Septentrio GNSS technology guarantees DEME’s operations in areas of interference

February 13, 2017 – Septentrio GNSS technology continues to provide solutions for challenging situations.

Case in point? The Belgian dredging, environmental and engineering group DEME. They rely on the accuracy and reliability of the AsteRx family of precise GNSS positioning solutions from Septentrio.

DEME is using Septentrio’s AsteRx GNSS receivers to obtain centimeter-level accuracy for all their dredging and marine construction operations worldwide.

These receivers are designed to operate in difficult conditions. From ice-covered Arctic ports to the tropical climates of Southeast Asia; whether dredging a few meters from the coast line to constructing wind turbines kilometers out at sea.

Septentrio GNSS technology, a case study

DEME began using Septentrio’s solutions over 10 years ago. While dredging in the Belgian town of Oostende, DEME couldn’t obtain a reliable RTK position from their GNSS equipment. The problem? Interfering radio signals from a local radio tower. Septentrio worked with DEME to identify the source of the interference. Once the problem was discovered they modified a standard RTK receiver with special firmware to address the jamming problem.

This case, along with others faced by Septentrio’s customers in the field, began development of a dedicated interference mitigation technology called AIM+ which is now standard in Septentrio’s GNSS solutions.

History of success

Septentrio’s AsteRx GNSS receivers are deployed on DEME’s ships around the world. They have been vital to DEME for the success of projects such as the creation of Gateway Port in London, UK; the construction of Deurganckdock, Antwerp, Belgium; the
Pearl Qatar City; Thornton Bank Offshore Windfarm, Belgium, extension of the Suez Canal, Egypt and many more.

“’Creating land for the future’ is the slogan here at DEME and this is thanks in part to the accuracy and robustness of the solutions offered by Septentrio” stated Lorentz Lievens, Head of Survey Department.

“Jamming is a concern which DEME has seen more and more all over the world. Septentrio’s receivers are unique in that they continue to provide an accurate solution even in areas of high radio and ionospheric interference allowing DEME to deliver projects on time and on budget,” continued Lievens.

Septentrio’s precise positioning solutions will remain vital for DEME to deliver quality and cost-effective operations around the world for many years to come.”

About Septentrio

Septentrio designs, manufactures and sells high-precision multi-frequency multi-constellation GPS/GNSS equipment, which is used in demanding applications in a variety of industries such as marine, construction, agriculture, survey and mapping, geographic information systems (GIS), and unmanned aerial vehicles (UAVs) as well as other industries. Their receivers deliver consistently accurate GNSS positions scalable to centimetre-level, and perform solidly even under heavy scintillation or jamming. Receivers are available as OEM boards, housed receivers and smart antennas.
