BlueNaute navigation system chosen by US Coast Guard for the Juniper
WLB class ships
After issuing an international request for proposals (RFP), the US Coast
Guard has chosen Sagem (Safran)'s new attitude and heading reference
system, BlueNaute®, to modernize a dozen of its ocean-going ships.
About a dozen Juniper WLB class ships will be fitted with the BlueNaute
Coast Guard Cutter Walnut (WLB-205), a seagoing WLB Juniper class buoy
tender based in Honolulu. USCG photo by PA1 John Gaffney. The WLB Juniper
class is a 2,000 tons ocean-going ship, specialized in the laying of
navigation buoys, the fight against pollution and search missions at
sea. The US Coast Guard deploys 16 ships of this type.
BlueNaute reference system is based on hemispherical resonator gyros
(HRG), a proprietary Sagem technology that gives the BlueNaute very
high reliability, coupled with extremely precise measurements. A disruptive
navigation technology, the BlueNaute's inertial core offers a competitive
advantage in terms of total cost of ownership and performance, versus
the previous generation of inertial technologies, especially fiber-optic
and mechanical models.
With mean time between failures (MTBF) exceeding 100,000 hours, Sagem's
BlueNaute system addresses evolving maritime navigation requirements.
Its unexcelled performance qualities make it a perfect match for scientific
missions, at-sea searches, offshore operations and coast guard or police
BlueNaute's ergonomic design, performance and longevity were all decisive
factors in the system's selection by the US Coast Guard for its WLB
