More than 300 billion rubles ($10.1 billion) have been budgeted to the year 2020 for developing the Glonass satellite navigation system, Deputy Prime Minister Vladislav Surkov said recently. He said the government will make every effort to lend support to the satellite system and to develop its capabilities, including commercial ones, Interfax reported. He said Russia estimates that the navigation market in Russia was worth 12 billion rubles last year.
Many U.S. Military systems, such as missiles, rely on the GPS to provide accurate position, orientation and time information while in flight. When GPS is inaccessible, information critical for navigation must be gathered using the missile’s on-board sensors. DARPA’s Chip-Scale Combinatorial Atomic Navigator (C-SCAN) effort seeks an atomic inertial sensor to measure orientation in GPS-denied environments. Such a sensor would integrate small size, low power consumption, high resolution of motion detection and a fast start up time into a single package. “Platforms such as missiles rely on GPS for a variety of information,” explained Andrei Shkel, DARPA program manager. “When GPS is not available gyroscopes provide orientation, accelerometers provide position and oscillators provide timing. The new C-SCAN effort focuses on replacing bulky gyroscopes with a new inertial measurement unit (IMU) that is smaller, less expensive due to foundry fabrication and yields better performance.”
Raytheon and Lockheed Martin successfully completed the first significant integration milestone between Raytheon’s GPS Next Generation Operational Control System (OCX) and Lockheed Martin’s GPS III satellite system. The joint Lockheed Martin/Raytheon team successfully exchanged satellite commands and telemetry data between the GPS III satellite simulator in Newtown, Pa., and the OCX development site in Aurora, Colo. The integration of the two sites will facilitate development testing of the OCX system and allow early risk reduction testing of the groundsatellite interface in a test-like-you-fly configuration.
As part of the National Space Technology Programme, the UK Government will grant nearly GBP 6 million to co-fund major new research projects that will develop commercial products and services using space technology and data from space-based systems. The grant funding, from the UK Space Agency and the Technology Strategy Board, will support four major research and development consortium projects.
BMC’s Tree Authority is finally catching up with technology: it has decided to use GPS to keep a track of all trees in the city and its suburbs. The civic body hopes that once all trees in the city are identified through their GPS locations, it will become to easier to track their growth and identify if any have been illegally chopped.
Satellite navigation is progressing swiftly, in fact so swiftly that its printed textbooks can’t keep pace – so ESA has introduced its own wiki-based information source, Navipedia, which is also the first ever ESA technical wiki opened to the public. With ESA preparing to launch its next Galileo satellites, ground-based augmentation expanding rapidly, all other Global Navigation Satellite Systems (GNSS) evolving and new satnav applications emerging every day, this website’s launch comes at the right time. Written and reviewed by experts, there are more than 400 articles on the site to date covering the fundamental principles of satellite navigation, how receivers operate, the various systems in current or future operation around the globe and GNSS-related services and applications.
Infineon Technologies has introduced a new series of Receive Front-End Modules for implementation of GNSS functionality in smart phones and other handheld devices. The new BGM104xN7 products feature the best noise figure in the industry, which is a critical parameter for the performance of a GNSS receiver. The new modules are a pin-to-pin compatible upgrade with the previous generation BGM103xN7, and thus remain as the world’s smallest Receive Front-End Modules for this application, with a package size of just 2.3 x 1.7 x 0.73 mm3.
New research shows that for 20% of their running time – 12 minutes every hour – Delhi’s cars are no faster than pedestrians. An ongoing pilot study by the research group UrbanEmissions.info has found that a fifth of a car’s traffic time is spent idling or crawling at less than 4 kmph due to heavy congestion on roads and too many signals. For the study, IIT students equipped with GPS devices drive across the NCR at different hours to collect speed data. So far, they have logged 120 hours on the road travelling to Noida, Greater Noida, Gurgaon, Dwarka and across South Delhi. The plan is to collect data for around 1,000 hours of motoring.
