used the GNSS revolution to create a digital world for better data collection, asset management and increased efficiency. Much has changed in 30 years for the surveyor and the world around us, so we should not be surprised about what technology will bring us next.

    Random recollections of GPS/GNSS

    GPS had been around for about five years before first launch in February 1978 and Full Operational Capability (FOC) was eventually declared in April 1995. It takes time to develop, field and prove something as complex as the world’s first satellite navigation system. But we’re now well into a third generation of the venerable GPS, with GLONASS, Galileo, BeiDou and IRNSS/NavIC and QZSS around the world and in geographic locales. So, putting aside Transit or anything else, this would make GPS about 47 years old — heading into middle age.

    Therefore, it would seem that Glen Gibbons waited until “this GPS thingy” looked like it might actually work — circa 1990 — to launch GPS World, since the magazine is now 30 years old and is also into its third-generation of editor-custodians! Alan Cameron bravely carried the flag after Glen and nurtured the magazine for a good number of years and brought me into the fold as a contributor. We shared ION GNSS conventions and GPS World Leadership dinners and he was able to cajole monthly articles out of me for many years. Now Marty Whitford has his hand firmly on the tiller as publisher, with Tracy Cozzens as senior editor.

    So what went down during these decades of technological advancement and for many of the people in the satnav industry? It would be impossible to answer within my word-limit, so I’ll take on an extremely small subset and recount a few things I can still remember.

    µGPS. I got into GPS around 1990 in an OEM board-level product spin-off program from a certified GPS airborne receiver at CMC in Montreal — we initally called that L1 receiver µGPS because then it was a small GPS board. Later it became known as the AllStar receiver. We found pretty neat applications for the early ’90s — golf-course systems, vehicle tracking, airport vehicle tracking, the start of vehicle nav systems and such.

    At NovAtel in Calgary in the early ’90s, we watched things develop through L1/L2 dual frequency, began RTK market applications in survey, geographic information systems (GIS), agriculture, mining and all multitudes of attempts to get new companies off the ground.

    WAAS. Eventually the U.S. Wide-Area Augmentation System (WAAS) program came and swallowed us up through three different prime contractors. Once that Federal Aviation Administration program was running well, we were into programs in Europe, Japan, India and China, and that led into Galileo ground reference receivers. The software qualification work we did on Galileo positioned us to take on mil-spec receiver work, and even anti-jam products.

    Then CMC bought NovAtel, and we also joined with CMC to develop a certified airborne receiver. In 2003, NovAtel bought the AllStar OEM product line from CMC — funny how things work out! The joint certified receiver program eventually resulted in a new generation of high-accuracy airborne sensors. We again changed hands in 2007 when Hexagon bought us, and then NovAtel began working closely with Hexagon subsidiary Leica on survey applications. Many new and interesting developments are still going on there.

    Nowadays, my interests lie with assisted GNSS and with Rx Networks in Vancouver, which I support and advise. Assisted GNSS comes in many forms, has many avenues in the marketplace, and presents its own unique challenges.

    As GPS has evolved into GNSS and into so many, many applications, companies have come and gone but the core of people who drive the industry has grown and acquired new and specialized skills, developing ever more capable technology and products. Even after 47 years of the industry and 30 years of GPS World, we aren’t anywhere close to done.

  • Our insatiable appetite for GPS

    Like the internet before it, GPS started as a niche technology and became a universally recognized one, though much misunderstood and often taken for granted. Both systems originated in the U.S. Department of Defense (DOD) to support military missions, and then exploded into mass-market civilian technologies. While the internet passed from military to civilian hands very early in its history, GPS is still operated by the U.S. Air Force, making it a unique experience for the DOD: a system for which it is responsible that has orders of magnitude more civilian applications and users than military ones.

    GPS has transformed entire professions — most notably, surveying; created new industries — such as ride sharing; boosted innumerable fields of scientific research — from archaeology to zoology; facilitated many aspects of everyday life — such as finding retail outlets and getting there; and given an advantage to U.S. military forces. One application discussed 30 years ago that has not yet lived up to its promised return on investment is precision agriculture.

