Beidou Satnav System Operational

On 27th December 2011, Chinese officials confirmed that the country's Beidou satellite navigation system was operational, albeit mainly in China, and on track to meet the goal of offering free, global coverage by 2020. At a press conference, the China Aerospace Science and Technology Corporation said that Beidou is providing location data and SMS messaging using a network of ten satellites currently in orbit, and another six launches are planned for 2012.     Once fully operational, they should cover most of the Asia/Pacific region, and will form the backbone of a global system of over 30 satellites that should...

CenterPoint RTX Post-processing Service Adds Galileo and BeiDou MEO Satellite Preview

Trimble, USA, released a preview version of its CenterPoint RTX post-processing service at ION GNSS 2013, enabling GNSS observations using available Galileo and BeiDou Middle Earth Orbit (MEO) satellites. Powered by Trimble RTX technology, the free CenterPoint RTX post-processing service provides better than centimetre-level positions. The existing CenterPoint RTX post-processing site uses data from the GPS, GLONASS, and QZSS satellite systems. Through a link accessible from the post-processing website, users can enter a preview site and derive positions that also use data from available open service Galileo and BeiDou MEO satellites. With the addition of Galileo and BeiDou MEO support,... (read more)

Fugro Launches G4 Satellite Positioning Augmentation Service

Fugro has further extended its technology leadership in the field of GNSS augmentation systems for offshore positioning applications with the launch of its G4 service. The satellite correction service is the first to take advantage of all four global navigation satellite systems (GNSS): GPS, GLONASS, BeiDou and Galileo. GNSS augmentation services improve position accuracy compared with unaided GNSS receivers. By using all available GNSS satellites, Fugro’s G4 service is designed to improve availability and reliability of offshore positioning and will thus enhance the safety and productivity of a wide range of survey and other activities offshore. G4 represents an advancement... (read more)

Fugro’s G4 Satellite Correction Service Optimises Latest Galileo Launch

Users of Fugro’s G4 satellite correction service will be among the first in the world to benefit from Galileo’s ‘initial services’ launch. This week, Fugro takes full advantage of Galileo’s operational milestone. The launch of Europe’s satellite navigation system’s new ‘initial services’ capability means that all Fugro’s G4 satellite correction service users will instantly benefit from much greater accuracy and reliability. Fugro’s G4 service, launched in February 2015, was the first to utilise all available global navigation satellite systems (GNSS) – GPS, GLONASS and BeiDou. From its launch date the service was prepared for Galileo and Fugro’s G4 users now... (read more)

GNSS Receiver for Time and Frequency Transfer Applications

Septentrio has launched a GNSS receiver for dedicated time and frequency transfer applications: the PolaRx5TR. The PolaRx5TR has 544 hardware channels and supports all major satellite constellations including GPS, GLONASS, Galileo, BeiDou, QZSS and IRNSS. A calibration circuit is incorporated into the PolaRx5TR to measure and compensate for the internal delay. This feature removes the need for calibration using external equipment and ensures measurement latching is always accurately synchronised with the PPS input. Septentrio’s PolaRx5TR is compliant with the format CGGTTS version V2E of Consultative Committee for Time and Frequency (CCTF) recommendations. Also included as standard is Septentrio’s Advanced Interference... (read more)
