  • Advanced Navigation releases GNSS/INS post-processing software

     

    Advanced Navigation has released its GNSS/INS post processing software Kinematica.

    Kinematica is designed to be an easy-to-use GNSS/INS post-processing software that allows users to process raw GNSS and inertial data after collection and achieve higher accuracy position, velocity and orientation than is possible in real time.

    Kinematica has been released as free software with a time lock to Aug. 1, 2016.

    The software supports kinematic GNSS positioning, which provides a 200x increase in position accuracy over standard GNSS with 8-mm position accuracy. Dual antenna GNSS heading processing is also supported.

    Kinematica processes data in forward and reverse six times, which allows it to fill any satellite outages and ignore errors that would normally affect a real-time solution. Both loosely and tightly coupled GNSS/INS processing is supported and the software automatically switches between each mode depending upon the environment.

    Kinematica supports all of Advanced Navigation’s GNSS/INS products. Support for a wide range of third-party systems is scheduled for the next update in July.

    Kinematica is targeted at surveying, scanning and aerial photography applications that need to squeeze the maximum performance out of their systems.

  • Eos Positioning announces RTK NTRIP app for Android

    Eos Positioning Systems has introduced a comprehensive RTK NTRIP app for Android that works with its Arrow line of RTK GNSS receivers. An Arrow GNSS receiver combined with the NTRIP app turns an Android smartphone or tablet into a powerful data collector capable of recording 1-centimeter accurate GIS data in real-time.

    “We designed Eos Tools Pro for the RTK user,” said Chief Technology Officer Jean-Yves Lauture. “It is, by far, the most comprehensive NTRIP app for Android on the market today, turning smartphones and inexpensive Android tablets into powerful high-precision GNSS data collection devices.“

    The app, named Eos Tools Pro, has user-configurable audible and visual alarms to alert the user of high PDOP, lost RTK correction, unacceptable correction age and several other important metrics. It supports all current and future constellations (GPS, GLONASS, Galileo and Beidou).

    To eliminate any confusion as to which GPS/GNSS device the user’s app is using, Eos Tools Pro features a dropdown menu so the user may select any receiver the Android device has been paired with.

    “The Eos Tools Pro app enables Android devices running Esri’s Collector app on Android smartphones and tablets to collect data as accurate as 1cm when connected to an Arrow GNSS receiver,” said Esri Product Manager Jeff Shaner. “It’s a big leap forward to enable Collector to serve the high-precision GNSS user.”

    Google Maps is tightly integrated with the app to display the user’s location anywhere in the world. Detailed satellite information such as a skyplot that plots each visible satellite, whether it’s being used or not, and signal strength bar graphs from each constellation are also displayed. Finally, a Terminal screen displays the NMEA data flowing and allows the user to send commands to the receiver.

    Eos Tools Pro and Arrow receivers are targeted at high-accuracy applications like GIS; environmental; agriculture; electric, gas, water utilities; surveying; machine control; and federal, state, and local government.

  • Prime Meridian on the move

    Pre-GPS techniques actually responsible for the Greenwich shift

    By Stephen Malys, John H. Seago , Nikolaos K. Pavlis, P. Kenneth Seidelmann and George H. Kaplan

    The historical prime meridian runs through a telescope established in 1851 by Sir George Airy at the Royal Observatory at Greenwich, England. It was adopted as an international standard as the prime meridian for zero longitude in 1884 during the International Meridian Conference held in Washington, D.C.

    The observatory’s line in the pavement is a major tourist attraction, but the prime meridian used by satellite navigation systems is located 102 meters east of that historic location (see Figure 1).

    Some people mistakenly thought that GPS, or the earlier Navy Navigation Satellite System (Transit), was responsible for this offset. But research, recently published in the Journal of Geodesy, concludes that the zero longitude used by GPS arrived at its current location in 1984, before GPS existed as an operational system.

    The orientation of the World Geodetic System 1984 (WGS 84), and therefore the direction of the prime meridian associated with WGS 84, was established when the U.S. Defense Mapping Agency (now part of the National Geospatial-Intelligence Agency) adopted the orientation of an international scientific standard known as BTS 84, the BIH Terrestrial System 1984.

    The Bureau International de l’Heure (BIH) was a predecessor to the International Earth Rotation and Reference Systems Service (IERS). Unlike previous terrestrial systems of reference used by the BIH, the BTS 84 was not established by tracking stars with optical telescopes.

    BTS 84. BTS 84 was created using geodetic techniques known as satellite laser ranging, lunar laser ranging and very long baseline interferometry. While satellite Doppler tracking (Transit) data was included in the BIH process, this data type did not contribute to or constrain the orientation of BTS 84.

