Northrop Grumman Wins Phase II Contract to Upgrade Inertial
Navigation Systems for Brazilian Navy
( text in portuguese Link)
CHARLOTTESVILLE,
Va., Oct. 31, 2006 -- Northrop Grumman Corporation has been
awarded a contract from the Brazilian Navy for the second
phase of a multi-year retrofit acquisition program to upgrade
the primary navigation systems on its combat ships.
The
ship inertial navigation systems (SINSs) will be supplied
by Northrop Grumman's Sperry Marine business unit.
Sperry Marine will supply eight new-generation MK39 ring-laser
gyro (RLG) systems plus supporting interfaces, accessories
and spares. They will replace the current MK29 military
gyrocompass systems on the ships. The new systems will provide
high-accuracy position data and precise attitude, velocity
and heading inputs for the ships' navigation and fire-control
systems.
"Sperry Marine's MK39 provides the Brazilian Navy with
the best-value solution for their SINS requirements, giving
them a rugged state-of-the-art primary navigation system
for their combat vessels," said J. Nolasco DaCunha,
director of Sperry Marine Systems. "The Phase II SINS
program builds on Sperry Marine's longstanding relationship
with the Brazilian Navy, dating back more than 30 years."
Sperry Marine is a world leader in RLG technology, having
supplied more than 80 percent of the RLG SINS systems at
sea today. The MK39 SINS has been specified by more than
28 international navies for a variety of platforms.
Sperry Marine, with worldwide headquarters in Charlottesville,
Va., and major engineering and support offices in New Malden,
United Kingdom and Hamburg, Germany, is part of Northrop
Grumman's Electronic Systems sector. Sperry Marine provides
smart navigation and ship control solutions for the international
marine industry with customer service and support through
offices in 16 countries, sales representatives in 47 countries
and authorized service depots in more than 250 locations
worldwide.

The MK 39 Ring Laser Gyro Navigator Story
Elmer
Sperry patented the first gyrocompass designed expressly
for the marine environment in 1910. This "spinning
wheel" gyro was a significant improvement over the
traditional magnetic compass of the day and changed the
course of naval history. The first Sperry gyrocompass was
tested at-sea aboard the USS Delaware in 1911 and established
Sperry as a world leader in the manufacture of military
gyrocompasses for the next 80 years.
Sperry
Marine introduced Ring Laser Gyro (RLG) technology to the
world of ships and submarines in 1990 and in just a few
short years the RLG replaced the "spinning wheel"
for all precision navigation applications worldwide. Today
the Sperry Marine MK49 is the standard RLG Ship's Inertial
Navigation system for NATO ships and submarines, the AN/WSN-7
RLGN is the next generation navigator for all U.S. Navy
submarines, aircraft carriers and other surface ships, and
the MK39 RLG system has been selected by more than two dozen
international navies, the U.S. Military Sealift Command,
and the U.S. Coast Guard for application to many different
surface ship platforms. More than 80% of all RLG navigation
systems operational in navies today carry the Sperry Marine
name.
Sperry
Marine is now producing our third generation Ring Laser
Gyro Inertial Navigation System - the MK39 MOD 3A. The MK39
MOD 3A provides both high accuracy geographic position information,
with or without GPS, and precise attitude and heading data
needed for fire control stabilization and weapons initialization.
The MK39 MOD 3A occupies 36% less deck space than our previous
models, utilizes enhanced Digital Ring Laser Gyro technology,
and is certified for submarine applications due to its extremely
low noise signature.
The
MK39 MOD 3A, like all previous Sperry Marine gyrocompass
and navigation systems, is designed and built with the experience
and integrity that is only found in a company with over
90 years of dedication to the marine ship and submarine
market. The MK39 MOD 3A stands ready to take your navy well
into the next millennium, today.