    Challenges and debates that loomed large in the early days turned out to be growing pains —most notably, Selective Availability (SA). In 1990, Javad Ashjaee reflected the attitude of much of the GPS industry and user community when he said, “I can’t think of a word to say how bad it is.” Other debates have proven more persistent — such as the interference threat posed by LightSquared, reborn after bankruptcy as Ligado Networks.

    GPS first drew considerable publicity in the wake of Desert Storm, when it became the subject of television features, newspaper reports, and special sections in the pages of recreational catalogs. “Ironically,” Brad Parkinson pointed out in September 1994 in GPS World, “civil companies [such as Garmin] developed most receivers used in Desert Storm, with no help from military sponsorship.” Later that decade, while most people were finally aware of GPS technology, it began disappearing deep into its applications and the systems that use it.

    In September 1991 — three and a half years before U.S. Air Force Space Command declared the system’s full operational capability (FOC) on April 27, 1995 — in a speech to the International Civil Aviation Organization in Montreal former FAA Administrator James B. Busey said: “I want to emphasize that we fully support the eventual replacement of [GPS] by other systems — and we are certain that will happen.” That may still happen, in the distant future. However, what Busey did not foresee is that GPS became but an element, though a key one, in a much larger positioning, navigation and timing (PNT) system. This worldwide system includes three other GNSS and two regional ones, several publicly and privately operated augmentation services, and a wide range of complementary and alternative technologies. These include inertial navigation (which has advanced much in the past three decades) and RF signals of opportunity. It may soon include navigation signals from non-GNSS satellites, eLoran, enhanced distance measuring equipment, and Earth-fixed navigation using very low frequency.

    I began my current career in geospatial technologies exactly 20 years ago, as this magazine’s managing editor, just a few months after the end of SA increased GPS’ accuracy by an order of magnitude, and equally expanded the number of its potential applications. Yet today, I still marvel at how pervasive this technology has become and how much further it will transform our lives.

    I will end with a quote from an early GPS World columnist, Hale Montgomery, who wrote in October 1991, “GPS users show an insatiable appetite for ever more precise data. Give them a mile and they want an inch.”


    Seeking back issues: I have the entire collection of GPS World’s print edition, except for the first issue, the 10 issues in the second year (1991), and the September through December 1993 issues. I would be thrilled to receive those missing issues, or facsimiles, from anybody who has them. Email [email protected].

  • No silver bullet for US PNT: Many sources needed

    No silver bullet for US PNT: Many sources needed

    Many PNT sources from multiple providers needed


    “We cannot have GPS signals be a single point of failure for transportation and other critical infrastructure sectors. More safety applications will depend on PNT in the future. Public confidence in these will be critical.

    “People will not be comfortable getting into an automated vehicle or with platooning driverless trucks heading down the highway if they think that their invisible hand is not reliable and that their GPS might be spoofed.

    “Getting public adoption of other PNT capabilities — space-based, terrestrial, and self-contained — integrated with GPS technology will be critical to the success of any such system.”

    — Diana Furchtgott-Roth, Deputy Assistant Secretary for Research and Technology, U.S. Department of Transportation, Nov. 20, 2019, Edinburgh, U.K.

    A Single Point of Failure

    The Department of Transportation (DOT) is responsible for leading civil positioning, navigation, and timing (PNT) issues for the United States. At the moment, the U.S. GPS provides the vast majority of PNT services in the U.S. and around the world. Yet, like all space-based systems, its signals are weak and very vulnerable to interference.

    A recent example of how dangerous that can be in automated transportation systems was revealed recently in an accident report released by the British government. Interference from an unknown source caused a 15.5 kg drone to get away from its operator and crash. Fortunately, no one was hurt. The report cited analysis showing that such a weight could have easily killed someone on the ground.

