Polyamp has designed a series of sensors and platforms for measuring underwater signatures. The UMISS© is a family of Multi Influence Sensors Systems designed to measure Underwater Signatures. 
The UMISS© MkII Sea Module is in its standard configuration equipped with 3-axis magnetic, 3-axis ELFE electric and a pressure sensor. The use of acoustic sensor as well as a seismograph sensor are optional. 
The signals measured by the Sea Module sensors are digitized using high precision 24 bit ADCs, then merged to a data stream with ETH UDP serial data and transmitted through a cable to the receiving module up to 100 m distance. 
The UMISS platform is designed to be used as a single measuring unit or in combination with several platforms. 3 to +10 UMISS platforms can be combined as a moveable or fixed signature measurement range. 
In such case a UWJB underwater Junction Box is used to merge the platforms data and tranfer via WLAN from a surface buoy or via TCP/IP cable or optical communication (combined with power) is also available. 
No measured data is stored within the platform.
