Fugro has been awarded a contract by subsea contractor DeepOcean for the provision of precise satellite positioning for its fleet.

The contract is valid for three years and also includes the new vessels in DeepOcean’s expanding fleet. The DeepOcean fleet will be equipped with hardware and software developed by Fugro, providing independent positioning solutions on each vessel.

Under the contract, Fugro will supply DeepOcean with three independent decimeter-level satellite navigation systems. Also part of the contract delivery are Fugro’s Starfix.G2+ system, which has a 3D accuracy approaching that of GNSS RTK systems, and Fugro’s Starfix.G4 satellite correction service.

Starfix.G2 is a GPS and GLONASS positioning system based on orbit and clock corrections generated from Fugro’s own expanded network of dual system reference stations. Starfix.G2 is a precise point positioning (PPP) technology, which distinguishes itself from the traditional differential approach as satellite errors are not lumped together but estimated per source, per satellite. The GPS/GLONASS orbit and clock corrections are computed separately, free of ionospheric and tropospheric effects.

Starfix.G4 is a GPS, GLONASS, Galileo and BeiDou positioning system based on orbit and clock corrections generated from Fugro’s network of reference stations. Like Starfix.G2, Starfix.G4 also uses PPP technology. The GPS/GLONASS/Galileo/BeiDou orbit and clock corrections are computed separately, free of ionospheric and tropospheric effects.

DeepOcean is an integrated provider of services and technologies for the subsea industry, including offshore services for oil and gas, offshore renewables and electrical power transmission industries, with offices in Norway, UK, Holland, Brazil, Mexico and Singapore.