    Even more concerning, GPS signal characteristics are well known and therefore easy to imitate. Thousands of cases of “spoofing” have been documented with government and malicious actors causing receivers to report they are far from their actual location. In the worst cases, this can cause accidents or enable criminal acts.

    One result of all of this is the President of the United States issuing an Executive Order encouraging “responsible use” of PNT systems. It also directs steps to encourage development and adoption of alternative systems. This includes a White House-level plan for research and development of non-Global Navigation Satellite System (GNSS) PNT.

    In Europe the European Union (EU) has warned that space based PNT alone is insufficient for “…critical applications requiring continuous availability and fail-safe operations.” The EU has also established a monitoring system to detect sources of GNSS interference, and the European Space Agency (ESA) has established an on-going program funding study of both space and terrestrial alternate PNT systems.

    Multiple Cooperating Systems

    The ultimate solution, though, according to senior government officials, will be development and use of many diverse PNT systems working together to ensure users have what they need when and where they need it.

    Image: DOT

    The National PNT Architecture, jointly developed by the US departments of Defense and Transportation, envisions a multitude of PNT sources ranging from GNSS provided by national governments, to inertial and clock suites acquired by users as needed.

    “Many people are fond of talking about a GPS backup,” said one administration official.

    “It’s more appropriate to use the plural ‘backups’ since one system isn’t going to meet everyone’s needs. Even GPS doesn’t meet everyone’s needs which is why we require complementary PNT capabilities.”

    The idea that multiple redundancies are required for an essential function as long been a core principle of systems engineering. This is clearly foundational in the National PNT Architecture.

    It is also a feature in more recent documents.

    One example is the U.S. Department of Defense’s (DoD) PNT strategy publicly released in August of last year. It envisions use of a multitude of systems as a way of “Ensuring a U.S. Military PNT Advantage.”

    Image: DOD
    Image: DOD

    It categorizes these in three layers. A global layer of GNSS and other satellites, a regional layer that includes STOIC and eLoran, and a local/autonomous layer populated by inertial, clock, lidar, radar, scene matching and beacon-based systems.

    Another project taking the architecture approach is described in detail by the recently completed MarRINav report. Sponsored by the European Space Agency, it analyzed the PNT needs of maritime commerce in the United Kingdom.

    The project concluded that a “hybrid approach” using GNSS, eLoran, and the short-range R-mode VDES would be the best and least expensive combination for maritime. It also recommended a local navigation system such as Locata for port cargo operations. The study found that such a combination of systems would also benefit other transportation and infrastructure sectors.

    Implementation

    Yet identifying solutions is often much easier than making them happen. Especially for national projects with dozens of stakeholders. Stakeholders who may often have competing interests. And there is always the question of “Who pays?”

    In the United States both the Congress and the executive branch of the U.S. government are addressing these issues, and in potentially complementary ways.

    Congressional Mandates. With GPS as the cornerstone, both the DoD strategy and the National PNT Architecture show the need for one or more complementary systems to “overcome PNT capability gaps, predominantly resulting from the limitations of GPS.”

    According to one senior official close to the issue, these systems need to be, “integrated with GPS and each other” and within the U.S. “serve all parts of the country — urban, rural, wilderness — even coastal maritime areas.” The idea being that they will constantly reinforcing GPS services while also serving as a safety net for users when during GPS disruptions.

    The National Timing Resilience and Security Act of 2018 requires DoT to begin filling this layer in the National Architecture by the end of this year. The law, passage of which was overwhelmingly supported by both parties, mandates the department establish a difficult to disrupt, wide area, terrestrial timing system to backup (and complement) GPS timing signals. The system also must be expandable to provide navigation services. Even as a timing service, though, it has the potential to make navigation more reliable. Studies have shown that combining such a timing signal with GPS and other GNSS signals can dramatically decrease users’ vulnerability to jamming and spoofing.

    The law also enables the system or systems to be established by leveraging commercial entities and expertise through cooperative agreements, public-private partnerships, and similar arrangements. These tend to be the most expeditious and least costly methods for putting such services in place. As such, they are expected to be very attractive to government program and contracting officials.

