BeiDou

Prof. Jingnan Liu, Chinese Academy of Engineering

Since announcing plans in late 2006 to build its own GNSS system — BeiDou-2 (BDS), China proceeded quickly to establish a fully operational regional system late last year with a clear plan to complete a global system by 2020.

Beginning with its first launch in April 2007, BDS has put 16 satellites in orbit, some in dual launches, with 14 BeiDou space vehicles currently transmitting healthy signals: 5 in geostationary orbits (GEO), 5 in inclined geosynchronous orbits (IGSO), and 4 middle Earth orbit (MEO) spacecraft.

Galileo Conversation: Regulation, Budget, Markets, and International Relations

Paul Flament is head of the European Commission’s Satellite Navigation Unit. His primary job, essentially, is to manage the Galileo program of the European Union (EU). With four operational satellites now in orbit and an ambitious schedule to set in place a constellation of 26 by 2015, Flament sat down with Inside GNSS to talk about a number of pressing issues that could affect the future of Galileo.

Flament first addressed the EU GNSS Regulation, the much-anticipated document that sets out just who will do what in the future Galileo program.

Topcon Launches OEM Precise Heading Product

Topcon Positioning Systems (TPS) has announced the MR-1 Heading System, an OEM GNSS solution for high-performance positioning and heading applications on moving platforms.

Using the MR-1 receiver and Topcon’s patented MG-A8 antenna, the system provides “centimeter-accurate RTK positioning and better than 1/10 of a degree heading accuracy in challenging environments,” said Doug Langen, TPS GNSS product manager.

NovAtel Launches New Series of SPAN IMUs

NovAtel Inc. has announced its new SPAN-IGM series of micro-electromechanical system (MEMS) inertial sensor products, including the IMU-IGM-A1 MEMS enclosure and the SPAN-IGM-A1 GNSS/INS enclosure.

The IMU-IGM-A1 is a small , rugged enclosure that houses a MEMS inertial sensor, which can be configured from the factory as an integrated GNSS + Inertial Navigation System (INS) or as a standalone IMU sensor for pairing with a customer’s existing SPAN-enabled OEM6 receiver. Its dimensions are 152 (length) x137 (width/diameter) X 51 (height) millimeters.

RedBlade

Anyone who has gone to college is probably familiar with the idea of a capstone course. A final hurdle to clear in receiving a degree, students take such a course to demonstrate their practical knowledge by pulling together all of the main concepts taught throughout the program of study.

From Fledgling to Flight

Allure Shadow (top), structural clearances (bottom)

The Boeing Company initiated the Unmanned Little Bird (ULB) program in the fall of 2003 to create a developmental platform for an optionally manned, vertical takeoff and landing (VTOL) unmanned aerial vehicle (UAV). Initial flight test activity employed a modified MD530FF helicopter, with the first flight taking place on September 8, 2004. Six weeks later the program achieved a fully autonomous multiple waypoint demonstration flight from takeoff through landing.

East Meets West: Hemisphere GNSS’s New Era

Xinping Guo, president and chairman, Beijing UniStrong

Although not on the scale or at the strategic level of China National Offshore Oil Corporation’s takeover of Canada’s Nexen Inc., the recent acquisition of the Precise Products business of Hemisphere GPS by Beijing UniStrong Science & Technology Co. Ltd. marks a notable achievement in the GNSS world — the acquisition of a North American manufacturer with core GNSS receiver intellectual property by a Chinese enterprise.
