Product Name: Naval Navigation System

Product Description

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.
