Maritime projects: two new orders entrusted to Cadden
Nantes, April the 15th, 2006. Cadden, a company specialised in electronic measurement systems for positioning, orientation and navigation, announces the delivery of several GPS receivers ordered by the Harbour Authorities of Le Havre and the GIE Dragages & Ports (a dredging company) for applications in bathymetry and dredging.
New “Backup” Mode: an option retained by the two sponsors
The equipment delivered includes a GPS reference station and five dual frequency GPS receivers. They were ordered with the “backup” option, which has proven a decisive factor in the choice of equipment. This new operating mode, unique in the market, is available on Thales Navigation’s Aquarius receivers since July 2005.
Relying on redundancy, the backup mode enables two simultaneous calculations of a single GPS position, from two different reference stations. In cases where the signal is disrupted, the toggling from one measurement to the other is done immediately and clearly for the user, while maintaining the same level of accuracy.
Different Fields of Operation
Thanks to this functionality, the Harbour Authorities of Le Havre anticipate significant savings in operating time over a bathymetry area located at the foot of a cliff. Once the UHF relay —situated on the Pont de Normandie— is replaced by the reference station, the new receiver equipping the launch will be able to receive GPS corrections without any interruption.
