Page 4: Introduction
In a noisy environment With strong immunity to reflection and reverberation Since its first introduction on the market in the late 90’s POSIDONIA II has constantly been maintained to operational conditions, with a number of worldwide applications for deep sea vehicle/long range tracking up to deepest seas. - Page 5 GPS input is used to convert into an absolute geographical position of the target. Up to 8 transponders can be tracked with POSIDONIA II within the same interrogation cycle. This number of transponders, acoustically managed in a single operation without mechanical scanning, implies the need for coding of the signals.

Page 6: System Standard Configuration
1.3. System standard configuration Unless otherwise specified and agreed at time of project discussion a standard POSIDONIA II USBL positioning system comprises the following sub-assemblies: Main Equipment One (1) off acoustic array (portable version equipped with preamplifiers, shipped in wooden box) One (1) off main interconnect cable (50 m long standard supply) ... -
Page 7: Detailed Item Description
The whole electronics is now integrated in a compact 19’’ rackmount topside, integrating all required hardware and software to smoothly interface to external sensors (antenna, HARS, GPS, data output, synchro, etc) and computing power for calculating the final position of the tracked subsea vehicles. www.ixblue.com TD_POSIDONIA II_2016_08_b Page 7 of 29... -

(deployed on sea bed) during initial setting to work, and every time the acoustic array is moved from its current installation. Although POSIDONIA II is able to interrogate releasable transponder and send command codes an iXBlue TT801 portable deckset telecommand unit is recommended for separate and easy configuration and preparation / recovery of mooring lines. -

500 kg to 300 tons SWL (Safe Working Load) 1.4.4. POSIDONIA II MMI (Man Machine Interface software) Most components in the subsea positioning solution (PHINS, POSIDONIA II, RAMSES) are delivered with iXBlue new WEB-based graphic user interface which is progressively installed to the full range of products, providing a common look-and-feel to all products. -
Page 10: Display Software
1.4.5. Display software POSIDONIA II system provides data telegrams with each transponder’s position for use with any third party navigation package, with various communication protocols. Several outputs are available (Ethernet and RS232 format) which allow data distribution to different peripherals. -

Page 13: Posidonia Ii Electronics Installation
No specific knowledge is required for this part and the operation can be achieved in a very short time. POSIDONIA II already interfaces to most of the heading and motion sensors and GPS available on the market with a large library of communication protocols. (NMEA0183... -
Page 14: Posidonia Ii System Performance & Specifications
(ambient noise level, propagation conditions) are the most sensitive parameters. Although some existing solutions are available to improve performances in case of difficult acoustic environment (see next chapter), the standard POSIDONIA II configuration performances are defined with the following conditions: Positioning accuracy 0.2% x slant range... -
Page 15: Use High Accuracy Heading And Motion Sensor
An accuracy of 0,15 deg or better for heading and 0.05deg for Pitch & Roll is recommended in order to reach nominal performances of the POSIDONIA II USBL system. iXBlue manufactures a high grade Fiberoptic Gyroscope and Motion sensor, OCTANS, which is a perfect match with POSIDONIA II requirements: heading accuracy : 0.1deg (x secant latitude) -
Page 16: Use Pressure Sensor
X/Y data and correct it. POSIDONIA II can use either optional pressure sensor installed in the iXBlue transponder (optional, data retrieved through umbilical or through the acoustic channel) or third party pressure sensor if available on the tracked vehicle. -
Page 17: Use Posidonia Ii Coupled To Phins + Dvl Subsea
The mathematical tool used to perform this data fusion is a Kalman filter – it is embedded into the PHINS (INS). Using data fusion between PHINS, POSIDONIA II and other optional sensors benefits: Advantages of POSIDONIA II acoustic systems: the positions remains stable and accurate on the long term;... - Page 18 Positioning output with POSIDONIA II alone (no INS coupling and data fusion) Positioning output with data fusion with INS and other sensors: Smooth, high data rate Noise filtered Robust to GPS and ACOUSTIC outages Higher accuracy and range ii/ example: GAPS + PHINS + DVL Real field data, collected in La Ciotat bay - France, using such an integrated system.
