  6. Products & technologies • IXSEA is a world leader in three technologies: • Fiber Optic Gyroscopes (FOG) • OCTANS gyrocompass & motion sensor • PHINS Inertial Navigation System • Underwater Acoustics • Acoustic Releases • POSIDONIA USBL • Magnetic sensors • MAGIS

  7. PRODUCTS • PHINS • a navigation system (INS) providing data on the attitude (true heading, roll, pitch) and position (latitude, longitude, altitude) of any mobile object. • OCTANS • a strap-down IMU that contains three fiber optic gyros in the 0.05°/hour class, three milli-g acelerometers, and a real-time DSP computer. • POSIDONIA • USBL Acoustic Positioning System using an innovative combination of Chirp & FM modulation techniques. • GAPS • a unique Global Acoustic Positioning System based on iXSea’s mastery of INS and acoustic Chirp modulation techniques.

  9. PHINS: Solution Positioning

  10. PHINS: Turnkey for Marine Applications • Marine Positioning System • PHINS is an Inertial Navigation System specially designed to provide surface vessels with: • Position • Heading • Heave • Speed • Attitude • An ideal tool for survey and positioning • A cost-effective concept • Open to multiple sensors

  11. PHINS is not only the lightest and most compact Inertial Navigation System designed for Marine vehicles but also the most effective system. Multibeam Hydrographic Survey Dynamic Positioning • Consuming little power and ready to integrate, it is the ideal solution for multibeam hydrographic surveys and Dynamic Positioning systems.

  15. OCTANS

  16. OCTANS: Easy Set-Up & Configuration • OCTANS configuration software allows an individual setting of each port and the simultaneous use of up to 5 inputs and 7 outputs. • Serial I/O • • Protocol • Industry standards, • NMEA 0183,binary • • Electrical Level • RS232 or RS422 • • Baud Rates • 600 Bauds to 115 K Bauds • • Bits • Number of stop bits/parity • Analog I/O • Scale factors • Pulses I/O • Scale factors • Output Frequency • 0.001 Hz up to 100 Hz • Internal Update Rate • 300 Hz • Heave Filtering Self Adaptive

  17. OCTANS Operational Assets • No Heave Build-Up:heave stays stable during turns without the aid of external sensors • Easy Integration:OCTANS interfaces all multibeam • and single beam echo sounders, ADCPs, and survey packages OCTANS emulates all existing motion sensors and gyrocompasses • Monitoring of up to 3 points (lever arms / angular offsets) • No external control unit

  47. Requirement for a Subsea Release Acoustic Release Introduction • To RELEASE a load • By REMOTE CONTROL(usually the surface) • When we want(Timers actuate at a fixed time…) • Nothing visible on the surface • No obstruction to shipping • No surface float to drag the mooring sideways • No diver required • Re-usable… again and again

  48. An ACOUSTIC RELEASE SYSTEM is … • Remote control surface TELECOMMAND unit sending commands through the water • A subsea receiver unit with aRELEASE HOOK
