Product Name: Naval Navigation System
Product Description
A
typical Naval Navigation System (NNS) is a navigation data calculation and
distribution system.The NNS optimizes data distribution from available sources,
featuring redundancy, flexibility and adaptability for future requirements.
Astronautics naval navigation systems are used in the Israeli Navy, U.S. Coast
Guard and more.
NAVIGATION SYSTEM :
The Ship/Submarine integrated and Distributed Navigation System is a modern,
advanced, low cost, off the shelf navigation package for marine surface and
subsurface ship application.
The system collects data measured by the various navigation sensors (such as:
Ring laser gyro with embedded GPS, Log, Echo sounder and Meteorological unit),
processes the data and distributes it to the users through the vessel in several
formats, including digital, Synchro and discrete information. The system can be
expanded to include the Auto pilot and ECDIS system.
Astronautics\' products as part of the system:
INS:
Three-axis Monolithic Ring Laser Gyro with embedded GPS
Re Transmission unit: Drives isolated high power Synchro and digital navigation
information to the \'Users\'.
CDU: High brightness Robust 6”x8” LCD controlling the system and presenting the
data (locally as a repeater).
System Description:
The Astronautics Navigation System (NAVSYS) family of products is derived from
the successful Israeli Navy latest SAAR 5 Frigate and the Dolphin type
Submarine.
The NAVSYS provides high performance, cost effective solution for generation and
distribution of high accuracy geographic position information, with or without
GPS, and precise attitude and heading data needed for weapon and platform
stabilization.
A typical system is comprised of two Ringlaser Gyro INS\'s, ReTranmission Unit (RTU),
GPS, EM speed Log, Echo Sounder (depth sensor) and a Meteorological Unit. These
sensors are selected to provide redundancy of sources of navigation data and are
used to assure the highest accuracy of each navigation parameter.
The NAVSYS has been tested and verified to meet all military specification
environmental requirements.
The NAVSYS is proposed as a total package. This includes selection of the most
effective available components, complete software configuration, technical
supervision during installation and operator training to ensure the
effectiveness of the system.(STW, HAT, SAT, ...)
The NAVSYS can be used as an upgrade to existing ships or for newly built ships.
Customizing the system by subsystem substitution or addition can readily be
accomplished.
It is easy to adapt various types of input sensors such as GPS , Speed
Log, Depth sensors, Metro units and INS\'s by means of software change.
Deliver Accurate, Zero Latency, Roll Pitch And Heading Synchro Information
Number of synchro channels is unlimited (baseline configuration :96 users)
The NAVSYS is designed to support a large variety of synchro types/scaling
(designed for low cost, software only adaptation to specific customer
requirements)
Synchro loads are driven from individually buffered power amps with
short circuit protection. Providing isolation between loads, operational safety,
high survivability and BIT capability not achievable with a synchro bus.
Synchro Distribution Units can be located near the synchro users toimprove
survivability, to provide redundancy and to save system cable weight.
Deliver optimal RS422 navigation data (Position, Velocity, Depth, Wind etc.)
Number RS422 channels is practically unlimited (baseline configuration supports
72 50 Hz broadcast channels, 24 2 Hz broadcast channels and 24 uart configurable
channels)
Redundancy of critical components combined with RTU\'s LCF© and ODF© algorithms
(Latency Canceling Filter & Optimal Data Fusion) to assure availability as well
as the highest accuracy of each navigation parameter.
Automatic Switching Between INSs (manual selection is possible)
Extensive Failure Detection ,Isolation & Repair on board, without external
Tester.
User Friendly, Menu driven Operation and Control.
System in Astronautics family of Navigation:
Watertight INS Doppler velocity log- (SEADeViL)
The
Seaborne Navigation System/Doppler Velocity Log (SEADeViL) is the latest
addition to Astronautics\' family of inertial quality pointing, stabilization,
survey, and navigation devices for maritime applications. The SEADeViL modular
architecture provides maximum flexibility, offering selectable performance and
future upgradeability. A sophisticated Kalman filter allows the combining of INS
data with the embedded GPS and/or Sonar/Doppler. Typical applications for the
SEADeViL are patrol boats, surface and subsurface vessels, remotely operated
vehicles, and research/survey vehicles.
