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
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.
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
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.

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
An ACOUSTIC RELEASE SYSTEM is … • Remote control surface TELECOMMAND unit sending commands through the water • A subsea receiver unit with aRELEASE HOOK
Telecommand TT301B • Telecommand TT301B is compatible with the whole product range. • NEWTT801is also compatible with the whole product range.