    When an optical instrument is leveled, even to the highest accuracy achievable, its orientation is controlled by the gravity field’s vertical direction at that particular location.

    The astronomical zenith, or “up” direction realized by a telescope, is perpendicular to the gravity equipotential (level) surface locally, and therefore is in general deflected from the geodetic zenith that is perpendicular to our best-fitting global ellipsoid model of the Earth due to small irregularities of the gravity field (hence the term deflection of the vertical, DoV).

    As a consequence, the astronomical meridian plane at an arbitrary location on the Earth does not necessarily contain the center of mass of the Earth (FIGURE 2).

    Astronomical Time. When optical systems were finally retired from Earth-orientation service by the BIH in 1984, the BIH continued the measurement series for Earth’s rotation by modern geodetic techniques, but required continuity in the determinations. These measurements included those for astronomical time, UT1.

    Requiring continuity in UT1 was equivalent to requiring that the plane of the prime meridian keep its orientation, relative to the celestial sphere, as a function of time. But now — for the first time — there was also a requirement to pass this plane through the center of mass of the Earth.That requirement, along with the DoV at Greenwich, moved the trace of the prime meridian on the Earth’s surface in the vicinity of Greenwich by 102 meters to the east of Airy’s telescope (Figure 2).

    Journey to the Center of the Earth.Thanks to satellite-tracking techniques, we now know the location of the center of mass of the Earth with an accuracy of about 1 centimeter in three dimensions — about the size of a U.S. dime.

    In 1984, its location was known with an accuracy of about 1 meter. When Airy set up his special telescope (called a transit circle), knowledge of the size, shape and center of mass of the Earth was limited to several hundred meters.

    The trace of the historical astronomical prime meridian established by Airy’s instrument, and the location of zero longitude indicated by GPS receivers, are both consistent with their own conventions, and their offset from each other does not imply an error in either determination.

  • Silent watchers over Somalia

    The Spanish navy is using UAVs for intelligence operations on the northern and eastern coasts of Somalia to locate possible illegal activities. This past summer, the navy used the Scan Eagle unmanned air system during Operation Atalanta, a European Union mission combating piracy in the Indian Ocean.

    The Scan Eagle system, deployed from the amphibious assault ship Galicia, produced valuable intelligence for the Naval Force of the European Union (EUNAVFOR). The system consists of four aircraft, one of which is designed to acquire night images.

    The Scan Eagle is launched via a catapult, and lands by means of a pole, into which the aircraft is “locked.” A set of antennas sends and receives information between the control station and the UAV.

    The system can operate continuously for more than 18 hours at a stretch, collecting data, images and video both day and night.

    During Operation Atalanta, the Scan Eagles completed more than 175 flight hours, collecting imagery for more than 11 hours without being detected and providing command with real-time images of possible targets.

    The UAV system was also deployed in Afghanistan, where it operated from the advanced support base of Qala i Naw until the withdrawal of the Spanish contingent in 2013.

    The mission represents a milestone for the Spanish navy — the first remotely piloted aircraft operating successfully from a navy vessel.

  • Survey lasers in on Iron-Age archaeology

    High-tech aerial laser surveying is being employed to reveal the hidden archaeology of an Iron-Age hill settlement in Lancashire, England.

    Visually, the archaeological features are difficult to see, but a Bluesky laser survey, commissioned by the Morecambe Bay Partnership, is expected to reveal previously undiscovered details of a settlement at Warton Crag. Identified as an important Heritage at Risk site, the site has already been subject to low-level archaeological investigations, which have identified remains from a small, well defended hill fort.

    “It is imperative that we get a better definition of the archaeological remains that are currently ‘hidden’ by the dense vegetation cover,” said Louise Martin, H2H cultural heritage officer at the Morecambe Bay Partnership. “This will enable us to develop conservation strategies for the site and work towards reducing the risk to the archaeological remains. The site is currently on Historic England’s ‘at risk’ register, so this work is crucial in developing partnerships and strategies to protect the monument for future generations.”

    The Bluesky lidar system uses lasers to accurately measure the earth’s terrain and record features on the ground in 3D. A dedicated survey plane is equipped with aerial photography equipment and will fly over the site during the winter months when the tree and canopy cover is at its minimum.

    Bluesky will process the millions of individual laser measurements to create detailed 3D computer models of the Earth’s relief — a Digital Terrain Model (DTM) — and ground surface including buildings and vegetation — a Digital Surface Model (DSM). This will allow the Morecambe Bay Partnership to model scenarios and strategies and share information with project partners.
