Autonomous Real-time PVT Calculation from Galileo IOV Satellites

Septentrio, Belgium, has announced that it has obtained, based on live ICD compliant Galileo messages from the four Galileo IOV satellites, a first autonomous real-time Galileo PVT calculation. The stand-alone position was calculated from in-orbit navigation messages using a standard PolaRx4 GNSS receiver equipped with commercially released firmware. This achievement follows shortly after the announcement of a first GPS+Glonass+BeiDou PVT less than two weeks after the BeiDou ICD v1.0 publication in December 2012. Peter Grognard, Septentrio’s founder and CEO, said that he is delighted that Septentrio receivers are amongst the first to witness the readiness of the Galileo navigation message... (read more)

Hemisphere GNSS Introduces Eclipse P306 and P307 at Intergeo

Hemisphere GNSS will introduce the Eclipse P306 and P307, the latest models in the Eclipse series, at Intergeo. The Eclipse P306 and P307 track multi-frequency GPS, GLONASS, and BeiDou satellite signals and are Galileo and QZSS-ready. By tracking more signals, RTK positioning performance improves, especially in challenging environments. The Eclipse P306 and P307 are the first products to utilise the company’s new SX4 ASIC. Capable of simultaneously tracking code and phase signals on 89 satellites, SX4 boasts 372 channels and can be configured to address several diverse applications through software. Smaller than a business card, the Eclipse P306 upgrades existing... (read more)

Tallysman Optimises GNSS Antennas with Accutenna Technology

Canada-based company Tallysman has announced that its range of antennas featuring proprietary Accutenna technology is optimised for today’s multi-constellation satellite systems, including the Galileo system, BeiDou, GPS, GLONASS and IRNSS. Additional satellites were launched by the ESA (Galileo 7 and 8) the US (GPS IIF-9) and India (IRNSS-1D) during March 2015, and it is believed that China has also successfully launched its new-generation BeiDou-3 M1. The expanding number of satellites will benefit many applications, from next-generation in-car navigation systems to coastguard search & rescue and precision agriculture. Tallysman describes their compact GNSS antenna range with Accutenna technology as future-proof. GNSS... (read more)

Core Wall Control Survey in Kuwait

Using BeiDou for Tall Building Construction in Kuwait
Tall towers can bend and sway due to wind, cranes and other loads. Ideally, such movements should be around the main axis designed so that, in the absence of loads, the tower stands exactly vertical. However, raft settlement, concrete shortening and construction tolerances cause deviations. The core wall control survey method was adopted to drive the new headquarters of the National Bank of Kuwait – a 300m-tall building – in the vertical direction with millimetre accuracy. The method uses GNSS CORS technology. This is the first time that signals from the available BeiDou GNSS satellites have been used to assist... (read more)

Precise Point Positioning from Combined GNSS

Fugro Marinestar G4+ PPP-RTK Developments
Currently there are four global navigation satellite systems (GNSSs) available: GPS, Glonass, BeiDou and Galileo. The satellites of these systems are used for positioning, and the accuracy is greatly improved if precise satellite orbit, clock and uncalibrated phase delay (UPD) corrections are available when using the precise point positioning (PPP) technique. Fugro operates a worldwide network of reference stations capable of tracking GPS, Glonass, BeiDou and Galileo systems. This network is used to calculate precise satellite orbit and clock corrections of all four constellations in real time for maritime applications. The corrections are broadcast to users by eight geostationary L-band... (read more)