    On military side, the in-process National Defense Authorization Act for 2021 requires DoD to quickly complete this part of their architecture also. Hinting that the department has failed to respond to combatant commanders “Joint Urgent Operational Needs,” it directs DoD to provide warfighters non-GPS PNT by 2023. It also directs the department to “enable civilian and commercial adoption of [these] technologies and capabilities”.

    Presidential Order. The administration’s approach is outlined in a February 2020 presidential Executive Order. The order focuses on commercial entities that contract with the government, critical infrastructure, and research and development.

    It calls for, within the next 24 months, agencies to “develop contractual language for inclusion … n the requirements for Federal contracts … with the goal of encouraging the private sector to use additional PNT services and develop new robust and secure PNT services.” The hope is that these new services will be adopted beyond just those companies who routinely serve government needs.

    The departments of Energy, Transportation, and Homeland Security are also required to publish plans on how they will engage various critical infrastructure sectors to evaluate the degree of responsible use of PNT by each.

    Also, the White House Office of Science and Technology Policy (OSTP) is tasked to “coordinate the development of a national plan… for the R&D and pilot testing of additional, robust, and secure PNT services that are not dependent on global navigation satellite systems (GNSS).” OSTP has already begun this and is seeking input from the public.

    Competition and Many Players

    Because PNT user needs are so varied and nuanced, most industry observers see growing opportunities for existing and potentially new providers.

    “Systems and equipment that improve GNSS services, or that complement and augment GNSS are likely to find ready markets,” said Andrew Bach, a consultant on financial and other PNT issues. “User demands and needs are only going to become more sophisticated as their economic exposure increases.”

    Congressional and administration focus on alternative PNT should enhance and multiply such opportunities. So, while there may be no silver bullet for solving national PNT concerns, the need for a robust and resilient architecture of PNT systems will likely mean abundant opportunities for providers.

    When I was a kid in the 1960s, I was entranced by the vision of the future offered by science fiction books, movies, television shows and comics. Advances in technology would deliver us so many wonders — flying cars, hoverboards, robot servants. Disneyland was in on it, with an entire section of the park named Tomorrowland and its now-quaint “Carousel of Progress” attraction.

    But the coolest thing would be that jetpack. You could slap it on your back and take off into the atmosphere, traveling wherever you wished like a bird. Certainly by the distant year 2020, we would all be jetting around the atmosphere from place to place.

    (It didn’t occur to me that would mean strapping an actual jet engine to my body, along with highly flammable jet fuel. Where’s the fun in that?)

    Decades later, we’ve all arrived in the “future,” with personal jetpacks nowhere in sight. What gives?

    Then again, what I didn’t imagine in our future was a system that could pinpoint my exact location anywhere on the globe, estimate my time of arrival, and tell me about the traffic up ahead.

    Back in the 1960s, that was seriously science fiction. Nor did we accurately predict the effect that capability would have on our daily lives. GPS along with internet-capable smartphones have thrust us into the Information Age.

    The internet is a promise delivered, in its own way. Having a repository for all of the world’s information was another future concept, but usually envisioned with a giant worldwide computer that eventually turned on its makers.

    As for flying cars, we are gradually getting there. Drone technology, supported by GNSS technology for its navigation, has led to unmanned craft and is heading toward vehicles capable of transporting people. We just need to be a little more patient.

    In the spirit of looking back and ahead, check out our 30th Anniversary Supplement, which arrived with this issue. In it, experts from across the industry share memories and thoughts, and gaze into their crystal balls to predict the future of GNSS.

  • How companies are using alternative PNT

    How companies are using alternative PNT

    Not just supporting players, alternative positioning, navigation and timing (PNT) systems strengthen, augment and — when needed — replace GNSS. We explore how companies are using alternative PNT, and talk with John Fischer of Orolia and Alexis Guinamard of SBG Systems about their companies’ latest developments.

