Project WiMUST, Achievements



Sines17

WiMUST'17 (Port of Sines, 17-21 July 2017)

is a project wide sea trial with the collaboration of all partners. It took place in a protected inner bay of the Sines Port and will encompass all aspects of vehicle navigation, guidance and control, underwater communications and seismic acoustic signal recording and analysis.

People involved from UALg: P. Felisberto, P.J. Santos, S.M. Jesus, C. Soares, A. Mantouka and F. Zabel.

Sines Port

WiMUST'16 test, (Sines, 26-28 November 2016)

(upcoming) this is a project wide sea trial with the collaboration of all partners. It will take place in a protected inner bay of the Sines Port and will encompass all aspects of vehicle navigation, guidance and control, underwater communications and seismic acoustic signal recording and analysis.


testing the DTU at Alfeite tank

Anechoic tank test - Base Naval (Alfeite, 7-8 November 2016)

(upcoming) this test aims at calibrating the DAVS receiver and determining its approximate radiation diagram in an anechoic controlled environment tank.
Facilities are provided by the Base Naval do Alfeite from the Portuguese Navy and CIMAV .


red Medusa with DAVS

DAVS test - Expo Marina (Lisboa, 26 September 2016)

Dynamic tests with the DAVS mounted on an AUV were performed at the Expo Marina in Lisbon at the end of September 2016, thanks to the collaboration and availability of the IST-ID team that provided the AUV. See picture at left showing the DAVS strapped on top of the red Medusa. Note that the Medusa is shown upside down in this picture, so after deployment DAVS will imerged below the lower container of the AUV at approximately 0.5m depth.


DAVS signals

DAVS static test (Faro beach, 25 August 2016)

the first field test of the DAVS took place at the pontoon of the Nautical club of Faro beach. Various receiver orientations and source - receiver distances were tested. Signals for various orientations are shown in the figure at left.


DAVS

DAVS development (SiPLAB, UAlg, Jan-August 2016)

the Dual Accelerometer Vector Sensor was developed at SiPLAB for the purpose of the WiMUST project in the first semester of 2016. It encompassed CAD design and modelling, 3D printing and CNC for the different mechanical parts, molds and containers. Printed circuit board desing and development for the various electronic components of the recorder as well as the development and testing of the respective embedded software. Finally it involved polyurethane molding and testing of the various sensors and receivers. Pictures below detail some of the various steps of this quite long prototype process.


deploying Medusa

Communication test - Expo Marina
(Lisboa, May 10, 2016)


This test aimed at determining the acoustic sound pressure radiated by acoustic modems and Medusa vehicles' motors in normal WiMUST type operation, as received on the first towed array sensor (about 1m from the stern of the vehicle) and on the vehicle itself. The photo on the left shows the IST-ID team deploying the yellow Medusa with the recording SR-1 hydrophone (Marsensing) attached on top (white cylinder).

H2020 announcement: EU has announced WiMUST as one of the funded projects under call LEIT ICT 23 Call 1 - see here.


Kick-off meeting: took place at the project Coordinator premises, Universitá di Salento, Lecce (Italy), on February 26-27, 2015.
