Real-time real-world testbed for new signals By Daniel S. Maier, Thomas Kraus, Daniela E. Sánchez, Ronny Blum and Thomas Pany, Universität der Bundeswehr München This research paper presents an update of the authors’ real-time real-world testbed for new GNSS signals. It includes experience gained in setting up an airborne pseudolite, UAVlite, to analyze the code- and phase-ranging performance and to test navigation... read more
“Seen & Heard” is a monthly feature of GPS World magazine, traveling the world to capture interesting and unusual news stories involving the GNSS/PNT industry. Tethered drone Spanish police used a tethered drone system for traffic monitoring, crowd control and surveillance of the UEFA Champions League Final, played June 1 at the Wanda Metropolitano stadium in Madrid. An Elistair tethered U06... read more
Global markets learned something important from the brown-out of Galileo signals over a week’s time in July: Life goes on without a hiccup in the absence of the European GNSS. Very unfortunately for the backers and boosters of Galileo, this message will reverberate down through the years. If vital affairs proceed unaffected by Galileo’s travails, or triumphs for that matter,... read more
imt.x1 uses u-blox positioning technology to deliver high levels of positioning sensitivity and accuracy. U-blox and Arvento Mobile Systems are launching the imt.x1 vehicle tracking system. The companies previously partnered on the Treyki Mini tracker. Arvento’s imt.x1 has a six-axis gyro sensor that can sense three-dimensional movement caused by emergency acceleration, panic braking and directional yaw and drift. With connectivity options including... read more
Racelogic Ltd. has released the latest update to its SatGen GNSS simulation software for PC, which now incorporates Galileo RF simulation. Designed to create a GNSS RF I&Q or IF data file based on a user-generated trajectory file, the updated software can now accurately simulate the European Galileo GNSS satellite constellation alongside existing GPS, GLONASS and BeiDou RF signal generation. The... read more
L1C Signal Could Be Watermarked as Countermeasure The U.S. Air Force will load a new signal feature, designed to make spoofing detectable, aboard a satellite that will broadcast it from space as a security overlay for the GPS L1C signal, but not until 2022 at the earliest. The Chips Message Robust Authentication (Chimera) is now in testing under the auspices... read more
This just in: a Final Report on the Economic Benefits of GPS. Sponsored by National Institute of Standards and Technology, the study began a couple of years ago, conducted by RTI International, one of the nation’s oldest and largest research firms. The report runs 306 pages and examines the benefits derived from GPS by 10 U.S. industries: agriculture, electricity, finance,... read more