    Since the 1990s, GPS has provided the United States military with a substantial tactical edge. Civilian GPS applications are now deeply embedded in every aspect of our lives. The U.S. Department of Transportation recently reaffirmed that GPS’ positioning, navigation, and timing (PNT) services are critical to the safe and efficient use of the national transportation system, and a Feb. 12 presidential executive order declared that satellite-based PNT services “have become a largely invisible utility for technology and infrastructure.”

    It has long been equally well known, however, that GPS is vulnerable to accidental and intentional interference (the latter known as jamming), spoofing, and degradation or denial of signals. Additionally, GPS satellites are increasingly vulnerable to damage or destruction by space debris or intentional attack. The executive order mentioned above declared it U.S. policy “to ensure that disruption or manipulation of PNT services does not undermine the reliable and efficient functioning of [the country’s] critical infrastructure.”

    Protecting PNT requires not just strengthening GPS, but also developing alternative sources of PNT data and ways to integrate them into the myriad systems that currently rely on GPS.

    The National Timing Resilience and Security Act of 2018 (passed by the U.S. Senate as part of that year’s Coast Guard authorization act), called for “a complement to and backup for” the GPS timing component “to ensure the availability of uncorrupted and non-degraded timing signals for military and civilian users in the event that GPS timing signals are corrupted, degraded, unreliable or otherwise unavailable.” It mandated the procurement of a wireless, terrestrial system that would provide wide-area coverage and be synchronized with UTC, resilient and extremely difficult to disrupt or degrade, able to penetrate underground and inside buildings, and capable of deployment to remote locations.

    A report released on April 8 by the Department of Homeland Security (DHS), however, recommends “that responsibility for mitigating temporary GPS outages be the responsibility of the individual user and not the responsibility of the federal government.” It points out that research by one of DHS’ agencies “shows that users can mitigate short-term GPS disruptions (e.g., inability to read a GPS signal) with various strategies, ranging from using local backup capabilities to delaying operations until GPS is restored.” The report then focuses on “mitigation against long-term or permanent disruption or loss of GPS PNT capabilities.” It determines that the PNT functions in critical infrastructure “are so diverse that no single PNT system, including GPS, can fulfill all user requirements and applications” and notes that maximum resilience is found in diversity of solutions. Therefore, it recommends that the federal government “encourage adoption of multiple PNT sources [to expand] the availability of PNT services based on market drivers.”

    In the interviews below, I discussed these challenges with John Fischer, vice president of Advanced R&D at Orolia, and Alexis Guinamard, chief technical officer of SBG Systems.

  • GPS celebrates 25 years of operation

    GPS celebrates 25 years of operation

    “Celebrating this anniversary gives us a moment to recognize how far we’ve come, but also to get pumped about what lies ahead for our program and our role in executing that.”


    By  First Lieutenant Tyler Whiting
    Peterson Air Force Base, Colorado

    The Global Positioning System marked its 25th year of operation on April 27.

    On this date in 1995, the system reached full operational capability, meaning the system met all performance requirements.  U.S. Air Force Space Command formally announced the milestone three months later.

    “This is a major milestone,” Gen. Thomas S. Moorman Jr., former Air Force Vice Chief of Staff, said in 1995. “GPS has become integral to our warfighters and is rapidly becoming a true utility in the civilian community.”

    Initially developed for the military to meet a critical need for determining precise location on the battlefield, GPS has also become an integral part of technology affecting the lives of billions of people worldwide.

    “The United States Space Force’s continuing objective for the constellation is to ensure GPS remains the Gold Standard for global space-based positioning, navigation and timing,” said Gen. Jay Raymond, USSF Chief of Space Operations, and U.S. Space Command Commander.

    Image: USAF
    Image: USAF

    Today, the U.S. Space Force operates the GPS satellite constellation as a global utility – always available to everyone, everywhere on Earth.

