By Inside GNSSA Soyuz launcher operated by Arianespace and commissioned by ESA lifted off with the pair of 715 kg satellites from French Guiana on December 5. The two join 26 Galileo satellites in the orbiting constellation that now provide Initial Services.
By Inside GNSSJoin Adam Barnes, Head of Product at Advanced Navigation, and Ashley Cox, Chief Operating Officer at Cordel, to find out how the latest LiDAR and navigation technologies are revolutionizing surveying.
In this webinar, Adam and Ashley will deep-dive into LiDAR surveying and explain how Cordel leveraged innovative technology to push the boundaries of the industry. They will cover the challenges in UAV-based surveying, in balancing cost and altitude restrictions, with LiDAR point density and INS accuracy to achieve the best overall solution.
By Inside GNSSRapidly changing motion means that every aspect of positioning must be carefully re-examined and re-evaluated to avoid costly and dangerous positioning errors. The frequent changes in heading, acceleration and deceleration inherent in rockets, missiles, jet planes, race cars and other platforms — up to 100 times per second! — dictate a very high rate of data inputs from both inertial and GNSS sensors to capture the complex trajectory.
By Inside GNSSIn a race with the U.S. to develop a laser communications network in space, China’s BeiDou GNSS has conducted an inter-satellite and satellite-ground station experiment using using lasers rather than the usual radio signals. The technology could potentially transmit data a million times faster than by radio signal to almost any location. Some experts say it could increase satnav accuracy by a factor of 6 to 40
By Inside GNSSFuture miniaturized sensors, to be used for example in bee-sized drones, mini-satellites, or wearable devices, are likely to include GNSS chipsets supporting accurate outdoor localization and also offering reduced computational costs and power consumption compared to traditional GNSS receivers. The survey various energy-efficient methods for GNSS acquisition and present a discontinuous-reception acquisition algorithm, analyzed with both simulated and measurement-based data.
Russia conducted an unannounced direct-ascent anti-satellite (DA-ASAT) missile test on November 15, targeting and exploding its own defunct satellite Tselina-D. After the test, Russian television executive and spokesperson Dmitry Konstantinovich Kiselyov, head of the official Russian government-owned international news agency Rossiya Segodnya, reportedly said on live tv that this demonstrated that Russia could and would if necessary target U.S. GPS satellites, thus “blinding” its military forces.
By Inside GNSSEurope’s first prototype satnav space vehicle, Galileo In-Orbit Validation Element A (GIOVE-A), was decommissioned on November 24 after 16 years of work in orbit. The 2005-launched mission secured Galileo’s radio frequencies for Europe and demonstrated key new space-based navigation hardware.
By Inside GNSSThe U.S. Navy’s Office of Naval Research (ONR) Global announced the winner of its second Global-X Challenge, kicking off a proof-of-concept effort on an alternative navigation system using muons in the Arctic to gain precision equal to that of GPS.
By Inside GNSSSpectranetix, Inc. has released its SX-124, ruggedized 3U OpenVPX high-performance position, navigation and timing (PNT) solution. With an ability to provide timing and positioning information in a GPS-denied environment through sensor fusion, the SX‑124 switch is a highly integrated next-generation cyber / electronic warfare (EW) / Signals intelligence (SIGINT) / Communications / Battle Management System (BMS) device
By Inside GNSSLow Earth Orbit (LEO) satellites are being launched regularly into space to create satellite constellations for a variety of purposes: communication, surveillance, providing Internet service and more. Global satellite navigation service is provided by satellites in higher orbits, mi-Earth orbit (MEO) roughly 25,000–27,00 kilometers above the Earth. Could satellites in LEO be used to provide global satellite navigation?
Telespazio UK, a subsidiary of Telespazio of France and Italy, received a development contract from the European Space Agency (ESA) for a Next Generation Network Assisted Position, Navigation and Timing (PNT) Assurance (NG-NAPA) project.
By Inside GNSSHigh standards for technology in the lab and in the factory are all very fine, but what matters most is how it works in industrial application. We take a close-up look at inertial measurement and inertial navigation in such real-world cases as
• oil and gas pipeline inspection,
• stabilization of optical camera platforms and
• autonomous cargo transport.
