A ground system aimed at enhancing the navigation precision of BeiDou Navigation Satellite System (BDS) was approved in central China’s Hubei Province. The BeiDou Ground Base Enhancement System (BGBES), a network consisting of 30 ground base stations, an operating system and a precision positioning system
PetroVietnam University (PVU) has joined the Intergraph® Education Grant Program, selecting SmartMarine® Enterprise solutions for its curriculum to support Vietnam’s offshore oil and gas industry. PVU is located in the offshore oil and gas hub of southern Vietnam, and was established to focus on the development of the country’s oil and gas industry. www.pvu.edu.vn
Septentrio has announced that they have obtained, based on live ICD compliant Galileo messages from the four Galileo IOV satellites, a fi rst autonomous realtime Galileo PVT calculation. The standalone position was calculated from in-orbit navigation messages using a standard PolaRx4 GNSS receiver equipped with commercially released fi rmware. www.septentrio.com.

NovAtel Inc., has added a new commercially exportable MEMS IMU (micro electromechanical inertial measurement unit) to its line of SPAN GNSS/INS products. It is supplied by Analog Devices (Norwood, Massachusetts) and is exclusive to NovAtel. It can be paired with an OEM6 receiver card to provide continuously available position, velocity, and attitude (roll, pitch, yaw) in a small, single-unit form factor.
Philipp Ronnenberg, a masters student in design interactions at the Royal College of Art in London, recently showed off the first prototype sensors for his alternate “Open Positioning System,” which are designed to pick up regular seismic waves given off by large machinery in nearby power plants and factories. Once a sensor detects at least three different nearby seismic wave sources, Ronnenberg theorizes it should be able to determine its location. So far, he’s built a prototype sensor using the Arduino open source hardware microcontroller, which he says “can detect and collect different frequencies.