    “GPS is a free for use service provided by the Space Force that enhances everyday lives around the world,” said Brig. Gen. DeAnna Burt, USSF Director of Operations and Communications. “GPS provides the highest accuracy positioning and timing data.  In addition to the essential capabilities it provides for the military, GPS underpins critical financial, transportation and agricultural infrastructure.  It’s always available, whether for an ATM transaction or securing a rideshare.”

    Military capabilities

    Its military capabilities first enhanced combat operations in 1990 and 1991 during Operations Desert Shield and Desert Storm. Allied troops relied heavily on the new GPS signal to navigate the featureless deserts in Kuwait and Iraq.

    In the early 2000s, during Operations Enduring Freedom and Iraqi Freedom, GPS contribution to warfighting increased significantly.  For example, the GPS constellation enabled accurate munitions, allowing the delivery of GPS-aided Joint Direct Attack Munitions with pinpoint precision and minimal collateral damage.

    Today, in addition to these and other GPS-enabled warfighting capabilities, Airmen conduct resupply missions with battlefield precision airdrops to combat forces with GPS-guided, parachute-delivered equipment pallets known as “Smart Pallets.”

    Continually updated

    The GPS operational constellation currently has 31 satellites, and the system is continually updated and modernized, making it a resilient system to maintain the signals required for accurate positioning, navigation and timing around the world.

    The first satellite of the new GPS III version, called Vespucci, was launched into space Dec. 23, 2018.

    The 2nd Space Operations Squadron at Schriever Air Force Base, Colo., operates GPS. The squadron recently accepted control of the second GPS III satellite, called Magellan, on March 27.

    GPS III is meeting users’ emerging needs and responding to tomorrow’s threats with improved safety, signal integrity and accuracy. GPS III satellites are more accurate, have improved anti-jamming capabilities, and have doubled the design life; when compared to previous iterations of GPS. They are also designed to incorporate new technology and changing mission needs,

    “The 25th Anniversary is a huge, momentous occasion for us. We take great pride in providing this global utility to the approximately six billion users worldwide,” said Lt. Col. Stephen Toth, 2nd SOPS commander. “Celebrating this anniversary gives us a moment to recognize how far we’ve come, but also to get pumped about what lies ahead for our program and our role in executing that.”

    We’ve come a long way since the inception of GPS. Today, location often is taken for granted, but that’s true of every mainstream technology.

    It’s absolutely remarkable how far the technology has evolved. From receivers that were as big as backpacks to tiny chipsets supporting multi-constellation dual-band GNSS receivers in smartphones with antennas that are etched into the body of cell phones, it’s really an amazing technology.

    I’ve had the privilege to work on GPS in phones since before “smart” appeared in front of them. And it’s truly amazing to see how “GPS has revolutionized our day-to-day lives.” But this is not my quote.

    In January at the Google campus in Mountain View, California, we hosted Dr. Brad Parkinson (widely known as the Father of GPS) who gave a talk on this subject. He was the one who called this a revolutionary technology, and that had been a stealthy revolution. Frank van Diggelen secured Brad to come to Google to give this talk.

    His talk was titled “GPS for Humanity.” In the talk, available on YouTube (see below), Brad goes over first hand how, over the past 30 years, this new utility came into being. It came into the fabric of our worldwide society, creating dependencies that did not exist before.

    He detailed how GPS was created, what technologies were essential to its success, all the various ways that GPS keeps crucial processes intact, and how it supports a $1.4 trillion economic impact that this system brings us today.

    It was a privilege and honor to have Brad give a candid and timely talk, and I hope you enjoy it as much as we did!

  • BAE Systems to get Collins GPS and Raytheon ATR businesses

    BAE Systems to get Collins GPS and Raytheon ATR businesses

    Logo: BAE SystemsBAE Systems Inc. has reached definitive agreements for the proposed acquisitions of Collins Aerospace’s military GPS business and Raytheon’s Airborne Tactical Radios (ATR) business.

    The two high-performing businesses are being sold in connection with obtaining the required antitrust clearances for the previously announced pending merger between Raytheon and United Technologies Corporation (UTC).

