NovAtel, Inc. has introduced the newest member of its OEM6 receiver family: the OEM615. Measuring only 46x71x11 millimeters (1.81×2.79×0.43 inches) and weighing 24 grams (0.84 ounces), the diminutive OEM615 provides precise positioning in a familiar, compact form factor.
By Inside GNSSCiting European Space Agency (ESA) studies that showed “harmful interference” to Galileo receivers operating up to 1,000 kilometers from LightSquared base stations, a European Commission (EC) official has told the Federal Communications Commission (FCC) about his “deep concerns” about the wireless broadband company’s terrestrial transmissions in the 1525–1559 MHz band next to L1 GNSS frequencies.
By Inside GNSSWorking Papers explore the technical and scientific themes that underpin GNSS programs and applications. This regular column is coordinated by Prof. Dr.-Ing. Günter Hein, head of Europe’s Galileo Operations and Evolution.
By Inside GNSSQ: What is a virtual reference station and how does it work?
A: To reach centimeter-level — or even better — accuracy of positioning typically requires use of precise dual-frequency carrier phase observations. Furthermore, these observations are usually processed using a differential GNSS (DGNSS) algorithm, such as real time kinematic (RTK) or post-processing (PP). Regardless of the specific differential algorithm, however, implicit in the process is an assumption that the quality of the reference station data is consistent with the desired level of positioning accuracy.
By Inside GNSSThis officially sanctioned conference and equipment exhibtion addresses applications, technologies and trends for China’s satellite communications, broadcasting, remote sensing, navigation and positioning.It will be held at Hotel Nikko New Century in Beijing on October 26.28, 2011.
Subjects of most interest to Inside GNSS readers include:
By Inside GNSSThe International Symposium on Global Navigation Satellite Systems, Space-based and Ground-based Augmentation Systems and Aplications will take place at the Wilmersdorf in Berlin on October 10 and 11. The event will be held in English.
This year, the focus is on EUPOS, a ground-based European GNSS augmentation system, and on the regional geodetic reference frames and systems, ground-based GNSS infrastructures and technical developments in the field of DGNSS.
By Inside GNSSSIRGAS 2011, the annual working meeting of the organization in charge of the geocentric reference system for the Americas, will be held in Heredia, Costa Rica from August 8 to 10.
It will take place in Clodomiro Picado Twight auditorium at the Omar Dengo campus of the National University of Costa Rica.
By Inside GNSSNavtechGPS will offer its 2011 east coast GNSS technical seminars at the Doubletree Hotel in Annapolis, Maryland from Monday, July 11 through Friday, July 15.
Over 25 years, NavtechGPS has organized basic and advanced GNSS seminars for engineers and technical professionals all over the United States and has provided GPS/GNSS applications solutions for military and research customers, with product choices from more than 30 manufacturers.
By Inside GNSSICG-6, the sixth meeting of the UN’s Sixth Meeting of the International Committee on GNSS, will take place in Tokyo from September 5-9.
By Inside GNSSThe 2011 International Summer School on GNSS will take place July 20 to July 30 in Berchtesgaden, Germany at the GATE facility (Galileo Test and Development Environment).
This year’s theme is Towards a Mutli-Constellation Multi-Frequency GNSS and SBAS.
You may still register online for the waiting list. (Link here for the summer school program. )
By Inside GNSSThe Swiss Federal Institute of Technology (ETH) sponsors this conference and exhibition on UAVs and geomatics at Campus Science City (Hoenggerberg) in Zurich, Switzerland from September 14 through 16, 2011.
UAV-g 2011 will bring together experts in photogrammetry, surveying, robotics, computer vision, artificial intelligence and aerospace engineering.
Researchers, developers, service and systems providers and users are invited to exhibit and demonstrate their UAV systems in geomatics at at the Birrfeld airfield on Thursday, September 15.
By Inside GNSSCooperative vehicle safety applications should preferably have two-meter horizontal accuracy and six-meter vertical accuracy, all with a 95-percent availability. The solution must be developed to incorporate lower-cost sensor options, specifically, lower-cost inertial measurement units that can be generally characterized by the gyro drift of 100 degrees per hour and an accelerometer bias force of twice its mass times gravity (two milligals).
