Septentrio delivers machine control receivers to world’s largest iron ore mine

Vale's S11D mine at Carajás.

Septentrio Americas has delivered over 40 GNSS machine control receivers for deployment at the Vale S11D Iron Project in Carajás, Brazil, also the world’s largest iron ore project. The Septentrio receivers, which include the new AsteRx-U products, will be installed on mining equipment from three different machine suppliers.

Vale’s new S11D mine site will produce more than 90 million tons of iron ore annually when it becomes operational later this year. A highly automated truckless transport system is being implemented at the project site, leveraging technology from Belgian company Septentrio and other leading mining companies. The transport system is expected to substantially reduce fuel consumption and emissions while also saving water.

Septentrio GNSS receivers and antennas will be deployed across a range of machines to provide highly accurate and reliable position and orientation. Feature highlights of the AsteRx-U receiver family include built-in jamming detection and countermeasures; multi-path rejection and fast acquisition; 500-plus channels to track all available constellations (GPS, GLONASS, Galileo, Beidou, IRNSS and QZSS); and a built-in L-band receiver for PPP corrections as well as centimetre-level RTK positioning accuracy.

Proprietary Septentrio algorithms have been incorporated in the AsteRx-U receiver family including LOCK+ technology to maintain tracking during heavy machine vibration, and IONO+ technology to ensure position accuracy even in regions of elevated ionospheric activity. The receiver is configurable from any device with a web browser, and includes advanced capabilities such as a built-in spectrum analyser.

The Vale S11D machine control project is being managed from Septentrio Americas in Torrance, California.

Observing that Septentrio has been a leader in multi-constellation and multi-frequency machine control GNSS receivers for the past decade, Septentrio Americas Vice President Neil Vancans said the selection of AsteRx-U receivers for Vale’s S11D project is a strong validation of the product’s rugged design and high performance in challenging environmental conditions.