    The proposed acquisitions are structured as asset transactions with associated tax benefits, and they remain subject to customary closing adjustments. The asset purchase agreement for the Collins military GPS business calls for cash of $1.925 billion, with an expected tax benefit of approximately $365 million. For Raytheon’s ATR business, the purchase agreement calls for cash of $275 million, with an expected tax benefit of approximately $50 million.

    “As militaries around the world increasingly operate in contested environments, the industry-leading, battle-tested products of these two businesses will complement and extend our existing portfolio of solutions we offer our customers,” said Jerry DeMuro, CEO of BAE Systems, Inc. “This unique opportunity to acquire critical radio and GPS capabilities strengthens our position as a leading provider of defense electronics and communications systems, and further supports our alignment with the modernization priorities of the U.S. military and its partners.”

    These proposed acquisitions are subject to the successful closure of the Raytheon-UTC transaction, as well as the satisfaction of other customary closing conditions, including receipt of the required U.S. regulatory approvals. Upon closure, both business lines would be integrated into the company’s Electronic Systems sector.

    “These are strong businesses with talented employees who share our focus on quality and technology innovation,” said Tom Arseneault, president and COO of BAE Systems Inc. “We are confident of a smooth transition that will accelerate our future together and look forward to welcoming these new employees to the BAE Systems team once the transactions are approved.”

    New app gives field crews a fast, easy way to record information while mobile

    Esri has released ArcGIS QuickCapture, a mobile app designed for rapid and at-speed field data-collection workflows.

    Data can be collected from a moving vehicle with the touch of a button and sent back to the office for real-time analysis, leading to faster and more effective decision-making. The new app is designed for road inspections, aerial surveys, monitoring vegetation encroachment and more.

    ArcGIS QuickCapture allows users to configure a customized interface that suits their specific project requirements, eliminating unnecessary features and options. This personalization helps users take advantage of the single-tap, big-button system to capture details and photos as they go. The app is intuitive and user-friendly, eliminating the need for extensive crew training.

    The new app integrates with the user’s existing IT infrastructure and ArcGIS platform, which simplifies implementation. It uses the existing GPS and camera on smartphones and tablets, and it is compatible with iOS, Android and Windows devices.

    For high-accuracy data collection workflows, QuickCapture is also compatible with external GNSS receivers.

    “ArcGIS QuickCapture builds upon and enhances our existing field data collection offerings in ArcGIS,” said Ismael Chivite, senior product manager at Esri. “Field crews are demanding user experiences that are tailored to the way they work. QuickCapture is designed to capture GIS data with the tap of a button, while on the go.

    Following the launch of its Android application in 2018, Geneq is now launching an iOS version of its SXblue ToolBox for iOS-compatible SXblue devices.

    The application was developed with special interest paid to raw data recording and NTRIP service connection.

    With the SXblue ToolBox iOS application, the user can analyze the position data provided by the SXblue receiver, as well as location metadata.

    More important for SXblue clients, the application can record, save and transfer raw data from the GNSS receiver, thereby allowing post-processing activities. The application also acts as a NTRIP client, capable of connecting to a NTRIP server for real-time kinematic (RTK) corrections, and thus allows the receiver to issue very accurate location information.

    Receiver configuration is easy through the application, with the ability to set up and save user-defined commands for subsequent use. The settings include constellation to be used, differential source, NTRIP login credentials list and more.

    In addition, the iOS application includes a series of audible and visual alarms that are user-configurable to determine the thresholds of information provided by the SXblue GNSS receiver.

    The main features of the iOS SXblue ToolBox application are:

    • Display of location information and quality of positioning data
    • Skyplot of all-in-view constellations: GPS, GLONASS, Galileo BeiDou, QZSS, SBAS
    • Recording of raw data and data transfer
    • NTRIP/DIP client to receive RTK corrections
    • Terminal to send commands and view the output data of the SXblue device
    • Audible and visual alarms
    • Activation of options and licenses via the application.
