Attention:
The need of the system has to be announced in cruise planning document "Einsatzplanung" prior to the cruise.
The mounting of USBL antenna is executed by ships crew, the operation of the system must be executed by experienced scientific staff.
GAPS underwater communication is conducted by using various frequencies, interferences with simultaneously operating Echo Sounders are possible.
Attention: Submarine cable must be connected and device must be submerged in water before activating GAPS.
Summary
The Global Acoustic Positioning System (GAPS) combines an ultra-short baseline (USBL) acoustic positioning system and an inertial navigation system (INS) in the same housing to provide accurate position of any subsea object supplied with a transponder. Operating range is up to 4000m water depth with accuracy 0.2 percent of the distance to the object. The registration angle of 200 degree also enables position registration in shallow water.
